COACH BATTERIES

[Ron Thompson]

I can't help but comment on this one.

Old and new batteries mixed would most likely have eddy currents flowing between the batteries due to deterioration of th internal currents and would definitely have reducing effect on the AH and therefore the cranking amps too.

There are good points on both sides of this discussion. No need to beat each other up.

Oh by the way my qualifications are over 30 years experience electronics with an engineering background. Not a graduate engineer but definitely schooled in several good engineering schools. In summary I was a practical applications electronic tech.

Just my two cents.

Why??? Please use science, physics or electronics or references.

It is very likely that the manufacturers design almost all 6 volt
batteries to withstand more abuse like 100% discharge, temperature
extremes and vibration. However if you get a 12 volt battery
from the
same manufacturer, built to the same design spec and use it in the
same application, the 12 volt system will last longer and outperform
the 6 volt with less maintenance.
