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: D34M These batteries are designed for starting and deep cycle 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. |
