I found a bigger battery for Defy MB525 which has(theoretically) capacity rated as 3500mAh(it is much thicker than original battery so there is a possibility it will last longer and that it isn't only a sticker with bigger capacity printed on it). However the problem is I own Defy+ MB526 which battery is 3.8V and the bigger battery voltage is only 3.7V. Is there a way to change Defy+ kernel to Defy so the battery will work properly or should I put it in without any changes and it will work fine as well.

My Defy+ battery isn't charging anymore, even in other Defy, it only charges with an external wall charger, so I'm gonna buy another one.
In my country, the Defy (MB525) BF5X battery is a lot cheaper (less than the half price) than the Defy+ (MB526) HF5X battery.
The question is: The Defy (MB525) BF5X battery is fully compatible with Defy+? I can use it without any problems?
Note: I'm using the WIUI GB v2.9.27 (GB Kernel).
Thanks!
battery fix available here:

note: bf5x and hf5x differs in battery chemistry and the top charge voltage slightly different (hf5x higher), so if you use hf5x on mb525 rom the battery won't full charge, but if reverse, theoretically can be dangerous(???), not 100% sure but overcharging lithium rechargeables is dangerous, tight voltage limit...

Hi there.
I hope is not too late - last post was in November.
I've tried a new BF5X battery with my DEFY+ (MB526) but it causes bootloops or shudden shutdown when it asks to enter the sim pin.
I've also tried with and old one from a used MB525 and it worked without any problem... What can I say...
I should advice you to buy the HF5X, even if it's more expensive, for sure compatibility.
I bought a replacement battery for my defy because the stock battery has bulged and now quickly loses its charge. I got the new one from eBay and it has, 3500 mah. I'm currently using Mokee OS for my defy but the battery percentage that it is showing doesn't seem to be accurate because it has been at 1% for more than 12hrs now, no kidding. I have wiped the battery stats for this after the first full charge and I also used battery calibration. Has anybody experienced this when they replaced the battery?

You should flash your Phone with battery fix appropate to New one. try that one for defy+
That's what you'd get when using different capacity from stock ones.
Defy/Defy+ would recognize only 1500/1700 mAh batterys, it's fixed in the rom.
There's no fix for Hi-capa battery, you may just live with it, or try Momax 1500mAh if you like.
Try it with different battd binary files. According to this video it can work correctly.
Hey all,
I'm having a defy red Lens running cm 7.2 official. My battery's capacity has reduced a lot and I'm forced to take my charger to college as the battery would have only <10% left by the end of the day.
I'm planning to buy a hf5x battery , but i came to know that hf5x can be charged to a Max of 80% only without the defy+ battd. I have two questions
1: Can i use hf5x and bf5x simultaneously if i replace the battd & lib files to suit hf5x to charge full??
2: Should i buy a wall charger to use both batteries simultaneously??
Thanx

I have seen batteries for the Defy that are the same physical size as the standard battery, but have a capacity of 2500 mAh. Are these batteries as good as they look and will the battery monitor in the Defy work properly with them?
Thank you

I got such a battery and it is CRAP.
Bought it with the same thinking but after that I went and bought Original Moto Battery for my old Defy Green and it holds longer and no need of extra hassle to flash battery fixes.
Buy Genuine Motorola Battery for your device and will be times better.

Does using a Defy Plus battery in a Defy make much difference to the battery life?

Not really, probably just a tiny bit more. The MB525 battery starts to fade after 2.5 years, it's clearly evident in the case of mine.
I believe walter has a fix in the form of a zip that you have to flash if you decide to put a Defy+ battery in a Defy. Im not quite sure though, I haven't visited his google drive in quite a few months.
i implimented a 4000mah battery into Yureka plus with keeping old battery's board fitted in new 4000mah battery , but backup is same as 2500mah !!
i even compiled a kernel based on AR_beast R9 with the changes in souce files responsiable for mah of battery and charge (just searched in git hub with term "2500") and changed them with 4000) and also changed framework/res/xml/power_profile with battery_capacity = 4000mah
where i am wrong ?
is there any special file which is responsiable for charge to give battery it's peek mah threshold limit ?
and also explain how to calibrate battery with the changes.

sorry for my bad english
Are you able to use this battery?
You should not use protection board from old yureka battery over new lipo pack. Which phones 4000mah batt are you using? Most lithium batteries(70-90%) sold in india are fake and hold half of the stated capacity.
The 2500 thing is just a label. The charging ic doesn't care what the label says. It simply continues to put charge current until voltage reaches 4.2v(for li-ion). The yureka charge IC maybe be charging till 4.35v because bundled battery is lipo.
Drain till 0% and charge back non stop. It should charge it full 4000mah
else
Use a knife and scrape off all traces leading to the main terminal pads on the yureka battery PCB. Then solder enamel copper wires from old PCB to new PCB. You'll have to place old protection board on existing board.
you are scamed

hello, i have also using 4k battery (bm47) on yureka, i modified the kernel to adjust the charging voltage and battery capacity according to bm47 battery. join this telegram group , i am available there, https://t.me/yureka
