BLACK+DECKER Battery Pack

So far, this battery has held its charge for days - a big improvement over the battery it is replacing

9 hours to charge 5 minutes of strong output 15 minutes of smacking grass around Don't waste your time or money. I have 2 batteries and they can't keep up. My lawn is about 1200sq feet and it takes 2 batteries to get the trim. Waste of money.

Bought a 18 v chain pole saw for light duty pruning. Batteries require 4 hour minimum change time but only last 5-10 min under use. May try replacement with the 2.0 version of the battery (one at a time).

I can't understand this famous company like black&decker. I bought a grass cutter with these batteries. But even I charged more than 10 hours every times, it last 2 minutes with strong force, then 5 minutes with useless power. I can't understand how did this famous company sell this kind of product? I can't trust this brand name of black&decker anymore.

Less than 1 year ago purchased a cordless trimmer with 2 batteries neither of the batteries will hold a charge long enough for approximately 10 feet of work.
