The battery low alert (38213 Battery charge low ) is displayed when the battery needs to be replaced.
The recommendation to avoid an unsynchronized robot is to keep the power to the controller turned
on until the battery is to be replaced.
See the replacement instruction for more details.
iv The battery low alert (38213
Battery charge low ) is displayed when remaining backup capacity
(robot powered off) is less than 2 months. The typical lifetime of a new battery is 36 months if the
robot is powered off 2 days/week or 18 months if the robot is powered off 16 h/day. The lifetime
can be extended with a battery shutdown service routine. See
Operating manual - IRC5 with
FlexPendant for instructions.
