Note: When an IMR with a fully discharged battery is connected to power via its USB
cable, it may display a white battery error indicator. This is normal behavior while a fully
discharged battery is charging to a minimum voltage, at which time it should follow the
states shown in the Power indicator LED table. Wait several hours while the battery
charges and you should eventually see the power LED turn solid red, indicating it is
charging, and finally solid green, indicating that it is fully charged and ready for use. If the
white LED never turns off while the IMR is connected to power, the battery is likely bad and
must be replaced. This will need to be done approximately every 300 to 500 charge cycles.
See Installing a Replacement Battery on page 35.
