I'm getting ready to pull my battery for the winter, and would appreciate some advice for maintaining it during the off-season.
I've heard about using "smart battery chargers" to keep the cells in peak condition without a risk of boil-over or cooking the cells. Unfortunately, I could not find anything in the archives with this title, and a web search has produced more info than I can sort out.
Does anyone have advice as to a preferred brand & specifications I should look for in a unit?

I use 1.5 amp 'permanent mount' (it has a mounting bracket) "Marine Smart Charger" from Schumacher... About $25 at Kragen. Use it year round with my shorepower connection. No complaints over the last 1-1/2 years of service.
I hook mine up to a little Guest 2606 multi-stage portable unit and leave it there all winter. It's the battery that came with the boat four years ago--no idea how old it is, but it's been perfect each year.
Mine stay hooked up to my 2 battery Guest charger at all times. The charger is connected to the Guest battery switch, it is handier than trying to connect it to the batteries themselves.
I have a 25, it is in the port sail locker. Above it is the back of the power wall so the wires simply connect to the feeds of the battery switch. I wanted it outside of the cabin because of the heat it generates.
Left unchargerd for long periods, batteries will self discharge and the plates will become sulfated, ruining the battery. It's also harmful to allow a battery to freeze up which it might do when the charge is low since the acid solution becomes less concentrated due to discharge.
I'm planning on pulling it mostly for the reason that I have not had time to set up a waterproof shoreline power connection & onboard charging system yet and don't want to come back to a dead battery in the spring. (Chesapeake Bay)
Lightnup: I like the concept of a solar charger, but recall something a while back about potentially overcharging the cells with a solar powered unit.
I'll start looking at them, but if all you 12 volt experts out there have advice or warnings on solar panels I'd appreciate hearing them.
