Paul,
A lot of advice, some good, some bad, however, I suggest you check a battery manufacturer website for real facts. It seems Jonathan has done some of that with his use of the battery minder. The battery maintainers are the best thing that EVER came on the scene, just a slight bit more expensive than a trickle charger, but oh, so much better. The board thing really is a myth. Fill to proper level, keep them CLEAN, out of freezing temps, and hook a maintainer to them using jumpers, sit back and watch Nascar!
The best thing, however, is to get in it and go!
