How to Determine Amp Hr Rate
For deep cycle batteries the standard rating is 20 hours. So, if a battery has a rating of 100AH @ 20Hr rate, then that battery was discharged over 20 hours with a 5 amp load. Starting batteries, on the other hand, are typically rated at 10Hr rate, because they are used faster, so the 20Hr rate is not as important.
Battery Amp Hours
The amp hour rating of a lead acid battery will depend on its size and capacity. For example, a typical car battery might have an amp hour rating of 50-60 Ah, while a marine battery might have a rating of 100-200 Ah or more. Lithium-Ion Batteries.
