Battery maintenance
The battery is a 3-cell Lithium polymer type with a capacity of 1Ah and a nominal voltage of 11.1 V.
Lithium batteries has a longer life when stored at the nominal voltage (50% charged), so we try to keep this when robots are not used.
Lithium batteries will be destroyed or damaged if discharged below 3.2V per cell (9.8V).
The build-in charger is of different types (internally), and some of then discharge the battery, when not charging. They discharge with between 0.5 to 5 mA. i.e a fully charged battery is drained after between 200 and 2000 hours.
After charging a battery with a leaky charger, remove the charge cable as shown in figure below.
Figure 1. Some of the chargers destroy the battery when unused for a period of time, so on most robots the charge cable is disconnected. Reconnect to charger when needed.
