Hi all,
I just bought a 3400 mAh extended battery on ebay . Is there a way to measure the battery capacity ? I used tbattery, but it seems not work correcly .
I like the battery very much, the battery cover fits 100% . But I still not get the battery to work, the power is still the same as the original battery. Do i need to install new roms or radio ?
Thx for reading !
Yes.
The pay electrical engineer would do it is:
- Have a multi-meter with ampmeter feature.
- Apply an electrical load (small light bulb or resistor) with ampmeter in series across the battery.
- With circuit closed, not ampmeter reading.
- Use stop watch and count how many minutes or hours the light stays running until the voltage drops a significant amount.
- The product of amps and hours is your wattage.
The Right Question is, How your device measures it?
Have you tried to remove and put back the battery again after your device says that the battery is over?
Yeahh, I just bought a new one 2300 mah by Leicke for only 20 euro. Used tbattery and it shows 2300 mah, the cover fit, kickstand is metal. Very happy now, thx all .

I recently bought a BA battery advertised as 2400 mAh for around $20 US.
However, it only charges up to 58%. I've tried charging it for 8 hours or more, discharging it a little bit, and recharging it, but the indicator never goes above 58%. I am charging it from inside the BA, with USB power.
The battery says:
Replacement for XDA III/MDAIII
Model: PH26B
Rating: 3.7 VDC == 2400 mAh
Rechargeable Li-ion Polymer Battery
...
Made in China
Researching some more, I notice that the "PH26B" part number is used on both 1500 mAh batteries and 2400 mAh batteries, by different sellers. It can't be both, can it?
The sites which list it as 2400 mAh tend to be less reputable sites from places like eBay, with deals which seem too good to be true.
And yet the battery I bought says both PH26B and 2400 mAh on it, so it is not simply the seller misrepresenting the product (i.e. if it's a scam, it extends to the manufacturer).
My questions are:
1. What exactly is the PH26B designation, if it is not a unique part number?
2. Are there any model-specific compatibility problems between certain batteries such as PH26B, and certain models of Blue Angels, or are all BA batteries interchangable between all BA models?
3. Is there a scam going on where BA batteries are being sold as 2400 mAh, even though they are only 1500 mAh? The 2400 mAh battery I have, is not much thicker than most 1500 mAh batteries, which makes me suspicious. (It is only about .5 mm deeper than the BA case where the "Windows Mobile" logo is printed.)
4. Why does my battery indicator stop at 58% with the 2400 mAh PH26B? (I've tried it in both my SX66 and PPC6601, with the same results.) 58% is approximately 1400 mAh / 2400 mAh, so if the charge indicator is a measure of the true charge as compared to the claimed capacity, then 58% would be what you'd expect from a battery which is only 1500 mAh but claims to be 2400 mAh.
5. I've often heard that you must be careful when first charging BA batteries, or else permanent damage could result. I did everything "by the book" -- backed up my data, changed the battery in my BA to the new one, and left it charging in the BA for hours -- but it still only goes up to 58%.
6. Do I need to do a more severe hard reset, such as leaving the battery out for 30 minutes, and/or completely draining the battery before recharging it, in order to get the charge cycle fixed?
I know I can trust Lion Battery (whose 2400 mAh Mugen batteries cost around $72 US instead of $20 US). I've already done business with them before. I am not in any immediate need for a BA battery. I just recently bought a spare one as a "deal" which was apparently too good to be true, and I'm trying to figure out the origins of it, since it's apparently very widespread -- simply search Google or eBay for 2400 xda, and you'll see hundreds of deals for these 2400 mAh BA batteries for under $20 US. It's so widespread that I don't think it's bad resellers trying to rip people off, but a bad manufacturer misrepresenting their batteries (and spoiling the good ones), or some kind of mass confusion about BA battery types and their true capacities.
Or maybe I'm too cynical, and I simply got one defective battery out of a normally good lot.

