O 1800 PLUS Series units are equipped with the
SmartLED battery status system. The SmartLED
system lets you know when the unit is charging and
when the charging is complete. It also gives you a
status on how much charge is remaining in the battery
during use, when it needs charging, and when the
batteries will need to be replaced.
