The battery condition information may be used to identify potential low battery conditions, the type of dispenser, the type or form of product dispensed, and/or to detect occurrence of a battery replacement event in a hand hygiene product dispenser. The battery condition information may further be used to determine a number of dispenses remaining for a hand hygiene product dispenser. The battery condition information may further be used to provide battery condition information for battery operated hand hygiene product dispensers in hand hygiene compliance systems. ## Claims ### Claim 1 A system comprising: a plurality of dispensers each configured to dispense a hand hygiene product, each dispenser configured to detect a dispense event and transmit a corresponding dispense event signal including dispenser identification information associated with the dispenser, each of the plurality of dispensers having an associated dispenser type and an associated dispensed product type;
