Recommended Charging




The following charging methods are recommended to ensure a long battery life:

(Always use a voltage regulated charger with voltage limits set as described below.)



Model: D34

These batteries are designed for starting and deep cycling applications and for use in vehicles with large accessory loads.






Recommended Charging Information



Alternator:

13.65 to 15.0 volts

Battery Charger:

13.8 to 15.0 volts; 10 amps maximum; 6-12 hours approximate

Float Charge:

13.2 to 13.8 volts; 1 amp maximum (indefinite time at lower voltages)

Rapid Recharge (Constant voltage charger):

Maximum voltage 15.6 volts. No current limit as long as battery temperature remains below 125°F (51.7°C). Charge until current drops below 1 amp.

Cyclic or Series String Applications::


14.7 volts. No current limit as long as battery temperature remains below 125°F (51.7°C).  When current falls below 1 amp, finish with 2 amp constant current for 1 hour.
