Battery Capacity Chart:

Note
The load current and the minimum voltage varies, depending upon the capacity of the battery, and should be taken from the sticker on the heavy discharge tester, or taken from the chart:

Note
If the minimum voltage is too low after a load period of 5 to 10 seconds, the battery is discharged or faulty; check the specific gravity

If the battery is colder than room temperature, the voltage under load will be lower than the specification.

If battery must be tested cold:

Battery, removing/installing

Some early production vehicles are equipped with batteries 190 mm (7.5 in.) in height. Later production vehicles are equipped with batteries 175 mm (6.9 in.) in height.

Batteries with a height of 190 mm (7.5 in) are no longer available. If battery replacement is necessary, replace the 190 mm (7.5 in.) battery with the 175 mm (6.9 in.) battery.