Already read that. No help there.
There are 2400 mA batteries out there that do NOT work correctly. We worked with our mfg for 3 mos and six different revisions before we could get a working battery.
Chances are the $20 battery is some of the early batteries that did not have the microcontroller on the battery programmed correctly.
16 hours after charging with an AC-adapter-powered cradle, the battery has gone down from 58% charged to 9% charged. The backup battery is down to 75% charge.
The cradle is being supplied 5 VDC at 2A (USB current is not usually enough to charge batteries -- only to sustain their charge).
The battery is not being charged in the auxiliary slot, but is inside the PDA, which is docked in the cradle.
I have removed the battery for 1 minute, then reinstalled it. The main battery indicator still says 9%. The backup battery has gone up to 100% in less than 5 minutes. I may need to remove the battery for longer than 1 minute to force a hard reset.
The indicator LED is blinking red-orange every three seconds.
I will leave it to charge some more, but I expect it's a DOA battery that should be returned or trashed.
Is it the capacity they write it ??
I think they can also said the battery with 8000mAh... it's very simple
reprit the label and mark it as 8000mAh with the same battery..... 8)

They say 2400 mAh. There does not appear to be any evidence of tampering with the label, which means it's not some amateur glueing or writing "2400 mAh" on top of a 1500 mAh battery, but something more sinister.
Without being sarcastic, could you please tell me whether there really is such a "reprinting" scam going on, and what the true capacity/designation of a PH26B is? What other signs to look for, and how to determine the true capacity (by special charging methods, by physical examination of the battery, etc.)?
I'm guessing it's some Asian scam, where some manufacturer is printing look-alike labels, and overstating the capacity of the batteries, and selling them at a very cheap price to resellers, who then go online and sell it for 50-100% profit, while still looking like a "bargain" to the real 2400 mAh batteries, such as Mugen's. (BTW, do you really work for Mugen?)
How can we tell the fake 2400 mAh's from the real ones?

I know about Mugen batteries and their reliability. I have some. I'm talking about cheap knockoffs which claim to have 2400 mAh capacity but which don't. It's a widespread scam going on right now.
It may not necessarily be a scam, just very, *very* shoddy goods. As you said probably asian and very cheaply made. I suppose you get what you pay for...
Here's a pic of the bad 2400 mAh battery. It uses the same part number which I've seen on many 1500 mAh batteries.
PH26B is likely just to be the shape and connections... so you know any PH26B will fit a BA (or any other device which might take a PH26B)

leek,
yes..I am from Mugen Power. You can check it out from my post.
Actually....smart guy should know that.....how can they make profits if they use good quality of material to make the battery pack and sell it at this kind of cheap price....
if they write the capacity is less than 2400mAh, do u think u will buy their battery .... I don't think u will spend money on a battery with capacity lee than the original..

Hi, I have it now for 6 month now and its workingOK for me.

I am using Hastarins 7.6 kernel with ext batt support and Froyostones 3.2 build (Most recent as of Oct 23)
I have done some extensive research, although, i have not yet figured out a way to get an accurate reading, in android, of my extended battery (life percentage)
I have calibrated my battery (charged to 100% w/ phone on, shut off phone and charged until green light, then booted android, then turned off and charged again until green, then turned on and booted android) only to find out that the battery discharges at the same rate as with the original battery all the way down to 0%.... but does not recognize that the battery holds twice as much power. so really, the 100% battery drains to 0% on extended battery but does not recognize that the battery still holds 50% of its power left
i have never deleted my "batterystats.bin" Because i can't find the file anywhere using a root explorer and even recovery, although, i was told that this step is not necessary in calibration.
I have current widget and my draw is around 60mA on standby with BOTH original and extended batteries but It seems the android OS cannot get accurate readings on the extended battery? It cannot multiply the battery meter by 2 so that the drainage is reciprocal to the larger battery, thus resulting in a slower drain (like 10%/hour drain with original battery would equal 5%/hour drain on extended) ?
correct me if i'm wrong somebody please, or am i missing a step (besides deleting the batterstats.bin which i cannot find out how to do even after downloading recovery)
anyone have any information on this ratio?? battery percentage reading and the extended battery? will they ever be compatible for correct readings??
i've got the same problem with a cameron sino 2400 mah battery, but not only on android! i also got the problem on windows mobile (on every radio and rom version).
after removing the battery out of the device, it will show the right percentage of the remaining batterypower, but the batteryindicator is still falling in the speed of the normal battery.
i couldn't find any solution yet, but maybe it's a battery internal problem of the chip inside the battery.
it looks like the device is reloading the battery-chip-data only when plugging in the battery.
can you tell me, if your battery also is a cameron sino battery? or is it an original?
have you recallibrate your battery? Let it drain till 0%, and keep try to turn device on until totally no vibrate, then charge to 100% after 100% turn phone off and charge till green light, unplug and charge with phone off for a few times.
i already calibrated mine many times, but no change in the result.
i have read from anywhere else in the internet, that most people got that problem with chinese extended batterys.
one of that guys ordered a 2300mah extended battery from the manufacturer leicke - looks like it is maybe the same as the original one and he said, the new battery dont have the problem anymore and is working correct.
i ordered the same battery yesterday (for 21,- euro) and i will test it myself. i think the problem is the chip inside the chinese batterys, that will tell the device its a small one.
by the way, my cameron sino 2400mah battery is made of two small batterys that are linked.
i disassembled it!
Thats guy is me ^^ . But I i really dont see the big different between extended and the original . Must i really do the "recalibrate thing " ?

