Re: battery swap???

This grainger page:

For that part number says it’s a "deep cycle" battery (as opposed to a starting battery, right)?
And says it has a reserve capacity of 90 min.

This page:
https://www.pacificpowerbatteries.com/a … cfaq4.html

says:
To convert Reserve Capacity (RC) to Ampere-Hours at the 25 amp rate, multiple RC by .4167

So 90 x 0.4167 gives 37.5 Amp hours??
