Charging Problem

Im kind of going through the same prob. See if the battery needs some water, and then put it on the charger for a couple of hours. Usually your car should run without the batt, connected. Im only getting like two startups from my battery and then I have to charge the crap out of it, I put a little more acid in it today and then some water, and its on the charger right now so it should be good in the morning, ill have to check out the alternator thing also to make sure my alt. is good.
These might apply to you............

I would put a voltmeter (handheld digital) across the battery terminals. Note voltage with the car off. Then start the car and note the voltage. Now check voltage at the alternator charge cables (assuming a 2G). If they are the same, your alt and/or its wiring would seem problematic.

Check and recheck all connections and wiring (it gets old and corroded or vulcanized) at the alt, solenoid and battery.

If not dice above, though not as feasible is: the parts store can test the system dynamically. Should your battery take a flying poop while you're there, most stores will charge it back up. Otherwise, simulating the heat conditions or considering a wiring issue can make it difficult to track down.

Good luck.
