Note
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.
For an SMB board with 3-pole battery contact (RMU101 3HAC044168-001 or
RMU102 3HAC043904-001), the lifetime of a new battery is typically 36 months.
For an SMB board with 2-pole battery contact, 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 for longer production breaks
with a battery shutdown service routine. See Operating manual - IRC5 with
FlexPendant for instructions.

Note
There are two variants of SMB units and batteries. One with 2-pole battery contact
and one with 3-pole battery contact. The variant with the 3-pole battery contact
has longer lifetime for the battery.
It is important that the SMB unit uses the correct battery. Make sure to order the
correct spare parts. Do not replace the battery contact!
