You want to know what the use time in hours for a specific load 5 amps?
But battery specs are not listed that way
RC minutes at 25 amps is the only direct comparison between batteries
The 20 Hour discharge rate is different for each battery
Only UPS Type batteries normally list different amp and wattage use time factors in there specs
Example AGM Telco server batteries,
And they can handle very high amps draw, but are not true deep cycle to be repeately taken to low SOC and I try to keep my overnight use to no more than 30% and preferably less
