    trickle charger for the winter

    any suggestions on a trickle charger for the winter?
    recently put my boat to bed and I'd like to keep my batteries tip-top for the next six months.
    also, ever hear of the practice of removing the negative cables from the batteries to prevent extra drain?
    thanks,

    Deltran battery tender has always worked well for me.

    I've seen some guys using solar chargers that

    plug right into your 12V outlet. It's the same as I see some guys use when they park their car in the airport lots for a few weeks. Disconnecting the +/- cables only works to prevent a parasitic drain on your system. You can not trickle charge your system if any of the cables/terminals are disconnected.

    I have used this for a couple of years on my AGM batteries. Works great. I like the desulphator funtion. That is why I bought it over the batteryminder. I charge one battery at a time, switching once a month or so. I have a battery switch so there is no need to disconnect any terminals.

    Like Fixx, I just put it on the trickle charge for a day or so before it goes back in the boat.

    Yup. Mine come out and store in the basement. I put a slow charger on them a couple times over the winter. Why subject them to bitter cold? My original batteries have 6 seasons on them and still load test good so I must be doing something right!

    Battery Tender

    I have used the "Battery Tender" brand of low output chargers that I got from Eastwood Company with great success over the last couple of winters. I use them for both the boat and car batteries. Leaving the battery in the car allows me to use the theft control system without it actually draining the battery.
