So you go out one day and your car or pickup battery barely has enough oomph to crank the engine, so you head down to your local battery place, where they test it (either by load-test or capacitance tester), and while it has 12+ volts, it fails the test. That’s because automotive batteries fail a load test when their CCA falls below (or fails to return to within) something like 75-80% of their rated value. That means that the 650 CCA battery in your automobile will test as needing replacement when its CCA goes below 488. And around here they charge you $3 for disposing of the old “dead” battery (grr!)
BUT think about this: most atv, lawnmower, motorcycle, etc batteries are rated at 60-130 CCA when new, so that old car battery with “only” 400 CCA is still head-n-shoulders above a brand new $30-40 battery!
Plus in my experience, they tend to last a LOT longer than the tiny atv/motorcycle batteries - because they’re built far better, and they’re now living in a MUCH nicer environment than under a car hood.
So the next time your car battery lays down and dies, don't be in such a hurry to get rid of it - it may well be an awesome battery for your kart, mower, whatever!!!
Keep in mind that automotive batteries are larger and heavier, which just means you’ve got another opportunity for some great diy fun mounting it!
Of course, if it dies because of an internal short, broken terminal, or something like that, it's truly dead and should be sent off to battery heaven.
