Hi All

Lauren your original question as spawned an interesting discussion.

What has been peoples experience with the Optima batteries concerning the following:

Post corrosion

Charging rates encountered on the CMPs with the High Amp charge rate regulators

Good high grade regular batteries seem to last 4-5 years in my trucks and then one day they just seem to stop holding a charge. Or their cranking voltage drops off steeply. One of the problems I have noticed on the last couple of batteries is that though they will crank the engine over for a long time they drop below about 4.5 volts very quickly like 20-60 seconds. This is a problem because below 4.5 v the ignition spark is pretty weak.

Cranking time to start is really important if the carb is dry and you have only a mechanical fuel pump.


Cheers Phil
