Napa Essentials 85-521 Battery Charger User Manual

10.5 CAUTION - Do not leave Manual chargers unattended.
10.6 CAUTION: If at any time the battery gets hot (above 125°F (52°C)) or acid
comes out of vent caps, STOP charging.
10.7 To 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.).
12. CHARGER FEATURES AND CONTROLS
12.1 OPERATING INSTRUCTIONS
Once the unit has been properly connected to the battery(ies), plug in
the charger to AC power. Initially all 4 LEDs on both charging banks will
turn on in sequence. The battery charger will perform a self test and light
the two yellow LEDs in sequence next. The charger will then go into a
battery diagnostic mode to determine if the battery(ies) are independent
or connected in series (24V) or parallel (12V). NOTE: Itisimportanttonot

diagnostics are complete, the charger will begin charging the battery(ies)
if needed. Each bank has an independent display of LEDs and will show
the charge status of the battery. NOTE: Whenbothoutputleadsare
