I seem to recall that for best battery life you should charge it at
the 20 hour rate. You have a 2000 AH starting battery? [Ten times
the
size of the one on Cat's biggest bulldozer]. Charging a 25 AH
battery
at the fifteen minute rate has to be a poor idea.


Rule of thumb given to me by an old time Trojan application engineer:

Recharge rate = 15% of total connected AH rating of bank.

Based on 2000AH bank, it will accept a 300A recharge rate without
complaint.

Every 100AH consumed requires 125AH replacement.

Yes you can play games with the above, but it will come back to bite
you.

Wet cell battery technology hasn't changed much in the past 100 years,
it is a very mature product.
