Do not charge, disassemble or burn the battery!
Incorrect use of the lithium battery contained in this device may cause damage
incurred by fire or chemical burns. The battery must not be charged,
disassembled, burned or exposed to temperatures exceeding 100°C (212°F).
The battery compartment holds a 3 V lithium battery, type CR2477N or Z3605,
that supplies the real time clock with power in case of a power failure.
If you want to change the lithium battery during a power failure, make sure that
you have the new battery ready to hand. For a certain time a gold cap capacitor
provides the required power.
At room temperature, the battery has a life span of about one year.
