Power: 
CCA (BCI 0°F):
800 amps
MCA (BCI 32°F): 1,000 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: 34M 

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: 
(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.


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 35 minutes
50 amps 75 minutes
25 amps 140 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.

Model: 6V 

These batteries are designed for engine starting applications. They are not recommended or warranted for use in deep cycle applications.

Recommended Charging Information: 

Alternator: 6.65 to 7.5 volts
Battery Charger (Constant Voltage): 6.9 to 7.5 volts; 10 amps maximum; 6-12 hours approximate
Float Charge: 6.6 to 6.9 volts; 1 amp maximum; (indefinite time at lower voltages)
Rapid Recharge: 
(Constant voltage charger) Maximum voltage 7.8 volts. No current limit as long as battery 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) 

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.