update: now i've got the leicke 2300mah battery with backcover and metal kickstand.
cover is fitting 100% and all looks and feels like its made of high quality.
the batterydraining ist detected correct and i dont have to remove the battery to see the current chargelevel.
the problem was that chinese crappy battery!
only one thing for androidusers: because of the most kernels don't support the extended batterys (temperature is reportet wrong and android is shutting down after booting), you need to change to a kernel like hastarin 7.7 or 7.8 that is supporting the extended batterys.
overclocking of the hastarin linux kernel work with overclock-apps, so there is no need for an overclocked kernel.
i'm very happy with that battery and it cost only 21 euro over amazon in germany.
i will never get a cheap chinese battery again
So, is it correct that batteries have some kind of chip in them?
yes, they do contain microcontroller
cheap chinese ripoffs often are just badly designed, made from low-cost cells and are very dangerous to use
So don't be surprised if your 'OEM' seico, chinapower, mugen, or whatever name doesn't hold promised charge or even work as original battery
I have replaced original BA battery with 5 lithium batteries (3.7V 2400mAh each) according to this thread http://forum.xda-developers.com/showthread.php?t=556448.
I have connected them in parallel and joined with corresponding wires in battery cover. When I charge them with original BA charger they get to almost 4.2 volts. When BA turns off because of low battery they have 4.1 volts. So they last for 2-4 days of common use. But people in the thread are talking about two weeks or more.
I don't understand why BA uses only 0.1V if it has another 0.4V available to completely discharge battery.
What can be wrong? Where is the difference between mine batteries and theirs?
How long does the charge last with original battery?
volts don't get used up like a tank of gas . . .
you need enough to run it
and your volt meter may be inaccurate but you comparing the result with past performance would be most relevant.
hi just have a question, howcome my newly bought xp 2000 energizer could not fully charge my sgs2? seems that it can only charge my phone 80%.
These were the following conditions when I used XP 2000:
1. xp 2000 was at full charge
2. my phone was turned off
3. my phone was not drained, still had around 10% charge.
I noticed like around 80% of charging, a temperature icon showed blinking as if the battery was heating up(sorry i don't have a screenshot).When I tried to unplug xp 2000 from the phone, the charger no longer have lights on, as if it got drained w/o fully charging my phone..
This is my 2nd of unit of xp2000. The store where i bought it replaced the first one thinking that it might be defective but same goes for the new one..
the temperature icon I mentioned only shows up whenever I use xp 2000.
Well the Charger can store some amount less than 2000mAh of Energy. The SGS2 battery is rated at 1650mAh. So in theory you have 350mAh of additional power in the pack than you should need however the battery is still draining while it is being charged (the SGS2 can draw up to 1A current according to specs and even in the deep sleep state I wouldn't be surprised if it draws 50-100mA since the hardware doesn't support true power gating. I mention earlier that while the charger is rated at 2000mAh it can probably on store up to 90% of this value aka 1800mA.
In summary:
The capacity of the power pack is closer to 1800mAh that 2000mAh.
The phone draws significant power even in deep sleep.
There is additional power lost by transmission and charger control circuitry in both the power pack and the charge controller in the phone.
There are additional reasons but those are the main ones.
That is why you cannot fully charge it with a power pack.
Please press thanks if you find this information useful.

ok thank you! one rep from energizer had somewhat a similar explanation.Well, I guess I'd have to accept it as is... If only I knew, I could've bought one that has a higher mAh, like xp 4001... so sad.... anyway appreciate it!
On theory, a 2000mAh is capable of charging a 1650mAh battery as long as power is not lost through other means.
Most of these battery packs do not have a Zener Diode, you might want to modify it to add it in. This will allow your 2000mAh pack to charge your 1650mAh battery for 1 time only.

