A monitoring device 10 has first 20 and second 30 electrical connections for connection to a battery 90 and a power supply 110 respectively, and a monitoring circuit connected between the first 20 and second 30 electrical connections in which the monitoring circuit includes means for detecting a predetermined set of characteristics of the current flow between the first 20 and second 30 electrical connections. The characteristics may be voltage, current, or on and off times. The monitoring device 10 may also detect when a battery 90 is connected to a charger 120, and may record the number of times a battery 90 is connected to or disconnected from the monitoring device 10, and may detect when the recommended practice is not conformed to. |
