I'm trying to avoid the cost of trading in the old battery and
purchasing a new battery each summer.

First, I would suggest that something is wrong with the charging
system in the PWC if you are having to replace batteries every year.

Secondly, wiring it to the truck in parallel wouldn't be a good idea
for a variety of reasons including over charge, unequal charge, etc.

Third, get a "floating" charger rather than a constant "trickle"
charger. The floating charger will turn itself on and off as the
battery requires over winter. You don't really need to remove it from
the PWC - just unconnect it from the PWC (leave it in), hook the
charger to it and plug it in. Unless, of course, that isn't
convenient - in that case just remove it, put it somewhere you can
plug in the charger and let it sit over winter.

I use three floater units on my Ranger over winter and haven't had a
failure yet.

Unless you count the time I left the key and radio on, but that was
Scott's fault. :)

I thought (between the words I can't spell) you told me it was because
you set the battery on a concrete floor. At least you noticed (tested)
before we wet the hull
