Recommended Charging:

Alternator: 13.65 to 15.0 volts
Battery Charger (Constant Voltage): 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 50°C (125°F). 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 50°C (125°F). When current falls below 1 amp,
finish with 2 amp constant current for 1 hour.
All limits must be strictly adhered to.

Recharge time will vary according to temperature and charger characteristics. When using
Constant Voltage chargers, amperage will taper down as the battery becomes recharged. When
amperage drops below 1 amp, the battery will be close to a full state charge.
(All charge recommendations assume an average room temperature of 25°C, 77°F)
Always wear safety glasses when working with batteries.
Always use a voltage regulated battery charger with limits set to the above ratings. Overcharging
can cause the safety valves to open and battery gases to escape, causing premature end of life.
These gases are flammable! You cannot replace water in sealed batteries that have been
overcharged. Any battery that becomes very hot while charging should be disconnected
immediately.
Not fully charging a battery can result in poor performance and a reduction in capacity.
