When was the last time you checked the water level in your flooded batteries? Do you have maintenance free gel cell or AGM batteries instead?


Flooded batteries only- The charger may evaporate the water and you will need to fill or "top" them off. To do this you will need distilled water and I recommend a regulator battery filling jug. This special jug has a spring loaded nozzle. Fill the special jug with distilled water and push the regulator down into the liquid cell. The water will fill to the appropriate level. You will know when the jug has filled the battery to the proper level because the gurgling sound will stop. Be careful because the water in the batteries is actually acid. Wear old clothing and protective glasses in case of splashing.

All Batteries- Grab your battery cables and pull and shove on them to make sure they are secure. Look at all fittings for any corrosion.

How many and what type of batteries do you have aboard? Depending on the size of your boat this can be a large inventory of batteries installed in many locations throughout the hull.
• Dedicated Cranking battery for your propulsion engines.
• Separate dedicated cranking battery for your generator.
• Deep cycle batteries for your house bank and inverter
• More batteries for your thruster and anchor windlass.

Some batteries require special chargers. You may not mix a flooded battery and an AGM battery on the same charger unless it has separate programmable output.

Maintain your batteries so your boat is ready to go when you are. But, if you are not comfortable doing this yet, call Captain Chris and well walk you through your first time. 772-205-1859...Better yet, join us at Introduction to Boat Systems, a hands on 2-day seminar.

Battery jug in action. No guessing about the water level. If you have 16 batteries like we do then you have 48 cells to fill. This gadget sure makes life easier.
