Now I recall a post or two about the batt terminals being reveresed,
as UCrew posted...but, I also recall other posters using the 49 series
for 3.0s. As primetime wrote, I would skip WallyWorld and hit an
Autozone or Batteries Plus or a lil' more quality/car parts oriented
joint. I would still do an overnight slow/trickle charge to slowly
bring new battery up to full, but that's just me.
If you need pics/DIY link, let us know...
