Built-in Level Indicators
Each AquaPro fill cap’s built-in level indicator tells whether the particular battery cell needs water or the electrolyte level is OK.

Internal Water trap
The integrated water trap protects against explosive transmission of oxy-hydrogen gasses from one cell to another through the water hose system. (Verified by German battery company Hagen, Research results available on request).

Durable Polycarbonate Body
AquaPro is made of polycarbonate. This high quality material is more impact and temperature resistant than the cheaper polypropylene used by most competitors.

Self-closing Hydrometer Access
The self-closing hydrometer access allows one to insert a hydrometer without opening a cover that could break, get lost or be left open. The maximum diameter of the fill-tube is 3mm (1/8”).
