JESSPOW 18500 Rechargeable Batteries, IMR 18500 Rechargeable Li-ion Battery 1600mAh 3.7V [ for Flashlight, Solar Garden Light ] with Button Top (4Pack)

Worked instantly!

These batteries store more energy than the (equivalent) ones I replaced in my lights and work very well.

An excellent value: these Li-ion cells ("batteries") test at over 1550mAh each in a BT-C3400 tester, which I consider fully compliant with their specification.Just one thing: Make sure you are ordering the correct cell. These are 18500 cells. The most common cylindrical Li-ion cell is the 18650. If you are looking for a Li-ion cell that is exactly the same size (but NOT the same voltage — careful!) as an AA battery, it is the 14500 cell.

Kind of mixed Right size Som seem to hold a charge better than others. I tried to solder these together. The + side would not hold solder. This could be the reason some don't seem to hold a charge as well.

Awesome

As expected. Replaced the dead battery and saved a $60 set of solar light fixtures.

I bought these seeing they were cheap rechargable batteries for some of my solar lights. boy did i miss theboat on these first off, i ahd to wait 3 days before these were charged enough to last more than two hours powering 3 150 lumen solar lights. two the batteries only ever lasted 3 to 4 hours on a full charge, i had pulled them out and checked them 2 of three times during the summer to verify the charge they were holding, but the longevity is severely lacking. last year the energizers i had had in the fixture for the three previous years would last until iwoke up at 5 am. but not these. save yourself the money and pay a little extra.

Fast delivery.
