Question: Does this battery come charged or do i have to wait for the charger to properly charge the battery.  just making sure it's the battery and not my vest
Document: Awesome! Shipped quickly and plugged right into my older charger and vest and still worked! I was worried that the new battery might not work on my vest, but it did! I use this under my motorcycle jacket to stay warm. I just wish I would have bought it sooner.
I purchased these as extra batteries when I ordered gloves for my son. They are the same kind that come with the gloves and are very easy to charge and use. Having the extra batteries makes sure his gloves will always have the power they need to keep his hands from turning white and numb from Reynaud Disease.
I bought this battery as an extra battery for my Gerbing battery heated vest. works perfectly. I am satisfied with it.
after a while didnt hold the charge as long, after i got the battery, but it works even after a deep charge, batteries has it own quirks
this battery does not charge and I want to return it for a new one. I have tried to charge it over night and it does not light up to adjust the heating settings. Please send me a new battery.
This product did just what the company said it would do. I am very please with the performance of this battery.
this is a great battery they last for a long time after charging....thank you so much we are very happy with it
Works very well, and are easy to charge. However, on some items it only lasts a couple of hours -- will need 3 or 4 batteries in rotation for those applications.
I bought two of these as replacement batteries for my original Cabela's. The gloves are lifesavers especially after the really cold Michigan winter we just had. My original batteries were starting to lose their charge after half an hour. The replacements hold it far longer.
Have used mine for two years (30+ times) and still hold a full charge. If you want them to last DON'T just store them all summer and fall. Charge them every month or so to maintain at least a 25 percent charge at all times. Otherwise they WILL fail! Just follow the instructions everyone.
Answer: yes
