Correct Answer - Option 3 : Internal resistance, voltage, ampere-hours
Concept:
Battery RatingThe most important in understanding the battery specifications are current and capacity.
Current is the strength of the electricity discharged by battery underuse, and it is measured in amperes, commonly referred to as amps. However, the battery’s rating is based on its capacity, which is measured in amp-hours (Ah).
The rated capacity of any battery expresses the average amount of current it releases over a period of time under normal use. This means that a battery with a rating of 200 Ah can deliver 20 amps of power at a constant rate for 10 hours.
Other Battery Specifications
In addition to current and capacity, batteries have several other specifications, including the following:
Energy capacity – The energy capacity of a battery is measured in watt-hours (Wh), and it is calculated by multiplying the watts discharged by the number of hours.
Cycle life – The cycle life of a battery is the number of times it can be fully charged and discharged before its performance slows or fails. The actual time a battery will last depends upon the depth and rate of the cycles.
Charge voltage – The voltage of a battery when it is charged to full capacity is its charge voltage.
Conclusion:
Option 3 is correct.
