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 |

I'm sure you've cleaned the battery terminals and posts already. right? =-)
a dying battery will hold "voltage" but not carry a "load". you need a battery load tester. a harbor freight load tester has been in service at my house for several trouble free years. and at $17.00 it's hard to beat the price. http://www.harborfreight.com/cpi/ctaf/Cate...4&pricetype |
