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: 34 and 34R
These batteries are designed for engine starting applications. They are not recommended
or warranted for use in deep cycle applications.
Recommended Charging Information:
Alternator:
13.3 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:
Maximum voltage 15.6 volts. No current limit as long as battery
(Constant voltage charger)
temperature remains below 125°F (51.7°C). Charge until
current drops below 1 amp.
All limits must be strictly adhered to.
Recharge Time:
(example assuming 100% discharge – 10.5 volts)
Current Approximate time to 90% charge
100 amps
50 amps
25 amps
35 minutes
75 minutes
140 minutes
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 of charge.
(All charge recommendations assume an average room temperature of 77°F (25°C).
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.
