I thought it would be interesting to compare how fast the DeWALT DCB115 chargers a battery compared to the DCB118 “fast” charger. In the video we charge 2 DeWALT 5ah batteries side by side to find out how long it takes each charger to give a full charge. The DCB115 is a 4 amp charger and the DCB118 is an 8 amp charger. DeWALT also has a 2 amp charger, it is model DCB112.
Below are the current prices (as of 6/2/19) for the DCB118 and DCB115.

Maybe discharge the batteries again and re do the test after switching the batteries to account for possible differences in the charging capacities/condition/age of the batteries? Average the two charging times?
