What all can battery power

[ngranneman]

What all is the battery meant to power for the RV? I initially got it and used the battery to use the lights and used it to do the slide in several times and upon charging it it was 50 percent discharged and didn't know if this could possibly damagne the slide motors or anything else I am not aware of?

Na, won't hurt the motors, when the battery gets much lower, the slides just won't work.

Batteries control some lights, water pump, furnace, Refrigerator circuit board, power tongue jack and more, depending on what you have.

Are some things in your coach not working the way that you would like them to? Do you think that you are using more battery power than what the battery that you have now can supply?


A 50% discharge is about as far as you want to go if you want the typical lead acid battery to survive a number of charge and discharge cycles. If you are within that range, and the battery is supplying all you need, then you are fine. If you want, or need more, let us know. There are all kinds of solutions to increasing battery reserve.

Battery on a TRAILER runs the break-a-way braking (emergency) system
Battery on most all RV's runs
Lights
Furnace
Fans
Water pump
Slide out motors
Jacks if electric
And control power for the Fridge and Water heater
Can also run control power for the A/C if it has a wall mounte or remote control T_Stat
(If it has knobs on the ceilin it uses no 12 volt)
If you have an evaporative cooler. that's 12 volt.

IT can also run TVs Radios and in facct everything else if you have enough battery and enough inverter.

A good size battery bank will run an AC for 15-30 minutes is all though.

Plug in and get the battery charged!  This can be plugging in the camper or just running a cord to a car battery charger.  Even if it is just a 120V  15A power supply with cord adapters, leaving the camper plugged in all the time keeps the battery charged and everything should work as expected - EXCEPT the A/C!
