“It makes things easier to have a charged back-up ready when the first battery runs down! Battery life is pretty much as promised, with 4 plus hours at high and up to 8 hours at low.”
“While my older (and larger) rechargeable batteries still function wtih no issues, it is still good to have the newer/smaller versions on hand. I immediately notice less of a bulge on the left side of my waist when putting the vest on. Also the battery lasted much longer than the older version. This is easily a win/win for me. Highly recommended.”
