new battery losing power

[jeddiepines]

I just bought my 1991 Maxima a couple of months ago. Its been running great until a week ago when the battery went dead. I purchased a new battery and in about 3 days it lost its charge. I replaced the new battery with a better brand and the same thing happened. I checked the altenator with a multimeter and it showed 13+ volts, telling me that it was charging the battery. Any idea's on what to do next would help.

thanks

i should have said this in the first message, the 3rd battery that i bought started to go dead as well. im charging it about 3x a week to keep a charge above 12+ volts.

Your Altenator isn't charging. You should have about 14.5 Volts. 13 is to low. Turn you headlights on and I bet you drop below 12.

something is draining the battery. I don't think it is the alt. but you never know, you need to check the charging system.

Most likely there is a drain somewhere. Also, check your battery cables and clean them and the battery posts. Good Luck!!

do u have a high powered muzic system? that might be it also, but not so quick, id'e say the altenater, especially if u have a high powered system.
