21700 Rechargeable Battery Case Set, 2pack 5000mah Large Capacity 3.6Volt 21700 Tip Battery for flashlights ect,

I have four of these EcoSolutions 5000 mAh 21700 batteries for use with my Fenix CL26R Pro Camping Lanterns and Fenix PD36R flashlights. In my experience they are every bit as reliable as the 5000 mAh Fenix ARB-L21-5000U Rechargeable Battery. They hold a charge well and provide full functionality to Fenix devices - which not all replacement batteries will do. While they aren't quite fully 5000 mAh, they're close... but at 50-55% less expensive than OEM originals, they're a great value while providing a reliable power source.

Perfect fit for my Fenix HM71R Head Lamp. I needed extended battery life for my head lamp and a weekend worth of use without charging. Just pop these in when running low and your good to go! Great quality!

Bought these as first 21700 batteries for a new flashlight. Work great and still kicking after a month. Not sure they hold full rated amps but easy to charge. Would buy again for normal, not high amp use. Arrived quickly so very happy overall.

They are shorter then my Fenix and imalent 21700.Bought them for my xtar pb2sl power bank. They barely fit. Some mods might be needed.I will run tests on to see true capacity, I can almost promise you the are not a true 5 ah battery.I would say just buy the tenerg, LG, Panasonic, batteries and know you’re buying quality.Too early for me to really tell. I probably wouldn’t buy again.After testing they are only 4 ah these are false advertising shame on this sellerBuy real cells, Panasonic, tenergy, lg

Don’t like getting stuck with a dead battery. Always good to have spares on hand.

These barriers are very nice last awhile also! They fit my orca torches no problem I’m a scuba diver and when I use these they work very nice no issues!Down fall is when I want to charge them I have to stick them in my battery charging block and my other 21700s had a usb-c port to charge them and that’s so convenient but I still love these batteries thank you so much guys!

Used in two underwater flashlights. Each Utilized two 21700 batteries 5000 mAh withflashlight on high power (6000 lumens) lasted over hour and a half. Recharged daily for 4 consecutive days. Consistently staying on high beam for hour and 40 minutes.Photo shows testing prior to using.Charging is slow even with USB -C.Performed well. Good price. Recommend I’d buy them again.

These do NOT fit the Geekvape L200 Classic Vape mode. You need to get the flat top batteries. The button top style won't allow the battery lid on the bottom to close.I managed to make them work by squishing down the button face against a table so they would fit.
