Always use a voltage regulated charger with voltage limits set as described below.
Recharge optima red top battery.
Optima redtop charging information.
In this 2 part video i demonstrate how to revive deeply discharged optima battery s that will no recharge in a conventional way.
A deeply discharged optima battery less than 10 5 volts will not test or recharge properly if treated as a gel battery or regular flooded battery.
The following charging methods are recommended to ensure a long battery life.
Optima batteries are among the most trusted and popular automotive batteries on the market.
A handheld electronic battery tester will most likely provide inaccurate results.
These batteries are designed for engine starting applications.
One of the great things about optima s agm style batteries is their extremely low internal resistance.
Basically the starter skims off some electricity from the battery for starting and it s rapidly refilled once you start up.
They are not recommended or warranted for use in deep cycle applications.
Why are the optima chargers different or better than others.
These batteries are designed for engine starting applications.
An optima battery has the benefit of very low internal resistance which allows high amperage output as well as efficient charge acceptance.
6 65 7 5v no amperage limit.
This benefit also allows an optima battery to run longer than its specified ratings and run at a lower voltage than typical.
6 9 7 5v 10 amps max for 6 to 12 hours.
What is the optima chargers digital 1200 12v performance battery charger and maintainer.
Starting batteries are designed to be discharged a little then be charged up fairly quickly by your charging system.
Charging optima redtop batteries.

However when batteries are discharged below 10 5 volts many battery chargers will not recognize or charge any battery.
Optima batteries can be recovered from such a deep state of discharge by using the parallel charging procedure described in this video recovering a deeply discharged battery.
Digital 1200 are the optima chargers and maintainer easy to use.
In most instances an optima can be treated and charged just like a regular lead acid battery.
