Top­ping up the bat­ter­ies blind

Canal Boat - - Back Cabin: -

I have three deep-cy­cle flooded bat­ter­ies for do­mes­tic use. Top­ping up the cells with dis­tilled wa­ter is a real pain be­cause the bat­ter­ies are tucked up un­der the semi-trad deck.

Is there a gad­get you can pop into a cell and add wa­ter to the cor­rect level by touch/sound with­out be­ing able to see the level? I know Tro­jan do an au­to­matic wa­ter­ing sys­tem but it is too ex­pen­sive.

ARI­ADNE, via the CB web­site TONY REPLIES... RS com­po­nents ( http://uk.rs-online.com) sell an au­to­matic top-up bot­tle, but I have no idea how good it is. If the back deck of the boat is steel and you have side lock­ers, think about cut­ting out the sec­tion above the bat­ter­ies in­side the locker and re­plac­ing it with Hex­a­grip board so you get bet­ter ac­cess.
