2.4 Battery Operation
The 482-AG can be equipped with an optional internal Lithium-Ion battery to provide up to:
• 40 hours of continuous use (single load cell, 350 ohms, no LCD backlight)
• 15 hours of continuous use (single load cell, 350 ohms, with LCD backlight)
When operated on AC power, the internal battery is automatically charged.
The status of the battery is displayed by an icon in the upper left corner of the LCD display. When operating on battery power,
the icon of the approximate percentage of battery life remaining displays. When connected to AC power, the icon indicates if the
battery is charging or fully charged. The following table outlines the meaning of the various battery icon indication levels.
Battery life depends on several factors, including number of load cells, frequency of use, LCD backlight, options installed,
temperature, and other accessories being used. Battery charge time is approximately 16 hours to 100%.
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
for more information about the sleep mode.
When the battery life reaches 5-10 percent of capacity, the
Lo Bat
flashes on the display. When the battery life is less than 5%,
it will flash faster. At 0% the indicator will turn off. Battery charge time is approximately 16 hours to 100%.

When installing a 482-AG with a battery option, it is recommended that the CPU board jumper 4 on the A/D Board be
removed. See
. 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
for more
information.
