I just picked one up at the local Rural King store. 975 CCA, 685 reserve, 2 yr warranty $129.00 and core (I've got plenty of them). Tomorrow it goes on the test bench to see how it holds. If its satisfactory then I'll change out more as needed.


That seems like a very reasonable price. I just bought a new lead-acid
for my truck (the original finally gave up the ghost). Got it at
AutoZone for $158. 1000 CCA.

The tractor doesn't need anything that big. AutoZone carries the AGM
batteries as well, so I'll check them out.

I noticed something interesting after I replaced the truck battery.
It seemed to have more pep .. or maybe just more response to the
throttle. Shift points were different also. Then I realized that the
truck computer was re-learning my driving habits. I normally drive
like an old lady, rarely exceeding 3,000 RPM when accelerating. So,
after 7 years, it apparently had adjusted the timing and shifts
accordingly.
