Re: Cold Weather Battery
The 6-year old cheapie battery that was in the truck when I bought it, is doing something similar. A 10 minute charge will get the engine started, and the alternator will charge the battery to 13.2 volts, and it will even start on its own the next day. But after a couple days the battery voltage has dropped to around 10 volts. Current draw is a just a couple milliamps, so the problem is simply a very old battery that won't hold a charge very long.
Doesn't get much cheaper than this! Amazing that it lasted 6 years.
