one too many batteries? mostly bored ramble

[ander]

hi all,

anyone have a creative use for the (originaly placed) house battery that never gets used?

i have a 94 pleasure way that came with the usual rv/starter house battery charged from the alt or on shore power.

over the past year iv added 200 watts of solar with 2 6volt batteries.. this system is seperate from the stock sys right now and runs everything in the rv. and only recharges from the solar..which works fine.

the original house battery just sits there..charging from the alternator and waiting for me to think up a cool use for it.

i keep thinking ill pull it out to save weight etc. but thats not a big issue.

i had thought of using it as a spare emergency starting battery...but unhooking and replacing or running the big cable back up front killed that idea for now.

and i cant really combine it with the 2 6volts

anyone have a interesting idea for this odd man out? or should i just pull it and use the space for a safe or hideyhole?

enough rambling..thanks
ander

If you keep the battery in place you can use a jumper across the isolator posts for emergency battery boost.

Eight foot only, but 10ga wire. Many cheap booster cables use 10 and 12ga wire. They work fine in normal (summer) conditions but when it's 40 below and you need to crank with some frozen oil you might as well just give up lol

Short answer. Yes it would work.

You could make a temporary connection to let the good battery "charge" the low battery then remove the jumper before cranking the engine.
