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.

Hey guys,can anyone help me with the atom battery? right now i am using XP-02 1530mah and its backup is very short...so is there any solution for this?
Buy a new battery or get a higher MAH battery and of course you have to bear with the thickness of the battery
i just bought a 2400mAh battery from www.worcell.com the battery stands for 3and half days using the WM6.5 by khoa ha that really consume battery life. i'd rather the performance than the thickness
how much it will cost for in rupees for 2400mah battery..?
Considering the fact that my x10 now completely redeemed itself.
I figured getting a nice fat battery would just completely make my day.
Are there any?
Stock battery is 1500mAH so:
1800mAH battery,
LINK
or 3600mAH battery (Makes your phone fatter)
LINK
so is this worth it? does this make the phone fatter? (i dun mind bout the weight)
1800mAH battery
Hello guys
Do you know what is the máximum charge for the bh6x and the bh5x
I wonder if for the bh6x is 4200mV, i'm having a several battery drain and i want to make sure that the battery is in good shape
bh5x is the one that came with my phone and i'm not sure of it's maximum capacity too.
I recently replaced my battery with the same one that came with the phone. Found a relatively cheap OEM on eBay, and I charge it every day (sometimes twice on days with really heavy usage).
IDK the maximum charges, but you can kinda tell when a battery isn't as strong as it once was when it came with the phone.
Then again this is EXACTLY why I want removable batteries on my cell phones and absolutely HATE integrated battery cell phones... (IDC how "cool" the phone looks)
Sent from my GT-I9100 using xda premium
I have both of those and the maximum charge i get on the bh6x is 4200 and the bh5x is 4174
Hope that helps

Thanks. i found out that both charges uo to 4200 but everything depends on the power per hour they can deliver
Thankyou
Hi, I began using a 5000 mah battery for Xperia UL from mpj, and I installed battery monitor to see battery life. The phone is saying charge your phone at 14% while battery monitor is at 55%.Will it keep going when the it hits 0%? How condition to 5000 mah? Thanks
