Test your truck battery and check its cables

[Paul in Idaho]

Thanks everyone for your replies, especially the tips on testing.

When I got all the corrosion cleaned off I found the terminal is cracked in 1 spot and broken through in another. Replacing that component will be the next project.

My jumpstarter is the same NOCO unit as @LuketheDog linked to. It worked great.

wow, can’t imagine even trying to run a battery 7 years no matter the performance.

I have a on board battery tender from noco, my truck doesn't move much and the 5x2 charges and keeps the batteries in good shape. Now if I didn't do that, I'd probably have had to change them by now.
