Napa Essentials 85-2500 - Manual (Page 13)

120 minutes + 15.5 = 75.5 amp hours
2
(75.5 amp hours) x (0.75) = time = 1.9 hours
30-amp charge rate
Then:
(1.9 hours) x (recharge factor of 1.25) = 2.38 hours or 142 minutes
recharge time.
12. MULTIPLE BATTERY CHARGING
Batteries of the voltage may be connected in parallel for maintenance
charging. Charge time increases in proportion to the number of batteries.
Rate of charge decreases in the same proportion.
Example: Charging 2 batteries in parallel will take 2 times longer; each
battery receives 1/2 the amount of charge showing on the ammeter. Thus,
if the ammeter shows a 30-amp charge, each battery will get a 15-amp
charge (when batteries have the same rating, same state of charge, etc.).
