The battery ought to be replaced after 10 years’ normal operation, or after 1 year without mains connection. The type number of the backup battery is 66-99-619. The voltage of a lithium battery is almost constant throughout the whole lifetime of the battery (approx. 3.65 V). Therefore, it is not possible to determine the remaining capacity by measuring the voltage. The battery cannot and must not be charged and must not be short- circuited. Used batteries must be handed in for approved destruction, e.g. at Kamstrup.6 Operational check
