12V Heated Jacket Battery Li-Polymer Replacement 12V Heated Vest Batteries Pack Fit for Milwaukee PROSmart Dewalt Craftsman Revean M12 Heating Jackets (5000mAh)

I purchased this because I wanted something much smaller than the m12 battery and the power source bouncing around in my jacket pocket. This battery lasts in between 10-11 hours on medium. It’s very compact and weighs a fraction of the weight. Only complaint is that it seems to take a few hours to recharge. Doesn’t bother me too much. You won’t regret the purchase.

Needed to have a flat battery for my M2 jacket and I went with this one. Works great, last long on high setting and has been charged now 10 times. Charging does take up to 7 hours but it does hold the charge for extended use of the jacket. I recommend if this will work for your needs and price point.

Nice little pack that lays flat and comfortably in the pocket. I run my vest/coat/hoodie, all M12, with this guy on medium while working outside doing construction in the winter and it lasts all day. Excellent replacement for the bulky battery packs that are stock.

Battery life was good for the jacket I have.

It works perfection my m12 heated jacket. It is much more comfortable than the m12 battery and adapter.

I've had this batter for a couple winters now. And yesterday I wanted to really see how it'd do while hunting. Using in a m12 vest. I turned vest on low when I left house. 7am. Throughout the 20 degree day I'd bump it up to medium or high when needed. Got home about 7pm and it was still on. I'm not sure how long it'll last but 12 hrs plus is plenty for me. Came back to buy one for my hoodie so I don't have to swap it around.

Was looking for a replacement battery for an older Ravean coat my wife wears, and gave this one a try even though it is rated at less maH than the one that came with the coat. Much to my surprise, the battery greatly outperformed the OEM battery. On the jacket's highest setting (red), the battery lasts just over 5 hours compared to roughly two hours for the original. The battery also is of slightly smaller size and weight. The only downside is that it takes longer to charge, but that's a minor inconvenience compared to the extra hours gained.

Works amazing, last all day in a m12 hoodie.
