charging battery on toad

I tow a Matrix and am wondering if it makes sense to use a battery charger to keep it charged along the way. It has to be set on ACC for it to be towed and the battery dies after a few days. I have had some luck running it each night for 10-15 mins. and/or unhooking and driving it after a few days of towing,but want to avoid all that. I was reading about the NOCO Genius chargers but am still confused about which one I'd need. Thanks,Meg

  • I have to start my toad around every 250 mile per owners manual.

    Haven't had a dead battery in 6 years of traveling. Never could understand all the posts about dead batteries, running charger wires etc etc.

    That is until the one time when I was I was close to my destination and blew off the 250 mile start. Arrived......with a dead toad battery. Didn't realize that my starts for the trans also charged the battery. :S

    Sooo "I" know for a fact that if you start it for 5-10 minutes every 250 miles, when you stop to rest or fuel up, it keeps the battery charged! :B

    I'm surprised at how many of you have toads that you do not have to start them to keep the trans oil cool. Baring the ones that have installed disconnects.

    If you examine what all comes with the Toad Charge, you will find you get a lot more than a length of wire and fuse.

    You need more isolation than just a fuse. Otherwise current will feed back into MH from toad.
  • If you have a 6 or 7 pin electrical connector on your MH you could simply run a wire from that hot connection to the TOAD and then through a diode and 20 amp fuse and then connect directly to TOAD battery. The TOAD will be charged anytime the MH engine is running and the diode will prevent reverse current from the TOAD to the MH. Probably $20 in parts

    For about $110 the toad charger will do the job. OR, you can mount a diode in a plastic box that does the same thing for about $6
