VB726U 7v 2600mAh Extra or Replacement Battery

As a senior with arthritic hands and the related Reynaud's syndrome, warm hands while shoveling / plowing is important to me. I bought these two batteries to replace a single broken one, where the terminal contact just inside the battery opening had somehow broken loose and would not engage with associated cables. Your seemingly proprietary connection system for both charging and wearing is very difficult to engage for someone such as me. The release tab is fussy, the opening to insert the wired connector is small, and apparently the male contact terminal susceptible to breakage. Because I paid a lot of money for these gloves just two years ago, I chose to buy more batteries rather than discard the gloves. But your battery design doesn't provide confidence for longevity or ease of use.

so far ok but the vest seems to go off after a short time

Love your product. Thanks

Work great and glad to have backup batteries while in the field

Very happy with the batteries, got to test them right away. I thought I had a bad set until I reread the instructions. For these batteries, you have to 'turn them on', by pressing and holding the power button. Once I figured that out, they worked great. I wanted a backup set of batteries in case my primaries run out of juice, which hasn't happened yet, but you never know.
