23.1 Rechargeable Battery Pack
NivuFlow Mobile usually operates with a rechargeable battery pack by default. This ready-to-
use battery pack allows for long measuring periods.

Ready-to-use battery packs are obtainable on order at NIVUS (see chap. “55
Accessories”).
The battery pack is stored in the according battery compartment. An additional battery pack
can be plugged right next to it. Since both sockets are almost equivalent the battery socket
can be selected freely if only one battery pack is used.
•
While Charging only the battery plugged into the right socket is charged however, and
the battery will be charged only up to approx. 75 %.
•
When Discharging the battery with the higher capacity (independent of the socket) is
used until the capacity of both batteries has reached the same level. After that both bat-
teries are discharged equally.
Moreover, the battery type used or the number of inserted batteries should be specified in the
>Battery (12V)< menu to correctly indicate the remaining battery power in the >Sys-
tem</>Information< menu.
The battery compartment is locked with a cover and six non-detachable hexagon socket
screws.
Installation of spare parts/parts subject to wear and tear
The use of spare parts/parts subject to wear and tear (such as rechargeable batteries) not
approved by NIVUS will invalidate the guarantee.
