Optima battery permanent damage?

I bought red top battery years ago and I guess it died and was left without being charged in a car for a bit. Since then it just wont hold charge like it should(damaged cells?) I've charged it numerous times and left it on trickle charger but I took a load tester and it just dies under load tester.
Is there way to bring it back to like of should I just stick with lead battery?
I think optimas are overrated.

You might be able to get it to take a charge by connecting in parallel with a regular lead battery, then connect both to your charger....good luck.

If it wont hold a charge, it is dead.

It is holding a charge, however if I try to start a car with it and keep cranking for a few times it will loose charge. It shows as being fully charged according to multimeter but as soon as I put load tester on it, it will start to die.

Anything special I should do or just hook up to regular 12V battery charger?

Just regular charger, the problem with the optima batt is the voltage comes up before it takes a good charge which backs down your charger, jumping with a regular batt will keep the charger working. I brought mine back this way, I put charger on 2 amp setting and left it overnight.

My charger is not automatic so it will charge until battery blows up if I forget to unplug it
I will try to parallel charge it, hopefully it does work.

I have a 12V yellow top Optima that reads 3.8V and refuses to take a charge. Is it salvagable? I've tried the good 12V battery in parallel trick with no success.

Take a look at the Optima website - plenty of info on how to revive these batteries.

I have used a Ctek 3300 to pull these batteries back to life. Before giving up, it might be worth finding a shop that has the right charger to try and charge it for you.

Thanks. I had been using a slightly different technique than described. I'll give it a try again. My smart charger is comparable to the Ctek you use.

Hello, I noticed your conversation involving our batteries and wanted to offer some assistance. mitmaks, how long ago did you buy your battery, how long did you leave it sitting in a discharged state and what was the voltage when you measured it with your multimeter after fully-charging it? hduff, how long has your battery been sitting at 3.8 volts?

The parallel charging technique everyone is mentioning is explained in this video- Tech Tips 3: How do I recover a deeply-discharged battery? - YouTube The issue is that some chargers will not recognize or deliver current to any battery that has been discharged below a minimum voltage threshold, typically around 10.5 volts. To add to the confusion, some chargers will turn on and operate for a brief period of time, but shut off if voltage doesn't reach a certain level within a certain timeframe. That can make folks believe the charger did charge the battery, even if that wasn't the case. The parallel charging technique allows those chargers to see the voltage level of the fully-charged battery (it doesn't matter if it's flooded or AGM) and then deliver current to the deeply-discharged battery.

I used the parallell charge technique on a yellow-top that had been sitting discharged at 4 volts for about a year. I'm using a Schumacher SSC-1500A charger and can only get the battery up to 12.0 volts. Any hope for my 5yo Optima battery?

Testing with a multimeter will tell you nothing unless you check the voltage when it is under a load as in cranking. Willing to bet the voltage falls way off during cranking. The battery is dead, move on. FWIW I also think Optima batteries are over rated.

Jim, thanks for taking the time to help, great customer service. I have been satisfied with my optima and plan on buying another for my next ride.

Larry, I'm happy to offer assistance wherever I can. Vince, while a load test would be ideal for any battery, most folks may not have the ability or equipment to perform a load test. Even some of those who do have the ability to load-test a battery fail to first attempt to properly-recharge the battery, resulting in a false result. However, anyone can pick up a $12 multimeter and determine what the state of charge is on their battery. That is a great place to start, as many “bad” batteries returned under warranty are just deeply-discharged and work fine, when properly-recharged. We just dropped 100 of those returned batteries into Chumpcars last weekend at Road America and they worked great in some very demanding applications.
