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.)
These batteries are designed for engine starting applications. They are not recommended or warranted for use in deep cycle applications..
Recommended Charging Information
||13.3 to 15.0 volts; no amperage limit
||13.8 to 15.0 volts; 10 amps maximum; 6-12 hours approximate
||13.2 to 13.8 volts; 1 amp maximum current (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.
(example assuming 100% discharge – 10.5 volts)
||Approx. time to 90% charge
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 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.
Shipping and Transportation Information
