EEMB Lithium Polymer Battery 3.7V 480mAh 303454 Lipo Rechargeable Battery Pack with Wire JST Connector for Speaker and Wireless Device- Confirm Device & Connector Polarity Before Purchase

The voltage is within specification, the battery holds a charge that meets specification, the battery discharges and recharges properly. The product is absolutely, perfectly satisfactory. I doubt that I will ever come close to discharging and recharging anywhere close to the number of specified cycles.

This battery is an exact replacement for the PS4 Hori Mini Wireless Controller (PS4-133, PS4-133A, PS4-134, and PS4-134A models). My controller suddenly died on me only giving me a brief white flash when plugging it in but being completely non-repsonsive afterwards. If this is the situation you're in, this battery can bring that controller back to full functionality.A triwing screwdriver is needed to open the controller by unscrewing the screws on the back, but once that is done, you will see that the battery is taped to the back cover of the controller with a wire plugged into the other side where the circuit boards are. Carefully remove the plug from the old battery and replace it with this new one ensuring that the red cable is aligned with the "+" terminal printed on the controller's circuit board.After that, swap out the adhesive and electrical tape from the old battery onto the new one and insert/stick the new battery in the corner where the old battery was tucked away.

This was close to the same as the original battery in an old bluetooth keyboard, but a bit larger. I had to carve some cardboard out of the way to make it fit, but it works great and has longer battery life than the old one. The connector didn't work and the solder on the old battery ripped off so I just had to cut off the connector plug and solder the new battery's wires to the board, anyway. No problem worked great.

I have a DSO Nano osciliscope with a well aged battery (2013) and needed a replacement. I couldn't find a direct replacement, but came across this battery that was similar. I did some measurements and figured it would be a tight fit (thickness). Received the battery today and installed. Ah yes, a tight fit, but it worked. Cheers!

Battery didn’t work in my unit

Worked perfectly in my application fast shipping would buy again

I ordered this battery for my son's science fair project. It didn't come charged and there was no way to charge it, we could not get his project to work due to this battery. Very disappointing especially to my boy.
