Maybe someone smarter than I can address your battery requirement. In order to calculate the required times for charging and 'floating' the battery we need to know a few parameters:
A) make/model of the battery, spec's vary from manufacture even for similar types (agm/gell) etc. B) Average temp of the battery room. C) Often overlooked is the length and gauge of the wire to the battery (do you have a fuse inline recommended but adds resistance ?) as even a small amount of resistance will effect change the volts/amps at the battery terminals you need to compensate for this. D) Once you have those parameters set you should be able to calculate the charge rates, the float rates at a minimum. Seems every one has a different opinion as to how best to charge/ float and other things I always like to start with the manufactures spec sheets. You might want to try a product like a superpower gate I have a few and they work great as batteries are rather expensive and not taking care of them properly will mean they either won't be me fully ready for use , or worse have their life reduced. or at least have a 4 stage 'charger' handy , if you happen to have a Astron, there as some articles around the web as to how to modify them to interface w/a battery. What did I forget to mention? Best of luck Myles N2EHG On Jun 7, 2009, at 3:57 PM, Ralph Tyrrell wrote: > > I am using an Alinco DM-330M power supply.
