Dual batteries ?

Recommended Posts

Any one done this? I want to add another one for my lights and the radio.

I was looking at getting a battery isolator from Checker auto for like $35. Will this work?

Yes it will work, but depending on where the alternator regulator picks up it's sensed voltage, which is probably internal, the isolator (assuming it is solid state) will cost you about .7 to 1.2 volt depending on load. Another method would be to use 2 relays that get their pull in power from the the alternator, One heard of one disadvantage to relays and that was when one battery is dead, you start for a short time and turn off, during that time the dead battery sucked most of the life out of the good one. Only heard of this once.

With the recent development of the schottky diode, that would be the way to go. It only has a forward voltage drop of about .3 to .5, very acceptable.

PS, If you want to make your own for around $10, PM me.

Thanks for all of the info Kinarfi! Once I get ready too do it, I'll let you know. But I got a lot bigger issue to deal with now.

      Bought this machine a couple years ago and the gages didn’t work.  I have troubleshot this thing numerous times to no avail. Thought it may be a common ground so I individually grounded  the gages, didn’t work.  I have tested the sending units.  All have some resistance that changes as the engine revs or gets warmer.  Please help me.  Thanks in advance

      Hello,
      I have changed the battery , alternator and the regulator.
      I have the red battery light on indicating it is not charging.
      Is there something else that could be the problem to my battery not charging??
      Thanks
      Bill

      I have checked that the fan operates if you bypass it, I have checked the fuses, I have checked the relays but the fan does not come on and overheats. Has anyone had this experience. HELP!!

      I am trying to figure out the type of battery that I should get for my 2013 Cub Cadet Volunteer.  The old battery says it was 450 CCA, but I've been having trouble finding one with exactly that in the local stores.  My wife picked up a 575CCA (26R) from OReillys.  Will that work?  Or will I ruin something by increasing the CCA?
       
      The attached image is of my old battery.
