I took my 1996 firebird formula out Saturday night and got home and around 3. Sunday morning I went out to start it around 11 a.m. and the battery was complietly dead. But nothing was left on. I plugged a battery charger on and it started up after a few minutes of charging and ran great. I used it a few more times that day with a few hours in between. And it started right up everytime. Then I parked it later that night. Then Monday night I went out to see if it would start and when I turned the key it lite up like normal then as soon as I went to start it the lights on the dash flickered and it was dead. But once again the charger got it started and then started a little bit later again fine as well. Could this be a short or just a bad battery on its way out? I believe its is a 550 amps battery with 450 cca. And every where I looked it said that was smalled then the factory one. And its cammed so it should need more amps to start. Any ideas would be great! Thanks!
