OPTIMA REDTOP CHARGING INFORMATION
The following charging method. are recommended to insure a long battery life -always use a voltage-regulated charger, with voltage limits set as described below. RedTop Type 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, no amperage limit. Battery Charger: ● 6.9 to 7.5 volts, 10 amps maximum 6-12 hour approximate. Rapid Recharge: ● Maximum voltage 78 volts (regulated), no current limit as long as battery temperature remains below 125°F (51.7”C) Charge until current drops below 1 amp. Float Charge: ● 6.6 to 89 volts, 1 amp maximum current, time indefinite (at lower voltage). All limits must be strictly adhered to. Safety Information: ● Always wear safely glasses when working with batteries ● Always use a voltage regulated battery charger with limits set to the above ratings. Overcharging can cause the safely valve. to open and battery gasses to escape, resulting in premature failure These gasses are flammable! You cannot replace water in sealed batteries that have been overcharged Any battery that becomes very hot or makes a hissing sound while recharging should be disconnected immediately. ● Failure to fully charge a battery can result in poor performance and a reduction in capacity.
How do I charge a deeply discharged battery? The same parallel charge instructions work for both the 6 volt and 12 volt OPTIMA, But you will have to use a 6 volt charger and connect in parallel with a 6 volt battery. You will still use the 10 AMP setting If an OPTIMA is deeply discharged (below 10.5 volts) most basic chargers will not supply a charge Also keep In mind an OPTIMA will not recharge properly If treated as a regular flooded or gel battery To charge the battery, you can wire a second fully charged automotive battery (12+V) to the discharged AGM in parallel (+ to + and - to -) Then hook up the charger to either battery, setting the charger at 10 amps Leave for two hours, monitoring frequently During this process If the discharged battery gets very hot or if it is venting (hissing sound from vents) then stop this process immediately. When the discharged battery reaches 10.5 volts or more, remove the standard battery and continue charging the AGM until fully charged. For normal charging a relatively low current, such as one or two amps can work well, but when the battery has been deeply discharged, some sulfation of the battery plates may have occurred. If you charge at 10 amps, the higher current will help to break up this sulfation. If you have an automatic charger, let it run until the charger indicates charging is complete If you have a manual charger, you can get a rough estimate of the charging time in hours of a completely discharged battery (11.2V) by multiplying the capacity (amp hours or Ah) of the battery by 1.2 If your battery is not completely discharged the time would be less.

In most cases these steps will recover the AGM battery It’s okay for the AGM battery to get slightly warm during the charging process. If it’s hot to the touch it means there’s a short and the process should be discontinued.
Can You Trickle Charge An OPTIMA? And what type of charger can I use?
Yes and you can use any charger on an OPTIMA as long as the voltage is regulated properly. If your charger will remain on indefinitely, the voltage should be at 13.8 volts maximum with a one amp maximum current.
