3.1 Battery Capacity
Battery capacity is expressed as Ampere-hour (Ah), which is the product of
discharged current and the discharged time in hours.
Discharge rate is indicated by C/t, C is the nominal capacity of the battery, t
is the discharge time.
The nominal capacity of the sealed lead acid battery is a capacity using 20 hour
discharge rate. For example, the capacity of WP5-12 battery is 5Ah,
when the battery is discharged with C/20 rate, i.e., 0.25 amperes,
the discharge time will be 20 hours.
The battery capacity is varied with the discharge rate. The larger the
discharge current, the smaller is the battery capacity. The relation between
the battery capacity and the discharge rate is as follows:
The information about the discharge current or power within specific
discharge time of our regular or high rate types sealed lead acid batteries
products are available through our product specification catalogues.
The temperature influences the battery capacity. The relation between the
capacity and temperature is as follows:
The battery capacity may be also expressed by discharge power (Watt),
which is the available discharge power within 15 minutes.
