YTKavq 18650 Battery, 3.7V 2600mAh Rechargeable Li-ion with XH2.54/2P Connector for Flashlights, Drones, RC Toys, Electronics，Please Check Connector Polarity Before Purchase

I bought this to replace a failing outdoor speaker power source. The battery had the same plug installed as my outdoor speaker and it had a larger capacity as well. Worked great.

These were the perfect replacement and have lasted longer than the original batteries. Would recommend for replacement of any outdoor lights.

It wasn't fully charged when I received it and it initially wouldn't take a charge. I let it run down to fully discharged, then it finally charged up, but didn't hold the charge. I charged it again and now it seems to be working okay. Time will tell.

If you have a snap on flip up light this is the battery for it. My dealer told me the light isn’t under warranty and to get it replaced would be 90 dollars. He wrote the part number down so he wouldn’t forget to call on it again. I googled the part number found this and it works great. Exact size and plug.

Battery won't hold a charge. Also, the diameter is larger than described which made me have to dremel out some plastic. Returned.

These batteries were purchased to replace the rechargeable batteries in lighting devices.Whilst the connector was not needed, the wires were.The new batteries were perfect replacements for the tired batteries and are working quite well.

The media could not be loaded. Got this as a backup battery for my grandson’s remote control car. It has the same voltage, connector, and shaped the same but it was just a bit too long to fit inside the compartment. Make sure you measure before purchasing just to be safe.

Have used these three times now to replace worn out batteries in equipment I use. Had to splice the correct connectors on, but no big deal. Upgraded the capacity also!
