MULTICAL® 403

10.2 Lithium battery, 1 x D-cell
In order to obtain the longest possible battery lifetime MULTICAL® 403 can be fitted with 1 x D-cell lithium battery
(Kamstrup type 403-0000-0000-200). No tools are required in order to mount or replace the battery module. The
lithium content of the battery cell is approx. 4,5 g, which makes the battery subject to regulations on transportation
of dangerous goods, see document 5510-408_DK-GB-DE.
The battery lifetime depends on factors like ambient temperature and meter configuration, an indication of battery
lifetime is thus a realistic estimate.
10.3 Lithium battery, 1 x C-cell IoT
For particularly current-demanding applications such as the battery operation of NB-IoT modules, a C-cell IoT
(Kamstrup type HC-993-06) must be used. This battery package includes a lithium C-cell and a special capacitor that
helps the battery to deliver high pulse currents.
