Note:

Data above is for 1.215 nominal specific gravity. Batteries are offered in 1.215 and 1.250 specific gravities. The amps @ 1.250 specific gravity are equal to the amps @ 1.215 multiplied by 1.10. For batteries with 1.250 specific gravity, use indicator "C" with battery type. For example: XT-4LAC-7 identifies 1.250 specific gravity. XT-4LA-7 identifies 1.215 specific gravity.
