What does 5 ah mean in a battery?

Lead Acid Battery Amp Hours (AH) Specification Defined. The Amp Hour (AH) specification provides a measurement of battery capacity. A typical Amp Hour specification might read, “100 AH @ 20HR”. The specification is saying that the battery will provide 5 amps of current at a useable voltage continuously for 20 hours.

What does 4.0 Ah mean?

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).
