(25 amp discharge, 80°F (26.7°C), to 10.5 volts cut-off)

Power:
CCA (BCI 0°F):
900 amps
MCA (BCI 32°F): 1,125 amps 

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: D31A

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 (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 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 3 amp constant current for 1 hour.


All limits must be strictly adhered to.

Recharge Time: (example assuming 100% discharge – 10.5 volts)

Battery recharge time will vary according to temperature and charger characteristics. When using Constant Voltage chargers, amperage will taper down as the battery becomes recharged and a full state of charge will be near when amperage drops below 1 amp. 

(All charge recommendations assume an average room temperature of 77°F (25°C). You should always wear safety glasses when working with batteries.)

It’s important to stay safe when working with batteries and you should always use a voltage-regulated battery charger, with limits set to the above ratings. Overcharging batteries can force the safety valves open, resulting in the release of highly flammable battery gases. It also isn’t possible to replace water in sealed batteries that have been overcharged.

Note: You should always disconnect batteries at once, if they become very hot during charging. Not fully charging a battery can result in poor performance and a reduction in capacity. 

Current Approximate time to 90% charge
100 amps 52 minutes
50 amps 112 minutes
25 amps 210 minutes

Shipping and transport information:

OPTIMA batteries can be shipped by AIR. The battery is non-spillable and is tested according to ICAO Technical Instructions DOC. 9284-AN/905 to meet the requirements of Packing Instructions No. 806 and is classified as non-regulated by IATA Special Provision A-48 and A-67 for UN2800. Terminals must be protected from short circuit.
