Does anybody know what's the best battery to replace the original dryfit
battery in an Eurovan 92 ?  We leave for Mexico and our auxiliary
battery is dead.  We bought the van in october and tried it during a
short trip (3 days).  The battery would charge (at least the computer
was saying it was fully charged) but it couldn't keep its charge for
more than a few hours with the fridge on or even only the lights on.
What is the normal autonomy for this battery, with normal use of lights
and fridge?

Last week, we tried to plug it overnight, but it didn't work.  No sign
of life.  The charger below the fridge outputs about 2 amperes.  Could
it be that the battery needs to be plugged for a much longer time ?  Or
maybe I should remove it and use (buy) a stronger charger.

We will buy a battery anyway since we need one for the trip to Mexico
and this wouldn't leave time to fully charge the battery (if I'm right
and it needs a long charge).  I was told a Delco battery would do it.
What's my best bet ?  May be I should buy one that is no bigger than the
original one since, if the original still works, they both could fit in
the battery area and I could plug them in parallel.  Or is it better to
buy a bigger one and use only one battery ?

Any model to suggest me, at a reasonable price ?

Thank you,
