EEMB Lithium Polymer Battery 3.7V 1100mAh 603449 Lipo Rechargeable Battery with Wire JST 2.0mm Connector for Speaker and Wireless Device- Confirm Device & Connector Polarity Before Purchase

Just what I needed for my component tester. Better than original battery.

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

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!

It does what it should

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.

I have no complaints. Everything was delivered undamaged and in a timely manner. Thank you. Used for electronic design and engineering projects.

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.

These are exactly what you expect and the price is right.
