Replacing the Main Battery Pack
Periodically you must replace the main battery pack. FBxConnect provides a battery life indicator to
show the number of days in use. In addition, if you use a lithium battery for main power, the Status
LED shows yellow when the battery is low and needs to be replaced.
WARNING
If lead acid battery voltage falls below 4.7V, the battery can no longer be recharged, and the
charging system considers the battery dead. You must replace the battery.
