12v 5Ah Li-polymer Battery Fit for Metabo/Milwaukee/Dewalt/Craftsman Heated Jacket with 12.6v 1A Charger

My husband has to work outdoors at times, and this battery stayed going for 10 hours. He kept it on after he got home to actually see how long to would last. He’s very happy with it.Update- it’s cold again and he went to use it- won’t hold a charge at all. The price has gone up $15 as well so all around, it’s only good for a year?

It's hard to figure out if it's charging. Kinda have to force the charge port around for the light to change color

I bought this battery to replace the battery that came with my Milwaukee heated vest. The battery that comes with the vest is round and it sits on your lower back in a pocket. It is so uncomfortable that I found my self not even using the battery. I was bugged that I bought a heated vest and hardly used it. I found this replacement battery and give it a shot. WOW, let me tell you it is night and day. Not only does sit comfortably in the pocket it actually last longer than the other battery. I dont even notice it in there even when driving. Its so nice to be able to ware the vest and have it heating.
