Smart battery packs
Smart battery packs are equipped with an integrated circuit
which stores information (such as manufacturer, serial number,
production date etc.) and monitors the current battery status
in terms of discharge rate, predicted remaining capacity,
temperature, voltage etc. The battery packs supplied with the
DW2-UPS-250-DC (3 items) are even capable of displaying their
charge state without a separate device. The 5 segment LCD
charge level indicator is always active unless the battery is in
shutdown mode.
