Relocating starting batteries

[skippers_1]

i WOULD LIKE TO RELOCATE THE 2 starting batteries to the area under the bed to make room for 2 more 6 volts.
They are sealed and I would be using battery boxes.
Can I extend the cables or do I have to get new ones made its about 6 feet or so.
Thanks, Rich

Even though they are sealed, they will gas when they receive a high charge. I would never put batteries in an interior space.

Get new cables - trying to extend them just adds another place for corrosion to interfere.

I would share Norm4015's concern about moving the battery inside. Even a sealed, valve regulated battery can gas under extreme conditions. And when you say "sealed", to you mean an AGM or Gel type valve-regulated battery? A standard "maintenance free" type of wet cell is not really sealed - it gasses under normal charging. It is definitely not safe for interior use.

Don't know if you have room but on my coach I relocated the batteries to the engine compartment right behind the motor. I was lucky in that all the cables were long enough to reach the new location and only need two short cables to tie the batteries together. I then added 4 more batteries and now have 8 - 6 volt for the coach.

I agree inside the coach would not be a good place to relocate the battery.
