I'm looking for a recommendation of a battery minder for the Odyssey 680 battery, there is a lot of confusion on what's required for this type. I bought a charger/trickle charger that's for this type only to find out the charger fan runs continuously when plugged in, hardly what I want. As a side note, before I changed to this battery in 2015 the original (at this point) 15 year old Sears tractor battery sat in previous years uncharged all winter (warm storage) no problem. The new Odyssey sat over 2015 winter and was totally dead in the spring, only partially revivable, so I am now on my second and as I didn't get the car out this year but a few times have had to charge it also.
Thanks for the replys.
