Carlos,
This is a timely topic. I think my 10yr old 12v batt is crapping out.
FWIW, I have an
Interstate Mega-Tron-26 only because it fit my batt box. It has less than 600 CCA.
Although the battery is smaller than the original 6v, the terminals touch the
batt hold down bracket so I had to make one.
Buy
this one if $$ is no object and you want to period perfect.
Will you please tell us what battery you finally purchase and why. I may follow suit.
Thanks,
- Lonnie
