SAVIOR HEAT7.4V 2200MAH Rechargable Li-ion Batteries, for Heated Gloves Socks Hats Balaclava(Battery only)

One charged a little quickly, when first charged. I was a little worried about that, as I bought one from someone else, and it also ran out quickly.Not the case with this one! They charge well and run well. With two sets, I am good for an entire day of skiing.

Great replacement for my heated gloves

I bought these to use in a heated hat I have. I keep it on high and the batteries do wear down fairly quickly so I like to have one in the hat and another I can swap out with. I wish the battery life was longer and the batteries were smaller since it is on my head but that is a first world problem I would say. These worked good and I had no issues with charging them or using them in my hat.

After two years of use, the original batteries in my savior gloves started fading after just an hour on the highest setting.These replacement batteries are great, they hold a charge longer than the others did when new.Very satisfied.

I almost live in my heated vest on cold outings & when cold indoors. Having an extra set of batteries is important to me because I never want to get stuck in the mountains in cold weather and not have the option to stay as long as I like.Truly satisfied!
