Battery Life Indicator
The battery life of 20 hrs apply for rechargeable nickel metal hydride (NiMH) batteries. Disposable
alkaline batteries will provide approximately 10 hrs of battery life. Also with disposable batteries, there
will be a tendency for the life indicator to remain fully illuminated for most of the battery life and only
drop down to the lower levels when the batteries are nearly exhausted.
The SC-1 will slowly deplete batteries even when it is turned off. Fully charged batteries will be
exhausted in about 100 days when the device is left turned off. For long term storage, remove any one
of the three batteries from the device to prevent this slow drain.
