Hi RHF,

Was reading through the info you had given and had a question regarding
the 55-805000 Battery Charger. Is this device for charging a battery
through the AC current in one's home? I had been looking at the
Xantrex 1500 (http://www.xantrex.com/web/id/63/p/2...24/product.asp)
because it seemed really convenient in this regard (chargin' it from an
outlet at home; no danger of overcharge, etc.). The price, however, is
pretty steep for the Xantrex ($270 or so from these boating sources).

Best,

Junius

For that kind of money,you can buy a big enough solar cell and let the
Sun recharge that battery.

Junius,

Yes this Battery Charger simply 'plugs' into
the standard 120 Volt AC Wall Outlet.

Looks like a Wall Wart with a Pair of Screw Terminals
to connect the DC Output Feed Wires going to the Battery.
