Slow Cranking - Battery?

[TOUGEghost]

Another thing to keep in mind is that low voltage and slow cranking will eventually burn up your starter. I know I'd rather just get a new battery than a new battery and a new starter.

And another thing to remember is that an alternator needs a good reference source (AKA: battery) ...that's why when replacing an alternator rule of thumb is to recharge battery to at least 75% of a full charge before starting vehicle. I'm guessing that if OP had his battery tested it'd be down about 100 amps from the original CCA rating on the battery, unless there's an obvious fault such as corrosion build-up.
