Post Subject: Batteries

I have 3 deep cycle flodded batteries for domestic use. Topping up the cells with distilled water is a real pain as the batteries are tucked up under the semi trad deck. Does anyone know of a gadget that 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.

The cheapest is an automatic top up bottle or maybe they still make tops to fit an ordinary bottle. Have a look at tic-battery-filler-bottle-3226.html but I thing you may have problems getting the bottle into the confined space. Googling "Battery top up" also brings up tery-filling-systems but I have no idea of cost or if they have any products suitable for our typical domestic batteries. If this means the back deck of the boat is all steel I would be thinking about cutting the section above the batteries but inside the side locker out and replacing with Hexagrip board so you get better access. If you have no side lockers it might be an idea to just think about moving the batteries to sit on deck and build a side locker around them. Not ideal but OK for a narrowboat. I just wish that boat builders would follow the BMEA codes of practice and fit batteries in a readily accessible position.
