battery maintainer hookup

Recommended Posts

steve-wis

Hi,

I bought a new battery charger that has a built in maintainer.  It is for one battery.  I have two batteries that I would like to keep a trickle charge on.  Can I hook the two batteries to each other, and then the maintainer to one of the batteries to do both?  If I can, would this be pos to pos and neg to neg?

Any info is, as always, appreciated!

How many amps is the charger?

It is possible, but you have to note that the amperage is split between both batteries. So if the charger is 1.5a that means it would put out .75a to each battery which is not enough.

If it is 3a then it would be 1.5 per battery which may be enough to top them off. That is figuring that both batteries are in the same state of health. If one is new and the other is old then it still may not work properly.

positives go together, negatives go together

Easiest route would be to use 2 trickle chargers.

I do trucks and buses which usually have 3 batteries.

So a 60 amp charge in theory charges 20 amps to each battery. Hope this helps

Both batteries are in good shape.  The one gets drained low because I have electric lift and the transplant engine only has a single circuit 2 amp alternator, which can't keep up.  The other one gets drained because the voltage regulator is shot and I don't want to change it till warm weather comes.

The charger/maintainer is 3 amp so I am thinking it will do the job.

So is it positive to positive and negative to negative?

      Hello glad I got on this site. I hope to upload a couple of photos of my Simplicity Broadmoor 
      Model 707 Tractor. I have replaced all the belts on it and installed a new ignition switch.
      Have a mower deck which was in poor shape , repaced a couple of bushings and welded the
      deck where there was some holes. The tractor and mower deck came from a friend and the 
      mower deck metal was getting pretty thin. Some new metal was put in it and we also undercoated the underside of the deck. This was done by my friend Greg Toulman.
      I have not put the mower deck on the tractor yet, waiting for Greg to come home and give me a hand. Can you please tell me if there is a manual for the mower deck and where I could get one.
      I would also like to get some moon wheel discs as well.
      I will try and down load some photos of the tractor when my wife shows me how to. 
      I really love driving this tractor and also how well it is made compare today's tractors, especially the flexible rear end and the rollers.
      Tell the next time 
      Paul
