I have a red top Optima battery in my 74 and over the last few months, the engine has been turning over slower and slower. What are the characteristics of the Optima when it is going bad?
Lead acid batteries usually just dump and won't start the car. I haven't checked the voltage at rest or while the engine is running to see if it's the battery or my charging system. I guess that will be tonight's activity. Can I use an external charger to try to put a full charge on the battery? Thanks, Spoke |

Yes, you can use a 2 amp trickle charger on an Optima. I put one on the 914s periodically during the winter.
1. Clean your battery posts. 2. Clean & tighten your negative cable ground, transmission strap ground & starter connections. 3. Start your car. Use a multimeter and check the voltage reading while the car is running (charging voltage). Should be about 12.9-13v. Someone will give the correct "book" figure, I'm sure. If you're not getting the proper charging voltage, the regulator could be suspect, but I'd clean the alternator mounting points first. It's a far cheaper solution.
