I've been having regular problems with batteries in my '85 westy. I've
replaced the battery twice now in 3 months (on warranty luckily). I
checked the alternator and it's giving the right voltage, and nothing
else seems to be draining down the battery. I don't set my fridge to
battery, and the water in the battery seems just fine. I've been using
the DieHard 30042 WeatherHandler which is what came in the van when I
purchased it from the PO.  Is this battery too weak for the Vanagon? I
looked up this battery series online and it says they have up to 700
cold cranking amps, so I don't understand why it wouldn't be
functioning fine (the '85 vanagon requires ~435 cca's right?) to start
up the van. Any clues as to what direction I should take from here?

Thanks in advance,

Dylan
