Optima 34 Red Top

Enquire Now

The OPTIMA Red Top™ starting battery significantly outperforms and outlasts conventional flat plate batteries. The SPIRALCELL design uses high purity lead plates wound with a glass mat that absorbs electrolyte like a sponge. This design gives the OPTIMA battery extremely high power, very low internal resistance and other features that translate into the following benefits: 

• Provides years of reliable, convenient performance. High purity lead design provides a much longer shelf life, meaning the OPTIMA battery can sit unused for up to one year and still start your vehicle.
• Completely sealed - Because of the unique design you can mount it in almost any orientation and you'll never have to add water or check fluid levels, making your OPTIMA battery maintenance-free. Your OPTIMA battery is also classified as "NONSPILLABLE" -making the battery safer for people, equipment, and the environment.
• Delivers high power output both faster and longer than conventional batteries, resulting in greater cranking ability and less capacity reduction at high current loads. The low internal resistance enables the OPTIMA battery to recharge faster than other batteries.
• Delivers high power output both faster and longer than conventional batteries, resulting in greater cranking ability and less capacity reduction at high current loads. The low internal resistance enables the OPTIMA battery to recharge faster than other batteries.
• Extremely resilient to heat and cold - tests prove that the battery performs better in all temperature extremes than conventional batteries.
• Maximum vibration resistance - the SPIRALCELL design provides unequalled vibration resistance for all your off-road, commercial, and heavy duty industrial needs.

Suggested Charging Rates:

Alternator: 13.8 to 15.0 volts

Battery Charger
(Constant Voltage): 13.8 to 15.0 volts, 10 amps maximum,

Float charge: 13.2 to 13.8 volts, 1 amp maximum current

Rapid Recharge: (Constant Voltage Charger)
Maximum voltage 15.6
No current limit as long as temperature remains below 125°F
Charge until current drops below 1 amp

Recharge time (examples assuming 100% discharge - 10.5 volts)

Approx. 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.
