How To Recover Deeply-Discharged Optima Batteries

Recommended Posts

At Fred's request, I'm re-posting this information in this section, so he can sticky it-

 

 

Many of the “bad” batteries returned to us are just deeply-discharged and many battery chargers will not recognize or charge any battery that has been discharged below 10.5 volts. A deeply-discharged Optima can be recharged with such a charger, by using the parallel charging technique explained in this video-

 

 

The key to long battery life is to maintain a voltage level of at least 12.4 volts. When batteries are discharged below that level, sulfation begins to diminish performance and longevity. Selecting the proper battery for your application is also very important. Both RedTops and YellowTops can be used in starting applications, but YellowTops are true “dual-purpose” batteries, designed for both starting and deep-cycle applications. If you are running a winch, refrigerator or other significant electrical accessories, we strongly recommend selecting a battery designed for deep-cycle applications, like a YellowTop. If you have any questions about our batteries, please don’t hesitate to ask.
