Battery Tender for the Toys

With dune season quickly approaching in So. Cal. I pulled the quads and RZR out this past weekend and had three dead batteries. An overnight charge brought them back to life but I need to figure out the best way to keep all three on a battery tender during the off season. What do you guys do or use? Can one tender be hooked up to three batteries at once (with a little custom wiring) or should I get individual tenders for each battery? Does a tender need to be on all the time or would a few hours per day via a timer do the trick? Thanks in advance.

    I started using Tender Jr's 15 years ago and haven't had to buy a replacement battery since. When not out running, my stuff stays on a tender.

    I would just buy one tender and cycle it to a different battery every few weeks. Physically disconnect the batteries from the ATV/SxS and no reason it can't sit for a couple of months with a charge on it and not drain.

    I also looked at the multiple bank batt tenders but the price seems crazy since the wall wart style are much less expensive even for several of them. I was told those multiple back style are designed for places that need to charge or stock lots of batts all the time like batt stores.

    You can get battery tenders with multiple banks for charging more than one battery up to 10 I believe but they arent cheap.

    A battery tender is intended to be left on all the time while not in use. It monitors the voltage on the battery and will automatically switch between charging and storage modes.

    As far as hooking up multiple batteries to one tender I've never heard of anyone doing that or if the unit will function properly in that situation. May want to contact the manufacturer to see if its OK.

    I buy the simple wall wart ones and keep them plugged in all off season. You can get them for around $20 shipped off ebay. I usually park them in my toyhauler and plug them in inside the hauler. I then plug the hauler in and wala no dead batts. I don't think daisy chaining them together will work and you risk over charging and even a fire if one batt goes bad since the charger will just keep trying to put juice in it because of the other batt connected.
