3.7 Volt Rechargeable Battery 3500mAh NiMH Battery 2Pack Large Capacity Batteries for Headlamp, LED Flashlight, etc ZH

Seems good and holding charge well. Used in a battery carpet sweeper.

So I got these rechargeable batteries for my vape (voopoo drag x) because as you know after some time if batteries are recharged every other day they become less effective.With that in mind I wanted something less expensive but does the job without any safety issues (it's a big concern of mine no one wants anything catching fire or explosions)I did my research and stumbled upon these.I like that you get two so you never have to worry about not having a fully charged battery because there's always a spare.They quality is great it charges well and quicker than some others I've had and the length of charge I get from each is longer than others too making it well worth purchasing!! As I use the batterys for baling I can't comment on their uses for other items such as lighting etc so brightness I don't know but considering they hold charge for a long time on a high powered vape I would imagine these would be extremely useful if you wanted to use them in a light.

Right batteries for my sub ohm vape, easy to select the right ones on amazon, needed the flat end type, glad I didn't order the button end ones! Seem to be working fine.

Bought 4 of these batteries as replacement for existing 4 Efest 3500mAh batteries. Exceeded all expectations by far compared to the much expensive brands. Vaping for 2 full days with my Geekvape Legend 3 without needing to recharge. 100% charge held over 3 days so far. All four batteries performing great, happy days.

Good batteries well packed

needed 2 new batteries for torch/flashlight. when inserted end-to-end in the torch the battery terminals cannot touch each other because the +ve terminal is too far recessed and the outer plastic wrapping prevents it from touching the -ve terminal of the other battery. they will probably work on their own but that is not what i needed and not what you would expect from any battery; they should be able to be connected together. I decided not to go ahead with a return as it wasn’t direct to Amazon and I’d have to pay. Without asking the seller contacted and issued a refund so I can’t fault their customer service. Thank you

Great seller!fast deliveryRecommended

Pure and utter crap, one never worked the other didn't charge
