The BatteryMinder float charger is meant to be left on the battery ALL THE TIME! That's what it's designed for! It constantly pulses the battery to ensure sulfation doesn't occur. Read up on them, you'll be surprised! I get 5 years or more out of my riding lawnmower 1 year batteries with no problems using one that's left connected to the battery any time the mower isn't in use - summer and winter.
They never boil any of the water out of the batteries. It sounds like Rupert isn't knowledgeable about "Float" chargers. They don't taper down when the battery's full, they stop charging and monitor the battery till it needs another boost.
I guess I didn't fully explain, what I meant was that you don't have to stay connected all the time but it is good to periodically connect the charger to bring the battery up to full charge. I have been using a Battery Tender for many years and it stays connected all winter.
