Bought Mobil warming vest years ago. The original batteries finally pooped out. Ordered replacements. Easy transaction.

I think my original batteries may have been losing charge quicker, so I purchased these as a spare set. They seem to work as well as the originals when new. I like that they have a small cord for the vest and charger to plug into. This makes it easier to stuff them into the vest pockets after they have been plugged in.
