Used these in my heated ski gloves. Unfortunately I was only able to use these 2 times within the 30 day return window and one battery is not holding a charge and they can’t be returned. The other battery is only lasting several hours where my other smaller batteries would get 5-6 hours on the same setting. I would not purchase these batteries.

They work well with my heated gloves. They last a lot longer than the batteries that came with my FXR gloves.

I have dedicated special equipment to accurately charge and discharge all kinds of lithium batteries, including these. (single photo of several attached) This is WAY more accurate and repeatable than just testing use time in the gloves.The BEST I could get was 2530mAh @ 0.5A draw. The WORST was 2288mAh @ 2.0A draw (see attached chart). That is within the expectation of use in a heated glove from low>High. This is 64% > 72% of claimed capacity. This is a disappointment. I wrote the seller about this and they apologized and said I could return them for a refund.Unfortunately.....having tested a LOT of after market batteries (cameras, phones, etc) I've found that the claims are inevitably inaccurate and overblown. I can almost guarantee ALL the batteries of this sort, no matter which seller, will not measure up to the claimed capacity.The original 2200mAh were similar, but they did have a season of use before I tested them. I was hoping to improve considerably on their size/duration. These are better, so I will keep them.

Use them two times ran them dead both times fully charge them they're rated at 3500 milliamp hours but my 3000 milliamp hour batteries that came with the gloves last 3 hours on high I get an hour and a half on high out of these so how can they be rated at 3500 when they last half as long as the 3000 mAh

Good replacement batteries for my Snow Deer heated mittens. Went skiing a few days ago. Hands were warm all day. Combination of mostly low heat setting with some higher settings first thing in the morning and after a mid day break in the lodge. Always good to have a spare set of batteries especially on a long cold day. Smaller batteries usually only last 1/2 day once they are a year old or so. This size battery is optimal.
