How Do You Properly Charge a Dead REDTOP Battery?

Do you have questions about your battery or OPTIMA batteries in general? We have a toll-free number, with people waiting to help- 888-8OPTIMA.

You can also e-mail us at info@optimabatteries.com.

Our first question is from Kevin, who asks, "How do you properly charge a dead REDTOP battery?"

In most instances, an OPTIMA can be treated and charged just like a regular lead-acid battery. 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

By the way, if you haven't visited our YouTube channel yet (www.youtube.com/optimabatteries ), you should definitely check it out. There are a lot of great, informative videos on battery selection, care, and diagnostics.

Our second question comes from Joshua, who asks, "With a dual battery system, is it critical to first disconnect BOTH negatives before moving on to removing the positive nuts?"

For a dual battery system, it's best to disconnect the system negative first, then the combining negative, which connects the two batteries together.

Thanks for stopping by the Power Source, we hope the information we've provided is useful and that you come back and visit us often!
