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: D34/78 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. All limits must be strictly adhered to.
