When we changed out our batteries 2 8Ds they were 7 year old NAPA batteries.
I figured if they held for 7 years I would invest in a new set of NAPA batteries so
I talked to the manager at the local Napa store and got a pair of 8D batteries for
$350 plus tax. I've known the manager for over twenty years so got a good deal.
These batteries are rated at 1300 CCA each.
