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 Iâm 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 itâs not this simple.
Best Answer: An AA battery (pronounced [double a] or /ËdÊbÉl eÉª/) is a dry cell-type battery commonly used in portable electronic devices. The AA battery type was standardized by ANSI in 1947, and is designated E91 by DIN and AM3 by JIS. Internationally the IEC designated it as LR6 (alkaline), R6 (carbon-zinc), KR157/51 (nickel-cadmium), HR6 (nickel-metal-hydride), and FR6 (lithium-iron-disulfide). Other names include MN1500 and HP7. In China it is known as the #5 battery. In Germany it is known colloquially as Mignon. An AA battery is composed of a single electrochemical cell. A AAA battery (pronounced triple A) is a dry cell-type battery commonly used in portable electronic devices.
