hi all, new guy on here , would like to pick your brains please. bought a new dewalt 18v cordless drill it came with two 4ah batteries from Screwfix. out of the box both batteries lit up only 2 bars out of 3 max so i charged both of them up for over an hour on the charger
one now reads 3 bars full charged reading but the other battery still only reads 2 bars
what would you do?
