I have a 2004 356 which includes 4 lead acid batteries. Three of the batteries are located between the two main stringers... starting from the genny going aft to the bulkhead is A) genny battery, B) Port engine start, C) Stbd engine start, and finally, the 4th battery (the house) is up on a shelf above the Stbd engine start battery. If you have a 355, 356, or similar you understand the location of these batteries and the difficulty of trying to maintain them. Thus, my question, how do you do it?

Using all my best contortion efforts I can barely see the Stbd engine battery and the house battery is just about impossible to service unless it's disconnected and "brought out into the light". Taking a cell reading, watering (without over filling)... how do you do it? I'm a live aboard and I have to top off at least monthly and I'm getting too old for this task so I'm hoping to find out a trick or two that, hopefully, I've missed along the way.

Note: I've researched the auto watering systems and as far as I can tell they won't work as they require all batteries to be on the same level. Since the house battery is my biggest problem, and it's on a shelf above the others, the solution doesn't seem viable.

Thanks captains... fair winds.
