How To Determine Battery Amp Hour Rating. In other words it is an indication of how much energy can be stored by the battery. Depends how you look at it You get the picture.
The ampere hour rating is unchanged at 45 Ah. This is known as the C-rate or 1C-rate. If not you can calculate it as Volts x amp hours Ah.
For secondary cells the amp-hour rating provides a rule for necessary charging time at any given level of charge current.
This is usually stated on the battery itself see Image 1. Battery measurements are commonly written out in units of ampere-hours Ah and milliampere hours mAh which represents 11000. Battery AH X Battery Volt Applied load. Starting batteries on the other hand are typically rated at 10Hr rate because they are used faster so.
