Abstract
A wet cell battery monitor developed to monitor both electrolyte fluid level and electrolyte fluid charge (specific gravity) of a single cell. The monitor includes a probe and appropriate circuitry. The probe is adapted for insertion into a cell for monitoring and is connected to two circuits which are interconnected. Both include resistors, preferably variable, and include induction coil type relay switches. Blocking diodes are preferably used to maintain the independent integrity of each of the two circuit, one which warns of fluid level drop off and the other of a decrease in electrolyte fluid charge. The two circuits each drop off independenly in response to specific gravity (state of charge) and to fluid level, respectively, setting off alarms, e.g. visual or audio signals.
