ok I am pretty sure i know the answer but here goes. This year i am renting a storage place to park my boat. It's closer to the lake i fish and saves on wear and tear and gas. Put i am faced with one problem. How do i charge the batt's? I would like to just plug the charger in and leave it for a week but thats probably not a wise thing to do is it? Anyone have any suggestions about my small problem? It's a little 2 bank MK charge in my boat.

bring your batteries home and charge them there

If it is an automatic charger leave it plugged in. I have one on mine, and I plug it in as soon as I get back and unplug it when I'm heading for the lake. Set it and forget it. If it is an on-board charger it probably is automatic-designed to be plugged in all the time. It charges the batteries then maintains them as needed.

Welcome to the forum, BTW!

All of your onboard chargers are designed to plug in and leave them.   Don't try this with those little $30 chargers though, even if it does have automatic shut off.  If it's one of newer Smart Chargers or Intelli chargers they are designed to plug and leave them just like your onboards.

Another option is to charge the batteries to full charge before taking it to storage and then connect a Battery MINDer or similar battery maintainer.  These work great for maintaining a battery but are usually too small to charge the battery.   I think Wal-Mart sells the Schumaukers for less than $20.  The BatteryMINDer high frequency is about the best but cost approx $45 for the 1 amp model but over an extended period of time it will get rid of the Sulpation that almost all marine batteries suffer from.
