Napa Essentials 85-640 manual Multiple Battery Charging

10.5CAUTION - Do not leave Manual chargers unattended.

10.6CAUTION: If at any time the battery gets hot (above 125°F (52°C)) or acid comes out of vent caps, STOP charging.

10.7To maximize battery life - Let automatic chargers complete charging.

11.MULTIPLE BATTERY CHARGING

Batteries of the same 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.).
