    • 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. ... show more

    • 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!

Is as described. The JST connector is not wired for microcontrollers but RC things so be aware.

    • Actually 1100mAh as it is rated!
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. ... show more

    • better specs than original device
This is the same form factor as several devices I have such as a GPS but it has greater capacity. With the standard tiny plug it will easily just plug in if you manage to take the device apart without damaging it!

Turned out to be a perfect replacement for the dead battery in my aftermarket Wii U game controllers.

    • Battery doesn't hold charge
Used this to install in my Dual GPS sensor,the battery charges fine and works for a few hours , but if it sits for more than a few weeks, the battery doesn't hold the charge. The original battery that came with the unit would hold charge for many months between use.
