Abstract: 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.

Abstract: The present invention is a state of charge monitor to aid in choosing the correct battery when changing batteries. The present invention is battery based instead of charger based. A monitor unit is mounted on each battery and is wired to measure the voltage on a certain number of battery cells. By monitoring this voltage, a microcontroller in the unit can tell if the battery in use, under charge or completed charge. The microcontroller has programming allowing it to add timers to each state event to make sure a true transition has occurred and not just a transient voltage. The microcontroller will then indicate the state of the battery, so that a user can determine which batteries are suitable for use in an exchange.