How can I modify it? sorry..
I use an xp2000 with my S2 - but I think of it as a battery extender, rather than as a primary means of recharging it. I use it when I'm working & the battery's getting a little low - it can keep ahead of the phone and gives me another 3-4 hours in total. The great advantage (over a spare battery) is that I don't have to power down, so if I'm downloading, for example, and I don't think the battery will make it to the end of the download, then I just plug in the xp2000 & the problem is solved.
I have lots of different ways of charging - mains & car chargers, USB cables, spare batteries - and find the xp2000 is a useful addition that sometimes saves the day. It's just the right size & weight to be able to carry around without having to think about whether you really need it - so it's always there when you do.
If you're using any state-of-the art smartphone intensively, it helps to have a variety of recharge options, and to take advantage of any opportunities you may have to top up during the day, thus keeping ahead of the phone's discharge curve.
Hi folks ,
My battery seems to being done so can any of you can share your experience with aftermarket batteries or a link for Official OEM battery from LG ?

The battery I got with my phone I suspected was not original. The battery meter would drop several percent shortly after charging the phone. I then read the comments that originals aren't made anymore and shopped around to see whats out there. I know those chinese sellers are lying about battery capacity since they do it for every battery type out there. But I wanted to do a little baseline for my current battery that came with the phone. The cheapest way I saw was to use this USB charge meter that shows voltage, current, power and capacity in mAh. So I discharged the phone down to 2% and then connected it with the fast charger (5v stock charger) and used the meter to measure how many mAh were consumed. The phone was put in Airplane mode and the screen left off. A couple things to note, the phone itself even though in airplane mode and no apps running will in itself consume some power, it will be very little and will be negligible for this test. The meter itself uses power but the mAh counter does not run up with that power being consumed and if it did it would be very little. Lastly even though the phone said there is 2% battery life left that is not true, because it is setup to prevent the user from over discharging the battery because that will destroy the batteries internal structure. So I do not know what the minimum voltage is for the battery when measuring the capacity ( and I really don't care at this point) the reading I get is for what a normal user would get from using their phone till it shut off on them. The value I got was 1960mAh, the battery claims to be 3000mAh. It will be interesting to see your results even those with extended batteries.

I just got a Beltron battery from EBay (user: Beltron) and the battery arrived DOA and would not take a charge. The initial voltage was 3.4V and got it up to 3.7V (dead for a Li batt.)
Battery dated 7/16/15, kinda BS that they wouldn't precharge or test a battery. Unless its a scam in the hopes that the buyer will just throw it in the garbage.

Go for polarcel akku battery it's good one. ...
I got an Anker battery and it is so awesome to finally have a proper battery for my G3. I will test the capacity when I get a chance but I can tell it's as good or better than original.
edit: Tested capacity and it is a little over 3000mAh
I'm thinking about ordering the Anker 3000mAh Li-ion Battery, but I'm also considering getting (preferably) the, Perfine 3000mAh OEM Li-ion Battery, because they both have IC Chips but,
the Perfine has IC Chip states it has all these features; "prevents short circuiting, overcharging, overheating and lengthens battery life"
the Anker IC Chip only states its features; "prevents overcharging & prevent short-circuiting"
BUT in the Perfine info at Amazon it says -Without NFC functionality.
AND I have My LG G3 which has the OEM cover, with GPS/NFC parts embedded into the back.
So my questions are this;
1.)Do all IC Battery Chips have all the same great features, and they just didn't state all the features on their Amazon page? Or Does the Perfine IC Battery Chip really have more IC features?
2.)My LG G3 has the OEM cover,GPS/NFC parts embedded into the back. Do I need a NFC/GPS battery for NFC/GPS to work? Or will my cover be all I need?
3.)If my OEM Cover is all I need will my GPS/NFC take a performance hit?
