Description
ABB SB822 3BSE018172R1 Rechargeable Battery Unit
Product Introduction
Controller battery arrangements are easy to overlook during AC 800M maintenance because SB822 is not part of the normal I/O signal chain. The ABB SB822 3BSE018172R1 is an external DIN-rail-mounted rechargeable battery unit designed for AC 800M controllers. ABB specifies a 3.6 V rated output and 0.05 A maximum output current. The assembly includes a lithium-ion battery, a 24 VDC connector, and the TK821V020 connection cable.
For maintenance and procurement, the important point is that SB822 is a controller battery-backup accessory, not a 24 VDC cabinet power supply. ABB’s AC 800M product catalog lists it separately from processor units and other system hardware. The current ABB documentation specifies DIN-rail installation, 85.8 mm width, IP20 protection, and an operating range of 0 to +55 °C. A replacement should therefore be checked against the controller model, battery connection arrangement, cable requirement, and actual battery condition—not simply the physical appearance of the unit.

Application Scenarios & Field Considerations
1. AC 800M controller battery backup
is intended for use with ABB AC 800M controllers as an external rechargeable battery unit. It is part of the controller accessory architecture rather than the process I/O architecture. ABB’s catalog explicitly lists among AC 800M system accessories.
2. Control cabinet battery replacement
The external DIN-rail arrangement allows the battery unit to be installed separately from the AC 800M processor hardware. This can simplify cabinet maintenance compared with treating the battery as an ordinary removable electronic module.

3. Controller maintenance and lifecycle support
becomes particularly relevant during long-running AC 800M installations where battery age, charging behavior, or controller maintenance history is uncertain. The model number alone does not establish the remaining service life of a battery, so an inventory inspection should include the battery’s physical condition and maintenance history.
4. Existing 800xA / AC 800M installations
ABB’s current documentation places within the AC 800M Compact Product Suite and System 800xA hardware ecosystem. It should not be confused with an AC/DC power supply, CPU battery installed directly inside a processor, or a generic 24 VDC UPS.

The distinction between the complete assembly and its replacement battery component is important during procurement. ABB documentation identifies 3BSE018172R1 as the complete rechargeable battery unit, while newer ABB records identify a separate rechargeable lithium-ion battery as a replacement product.
Engineer’s Guide — Field Pitfalls to Avoid
1. Do not treat as a 24 VDC power supply.
The 24 VDC reference in ABB’s description relates to the connection arrangement. The battery unit’s rated output is 3.6 V, with a maximum output current of 0.05 A.
2. Verify the complete assembly versus the battery cell.
, 3BSE018172R1, and the separate replacement battery part number should not automatically be treated as interchangeable purchasing descriptions. Confirm whether the project requires the complete DIN-rail unit or only the internal rechargeable battery.
3. Check the connection cable.
ABB specifies TK821V020 as the connection cable supplied with . A visually similar battery assembly without the correct connection arrangement should not be assumed compatible.
4. Battery age matters.
A warehouse label showing “” tells you the model, not the remaining battery capacity. For used or long-stored inventory, inspect manufacturing/maintenance information where available and verify charging behavior before returning the unit to service.
5. Observe lithium-ion storage requirements.
ABB’s replacement-battery documentation provides specific storage recommendations for lithium-ion batteries, including avoiding deep discharge and maintaining appropriate storage conditions. Do not treat the battery as ordinary electronic inventory.
6. Do not substitute by voltage alone.
A 3.6 V rechargeable battery with the same nominal voltage is not automatically a suitable replacement. The connector, charging arrangement, physical package, chemistry, capacity, and controller interface all matter.
FAQ
What is ABB 3BSE018172R1?
ABB 3BSE018172R1 is an external rechargeable battery unit for AC 800M controllers. It is DIN-rail mounted and includes the lithium-ion battery, 24 VDC connector, and TK821V020 connection cable.
What is the output voltage of ?
The rated battery output is 3.6 V, with a maximum output current of 0.05 A. It should therefore not be described as a conventional 24 VDC power supply.
Is used with ABB AC 800M?
Yes. ABB explicitly describes as an external rechargeable battery unit for AC 800M controllers and lists it within the AC 800M Compact Product Suite.
Does include the connection cable?
ABB’s product description specifies that the unit includes a 24 VDC connector and TK821V020 connection cable. When purchasing a used or replacement unit, confirm that the supplied accessories match the required configuration.
Can be installed on a DIN rail?
Yes. ABB identifies as an external DIN-rail-mounted rechargeable battery unit. Its published dimensions are approximately 85.8 × 58.5 × 136 mm including the hatch.
What is the operating temperature of ABB ?
The current ABB hardware selector specifies 0 to +55 °C. Some older secondary documentation has listed a different upper temperature limit, so the current ABB specification should be used for engineering decisions.
What should be verified before buying an ABB replacement?
Confirm the complete part number 3BSE018172R1, the physical assembly, battery condition, connector/cable arrangement, and compatibility with the installed AC 800M controller. For used inventory, battery condition is particularly important because model-number matching does not establish remaining battery capacity.
