I have a guest 2 bank @ 10 amps. charger on my boat. <br /> My question is, Does anyone leave their charger plugged in ,and maintaining their batteries, during the off season?<br /> Or , do you just plug it in periodically, through the off season?<br /> The guest chargers are not supposed to boil/overcharge your batteries. <br /> I have a friend that plugs his (also a guest) in when season is over . And never unplugs it until spring. <br /> He has done this, for as long as I can remember. He claims to get great life, from his batteries.<br /> Is this a good idea?<br /> Or is it better to plug it in, say once a month?<br /> Thanks,<br /> KYHunter
