what dows ah mean for battery power tools
Amperes. Ah is an abbreviation for ampere-hour, or amp-hour. This the total amount of charge a battery can deliver in one hour. A power tool that continuously draws 1.0A of current will completely drain a 1.0 Ah battery pack in one hour (under ideal conditions).Obviously this means that a 2.0Ah battery pack can power the same tool longer than a 1.0Ah battery pack can, assuming the current flow remains at 1.0A and there are no other differences.asically power tool brands can â and please someone correct me if Iâm wrong â swap in higher capacity cells for lower capacity ones in current battery packs. Change battery cell suppliers or select a different line and whoosh 1.5Ah packs become 2.0Ah and 3.0Ah packs become 4.0Ah. But of course itâs not this simple.
