Have your battery charged and load tested!! WFCO chargers might not
be top of the line but they work just fine for many folks.
I think you're getting the cart before the horse changing chargers when
you say your battery is bad. You should address that first.
Not knowing your rig and your power usage, we all are guessing.
I can typically go 1 night per battery with the furnace set to 55 when
outside temps are near freezing. I have 2 plain old 12v. If you have
incandescent bulbs in your fixtures you should know they are power
hogs too. Many folks who are trying to extend battery life are changing
to LEDs. You don't need to change them all, just a few in critical places.
Use them when on battery power. I have some in my rig now that
cost me a measly $1 each and they worked just fine last weekend
when we gave them their first test. They use such a small amount of
power I could change them all to LED and turn them ALL on and my
amps draw would be about the same as a single 2 bulb incandescent fixture.
Just my 2¢ Good Luck!
