The following table lists and describes acronyms and terms used in this guide.
Term/Acronym
Description
Ah
Amp-Hour is a unit of measure of charge that can be stored or delivered to/from a battery.
Battery
One or more cells which are electrically connected together by permanent means, including case,
terminals and markings. Also, the ALM 12V7 s-Series battery.
BMS
