3.7v Lithium ion Battery 18650 Rechargeable Flashlight Battery Real Capacity 1800mAh 2Pack for Headlamp, Solar Lights, Remote Controls, Mini Fans Button Top (Blue)

These are just what I needed for my outdoor sensor light. Works great now!

Fits and works perfect for my Costco motion sensor solar lights.

Seem to work pretty well. Haven’t used them too long yet. Need some sunny days.

As soon as I put this battery in the flashlight it began smoking! I quickly ran outside with it and took the flashlight apart! The battery was smoking inside the flashlight! Buyer beware!

Works great

These rechargeable batteries work great in my solar lights. I was unable to find these batteries in any store, so I had to order online, and they are just right.

Great just what we needed

The sets of QOJH batteries I tested here surprisingly did quite well. The tested capacities actually matched the advertised capacity for once. This is very uncommon for an off-brand 18650. Usually they fall in the 50 to 66% range of the rated capacity. However, these were an exception.I also tested a 3000 mAh version of these batteries sold by QOJH and they tested out to only 1947 mAh (65%). Given the inconsistency, it is difficult to say if the next batch on 1800 mAh batteries from this supplier will test this well.Whatever you end up buying, try to stick to the reputable brands. Stay away from the off-brands if possible, especially the ones with high capacity claims. You've most likely seen 9900 mAh batteries advertised...the capacity of major reputable brands top out at 3500 - 3700 mAh. This should tell you something.
