A system for watering an electrolyte or lead acid battery in which the cumulative amount of water added during each filling event is determined by detecting the amount of water passing from a supply hose to the battery. A fluid dispensing member, such as a direct fill link or nozzle, can be attached to and detached from a single point watering subsystem. A flow detector, such as a flow meter, in fluid communication with the fluid dispensing member can wirelessly output the cumulative water added to specific batteries to an interactive computer application, which can include a wireless component such as a smartphone or tablet communicating with a remotely located interactive database.
