That is perfect! Thanks I'll be sure to use that tip.

Just a tip here - IF you end up getting a new battery, consider switching from the factory size (78 = side terminals) to a 34/78 which has both side AND top terminals. Just gives you more options to attach the battery to power.

AFAIK there's no significant price difference between a 34/78 and a straight 78 so if you're replacing the battery anyway, this is a zero-cost modification.

I am running 2 34/78 batteries on my Suburban and have come to really appreciate the top terminals.

Got one. Great for charging the battery.
