Question

What is the reserve capacity of battery?

(a) Time for which the battery can supply 25 A at 80℉ with minimum cell voltage 1.75 V

(b) The current which the battery can supply continuously for 30 seconds with minimum cell voltage 1.2 V

(c) Lasting power of a battery on a small load

(d) Rate of current for 20 minutes with a minimum cell voltage of 1.5 V

Answer 1

Right answer is (a) Time for which the battery can supply 25 A at 80℉ with minimum cell voltage 1.75 V

The explanation is: The reserve capacity is the time for which the battery can supply 25 A at 80℉ with minimum cell voltage 1.75 V. It is the measurement for the total capacity of the battery.
