    Will be gone for 4 months soon. Would like to connect a trickle charger to the battery but it would be unmonitored for the 4 months.

    Are there such chargers that are safe for 4 months without being monitored? If so, specify maker and unit would help

    That's a long time for an electrical device to be left unchecked.
    I just had a LED night light catch on fire, lucky I was there, it was smoking & smolding pretty good, who knows what could have happened????????????

    I would ask a buddy or relative if possible to do it at their house!!!

    If the battery is in good shape, I'd just disconnect it and leave it. It should last like that no problem.
    I use the battery tender also, but I don't think I'd leave it unattended for four months. You just never know for sure...

    A good battery should last 4 months unattended. When you get back, put a trickle charger on it for 24 hours before starting the car. That should top it off for use.

    That Battery Tender might be good to put on a battery for long term use, but I can't confirm that because I have never used one. I have an Exide brand tender, and the first winter I tried leaving it on my battery, it killed my 1 year old battery completely in a few months. Since then, I put it on the idle batteries for 24 hours one day a month, and my batteries now last me 10 years or more. So, that bad experience has made me no fan of continuous trickle charging on a battery.

    I would pull the battery out and store it "unconnected" in a cool dry place.

    Have had two tenders on two batteries for two years with no issues. Have about 6 total and the others are plugged in fro Nov to May. No problems with those over the past several years.
