95 Blazer 4.3

Got this truck that needs a little jump everytime I turn it off. So I have this battery charger that I can hook up to the battery and charge it up, but regardless after I turn it off it still needs a little jump. Any idea what it could be? I left it on for about 45mins and it didn't die. I was going to take it to autozone but am afraid it will leave me somewhere on the way.

 

Just settle it and get a new quality battery & GET your alternator tested asap, or you could test it for yourself with a OHM meter,just start engine and put the leads to battery it should read very close to14.4 volts.

 

thanks for the info, the battery is from Feb 07 so its about 1yr5months old. ButI am still going to get it tested, chances are I could have gotten a bad battery maybe I can exchangeit since it has a 2yr replacement warranty. [:-]
