JESSPOW18500 Battery, IMR 18500 Rechargeable Li-ion Battery 1600mAh 3.7V for Flashlight, Solar Garden Light and More, 18500 Rechargeable Solar Batteries with Button Top (8 Pack)

Batteries are reasonably priced and so far are working as expected.

Last a long time and charges quickly enough since I now have so many spares now.lol

I have not yet used this product. I liked that it looked just like the picture. I am sure it will work great, but I have not had time to actually use it yet.

great batteries for your solar lights …….

I tried another brand but they were flat topped and wouldn't charge..Ordered these and they worked like a charm.

I have a bunch of old garden lights that used early release 18500 batteries (much lower mAh capacity) they had been performing worse and worse as of late, and it was time to finally swap the battereis out and give the lights new life. They never stayed on this long or bright as they do with these.

Bought to replace the batteries in our garden solar lighting after the original batteries began to weaken after 3 years. The new batteries never held a charge for greater than 3 hours.We reside In Florida thereforeadequate sun to charge them is NOT the issue.Regret this purchase.Addendum:Avoid this company at all costs. They saw my review and offered a full refund. We accepted their offer.Several days after the refund was posted to our account they offered me an additional $20 if I would delete this bad review.Shameful.

I bought eight of these 18500 cells because they were advertised as having a capacity of 1600mAh. When I put these into my tested and calibrated Megacell Charger and ran them from 4.2V down to discharged at 100mA, they only showed a 1300mAh capacity.I ran the test on all 8 cells, and the capacity was 1424 ( best, just one cell ) and 1287 worst... nowhere close to the advertised capacity. They also have very high internal resistance, which is indicative of a low quality cell that may not be able to cycle very many times before they are dead.
