Review: Last twice as long as original battery. - I swapped this battery in place of the OEM unit and I’m genuinely impressed — it works well, and it stays charged significantly longer than what I had before. The build feels solid, the voltage holds steady, and it gives me peace of mind that I won’t be scrambling for a recharge mid-use. If you’re looking for a dependable replacement that punches above its pricing tier, this one’s a great pick.
Review: good replacement battery. - I used this in a ultra-light flashlight I designed for my drone. I picked up some tiny single cell charger boards with built in low voltage cut-off to make a tiny battery pack. Worked like a champ!

### ⭐⭐⭐⭐⭐ good replacement battery.

### ⭐⭐⭐⭐⭐ Actually 1100mAh as it is rated!
*by P***Y on May 2, 2023*

I used this to replace a battery in my Sony Dualshock 3 controller for my PS3. I needed a battery and didnt want the standard size official Sony battery as theyre very small, in the order of 500 mAh or so. I installed this and it fired right up even without charging it which is a good sign. It takes twice as long to charge the controller now, but it lasts seemingly forever now. ive used it daily for almost 2 weeks now and it still says I have 2/3 charge. I would highly recommend this battery to anyone looking to do the same mod. It fit in the old battery spot perfectly fine, but I did place a bit of foam between the motherboard and battery to keep the solder points from poking the battery body.
