Keeppower Protected 18350 Li-ion Rechargeable Battery Button Top 3.7V 1400mAh 5.18Wh for Flashlight (NOT High Drain) (2 Pack)

I want to say thank you Chuck for highlighting this feature.. these fit the Wuben E7 like a custom glove. I was having trouble finding one that wouldn’t turn off when you shook it.Can’t wait to battle test them.

I work in the tactical firearms industry, and lights play a big role. And batteries play just as big role. Low quality batteries can render a top tier platform ineffective. These batteries have always given us great results. Normally it try to buy them in bulk, but in a pinch I get them from Amazon. Can’t go wrong with this brand.

I received these keeppower 18350 1400mAh batteries yesterday and tested them. One was 1530mA and the other was 1380mA well within acceptable range for me. They are protected but still work in my sofirn IF19 & SP40. I tested them with my liitokala lii-m4s battery charger and it has a 5% variance. 18350 with high mAh are getting hard to find and I recommend you get these. 1400mAh batteries.

Keeppower Protected 18350 Li-ion 1400mAh. Given Keepower historical reputation in the Battery world, we bought two April 2024, and used . recharged them just a couple times .5 / .25C on Thrunite and XTAR chargers which still work with other batteries. Both Keepowers will not initiate a charge. Never had problem like this with Eneloop, Eveready, Duracell, Sano, Panasonic, Thrunite, other top mfr. Very disappointed in this Premium priced 18350. Barely 1 year old and with minimal usage, always stored at confirtable room temps. Would not buy again, do not recommend. Sold by UKWELL and Shipped by Amazon.

If you are looking for a button top, 18350, protected cell then this is good one. The only problem is right now a 2-pack of these are selling for $24, which is about twice as much as they should be, and about 1/3 more than full retail. Shop around for better value. Some lights or devices may do better with a lower capacity, higher drain specification if you like blasting high lumens. Good lights now contain protection circuits in their lights, so they are not always needed any longer in the cell.

Purchased these for a Radiomaster Zorro RC aircraft controller, which uses only 18350 batteries in its internal bays, but they are too long to fit between the contacts without breaking something. Not sure how a battery, built to a certain spec. cannot fit into a device built to hold batteries of that same specification. Wasted my money, I guess.

Needed a 18350 button-top, high drain, battery. However, these were too long for the red/NIR torch I have. Refund given so satisfied but still looking for right size battery.

Excellent dimensions for a Wuben E7 rechargeable battery. Hard to find 18350 battery with the right dimensions. Glad your description was clear enough to state it. Thanks for taking the time.
