Home Forums Hunting & Shooting Hunter's Campfire Truck Battery Replacment Suggestions

I rarely have a battery last more than 30 months in my superduty. The heat here kills them. We also have better luck with wet batteries in airplanes than the much more expensive AGM batteries.

Yep.

The 650-675 range grp 65's will last longer than the typical 850 CCA ones people think they need (and your gear reduction starting system can't tell the difference), even with Ford's excessively high voltage regulators.

Those play a big role in toasting too....

Ford must have finally figured part of this out, as most new diesels I see have 750 or 675 CCA group 65's in them. Still not a cure for a poor system.
