Mobile Warming 7.4V 2.2Ah Lithium-Ion Battery

Nothing I disliked. It was exactly what I thought it was for its size and shape

I ordered the new battery to replace the one for my vest that died the end of the ski season last year. I took it out of the box and charged it and it is not working. When I plug it into my vest, it just says it is charging and won't heat. I haved tried everything, and at this point it is locked on with lights at 100% and I cannot get it to shut off or do anything.

This is a factory replacement battery for Mobile Warming clothing.

Good product but confusing applications, so if you can, do your homework. There is no compatibility chart available anywhere for Mobile Warming batteries and even though the batteries look the same and have essentially the same output characteristics, they may not work in your Mobile Warming item. Adding to the lack of clarity is that none of the product descriptions, here or anywhere else, list the actually part number on the battery (ASA-----) so it's impossible to determine if your buying the right thing. This item, the grey battery in the photo, did NOT work in my older Mobile Warming Ansai jacket so it was a waste of money.

As numerous others have experienced, the battery matches the specs of the original battery that came with my vest not NOT work with my +Venture vest. Waste of money

Perfect replacement
