14 480 Legend Series
2.4 Battery Operation
The 480 can be equipped with an optional internal Lithium-Ion battery to provide up to:
• 18 hours of continuous use (single load cell, 350 ohms, no options)
• 15 hours of continuous use (four load cell, 350 ohms, no options)
When operated on AC power, the internal battery is automatically charged by means of an internal battery charger circuit.
Battery life depends on several factors, including number of load cells, frequency of use, options installed,
temperature and other accessories being used. Battery charge time is approximately 16 hours to 100 percent.
To extend battery life, the indicator features a sleep mode that allows the indicator to go into a low power mode
while it’s operating on battery power. See Section 9.6 on page 65 for more information about the sleep mode.
When installing a 480 with a battery option, it is recommended that the CPU board jumper 4 be removed.
Removing jumper 4 will maximize the life of the battery when the indicator is turned off due to reduced
standby current. See the Power parameter in Section 3-8 on page 31 for more information.
When the Standby parameter is set to any setting other than NONE, any key press will work to wake the
indicator from standby.
