NOTE: Disconnect supplied devices from the DW2-UPS-250-DC output when they are powered
off! Store the batteries separately if the system is unused for more than two weeks, other

From time to time, due to the aging process of the batteries, it is necessary to recalibrate the battery in order to retain
the accuracy and reliability of the charge level indicator. This can be archieved with an external battery charger (BAT-
CHARGER) which is optionally available. Another advantage of the BAT-CHARGER is that additional batteries can be
recharged without being in the measurement unit. This allows the measurement unit to run non-stop without being
connected to the power net, thanks to the hot-swap capability of the battery packs.
