2 Pack 3.7v 2200mAh ICR18650 Rechargeable Lithium Ion Battery with SM 2P Plug

I only needed one and it's a perfect fit/voltage for a Katadyn UV purifier. Replacing the original battery was not possible through the original mfgr, so I had to improvise. I had to replace the connectors and made them all fit, so now I can keep the extra battery for double the use and no need to recharge while on the trail.

I purchased these to replace defunct lithium ion batteries in a couple of rechargeable flashlights that had been in storage for a while. The originals had leads soldered to the positive and negative terminals, so I removed the connectors on the ones I purchased and soldered those wires to the ones that used to run to the battery. The flashlights work like new now.

Work 💪 great

My wife's water pik stopped working a year purchase. She really liked it but it stopped charging. Found these reasonable priced rechargeable batteries for a very fair price,and fit perfectly.

Both didn't charge or work in unit

We bought these batteries for a solar flag light. They work as advertised and expected.

I don't know if it's what I ordered or what they sentThe leads were were wired backwards of what I needed cut and spliced they work great.

I ordered these batteries to replace the batteries and some solar lights they fit they plugged in, but didn’t light up the light so I’m not sure if it was a light was broken or the batteries were the problem. I returned them.
