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: D27F
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. |
