I would think the Cold Cranking amps should match.
3 days??? So if when we have weather like we have had the last week and I take the truck and park the car it's not going to start when I decide to use it again?? or what about vacation? Am I going to have to carry a spare battery with me so I can start the car at the park and ride? That sucks. Might as well get a marine battery then. my parents leave there boat for weeks at a time and it allways fires right up.Originally posted by: Morph
I agree with PuckPuck, if your car sits for more than 3 days at a time, you will also need to invest in a good trickle charger ($60-$80) because the battery will drain and niether jumping nor the smaller cheap chargers, will ever be able to fully charge the battery.
After a lot of frustration and trial and error, I bought a Schumacher 10/2 Amp Fully Automatic battery charger from AutoZone which has a maintenance free deep cycle setting that is perfect for the yellow-top. Like PuckPuck said, just remember to use the 2 Amp setting. Mine looks exactly like the one in the attached pic, except mine says 10/2 AMP and does not say 12/24 volt.
