Replace the RTC Battery
The computers use nonvolatile memory that require a RTC battery to retain
system information when power is removed. The battery is on the computer’s
motherboard.
The battery must be replaced during the life of the computer. The battery life
depends on the amount of time the computer is on, or on-time.
If the computer does not display the correct time and date, replace the battery.
IMPORTANT
We recommend that you use only Allen-Bradley approved replacement parts
and accessories.
Refer to
for qualified replacement part and accessories.
ATTENTION: A risk of fire and chemical burn exists if the battery is not handled
properly.
• Do not disassemble, crush, puncture, or short external contacts.
• Do not expose the battery to temperatures higher than 60 °C (140 °F).
• Do not dispose of a used battery in water or fire.
