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:|
|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)
|Current||Approximate time to 90% charge|
|100 amps||35 minutes|
|50 amps||75 minutes|
|25 amps||140 minutes|
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.
|Shipping and Transportation Information:|
OPTIMA batteries can be shipped by AIR. The battery is nonspillable 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.
The Optima model number for this battery is 34/78. If you are replacing an Optima battery you already have, this model is the same as batteries marked 8004-003, 9004-003, 27990, 34-78, 34/78-980, RED34/78, SC34U, or N9934/78RED.
