Subject:	SGP/EBBR - EBBR E4 Data Incorrect When Batt. Volt. Under 10.4 V
DataStreams:	sgp30ebbrE4.b1, sgp15ebbrE4.b1, sgp5ebbrE4.b1
Description:	All data was incorrect when the battery voltage dropped below 10.4 volts. An old battery was the cause of the problem; it had no deep cycle charge capacity.
