With 80% depth of discharge, you can only use 80% of the battery''s total rated capacity. So, for example, in a battery with a battery capacity of 100 Ah, you can use up to 80% of the battery capacity, or 80 Ah, before you need to consider recharging the battery. What is depth of discharge in batteries?
Current, or amps, must be known before calculating amp hours. Current is a stream of charged particles, including electrons and ions, in motion through an electrical conductor or void. An amp hour represents the number of amps that move in one hour. To illustrate, a battery with a capacity of 150 Ah could discharge 150 amps in a single hour or ...
When comparing battery capacities, such as 4.0 Ah and 6.0 Ah, the higher Ah rating indicates a larger capacity. A 6.0 Ah battery has 50% more capacity than a 4.0 Ah battery, meaning it can provide longer use time under the same discharge conditions.
In the case of discharges over 10 hours, the discharge capacity is determined by dividing the battery capacity Ah by the current value drawn. For example, if a 100-Ah battery is discharged with 10 A, its voltage drops to 13 V immediately at the start of discharge, and after supplying energy for 10 hours, its voltage becomes 11.3 V.
