The Siemens 6ES7288-5BA01-0AA0 is a SIMATIC S7-200 SMART SB BA01 Battery Board that provides compact battery-board support for the CPU real-time clock.
- SB BA01
- Battery board for supported real-time-clock backup
- Installed in a compatible S7-200 SMART CPU signal-board slot
- 35 x 52.2 x 16 mm
In an S7-200 SMART automation station, it supports the real-time clock of a compatible S7-200 SMART CPU through the documented battery-board interface. It works with the exact CPU, expansion-bus or signal-board interface, wiring, field devices, and project configuration specified for the complete article number. It is applied in time-stamped machine events, scheduled operations, maintenance clocks, and retained calendar functions.
Important Notice: Use the complete 6ES7288-5BA01-0AA0 code and verify the physical nameplate, current Siemens documentation, signal range, wiring, project, and accessories before installation or replacement.

Important Notice: These are two separate Apter Power documents prepared from the manufacturer-published Siemens information named in each document. Confirm the physical nameplate, current Siemens documents, and host-system requirements before installation or replacement.
Real-time-clock support
Supports the compatible CPU clock through the documented battery-board interface
Time-based automation
Helps retain the clock basis used by scheduled machine functions
Event chronology
Supports time-stamped events where the CPU program and clock configuration provide that function
Maintenance timing
Applies to time-stamped machine events, scheduled operations, maintenance clocks, and retained calendar functions after CPU compatibility is verified
Read the exact Siemens S7-200 SMART documentation before use. Verify 6ES7288-5BA01-0AA0, SB BA01, host system, signal type, wiring, and project from the physical installation.
1
Identity: Match every character of 6ES7288-5BA01-0AA0 and the SB BA01 marking to the physical nameplate and project
2
Host: Verify that the exact CPU and firmware support 6ES7288-5BA01-0AA0 before fitting the board
3
Battery handling: Follow current Siemens polarity, replacement, storage, transport, and disposal instructions; do not infer a battery type from appearance
4
Installation: De-energize the CPU, use the documented signal-board slot and orientation, and refit all covers before service
5
Commissioning: Set and verify the CPU clock, confirm the required backup behavior, and document the service date
