ABB SB822, article number 3BSE018172R1, is an external DIN-rail rechargeable lithium-ion battery unit for ABB AC 800M controllers.
- Product type: Rechargeable external battery unit
- Article number: 3BSE018172R1
- Controller family: ABB AC 800M
- Battery chemistry: Lithium-ion
It supplies battery backup to a compatible AC 800M processor so controller memory can be retained through loss of normal controller power; ABB specifically states that SB822 is the only external battery available for PM891. The unit uses a 24 V DC charger connection and delivers a rated 3.6 V battery output with a maximum output current of 0.05 A; it is not an analog or digital process-signal module. SB822 is installed with its included 24 V DC connector and TK821V020 connection cable in AC 800M control cabinets where rechargeable CPU-memory backup is required in process, power, water, manufacturing, and other industrial control systems using a documented compatible controller.
Important Notice: Publish or supply only when both SB822 and 3BSE018172R1 are confirmed on the ABB record or physical nameplate.

AC 800M memory backup
Maintains the documented controller battery-backup function when normal controller power is interrupted.
PM891 external battery
Provides the external rechargeable-battery option that ABB identifies for PM891 processor units.
Rechargeable backup architecture
Supports AC 800M installations that require a rechargeable external battery instead of relying on a non-rechargeable external or internal battery arrangement.
Industrial control cabinets
DIN-rail mounting supports documented AC 800M cabinets in process and factory control systems, subject to enclosure, ambient, wiring, and controller-compatibility checks.
Read and follow the current ABB documentation and host-equipment instructions before work. Verify the complete physical nameplate and system configuration.
1
Verify the complete SB822 and 3BSE018172R1 nameplate and the target AC 800M processor documentation before installation.
2
Do not confuse the 24 V DC charger connection with the 3.6 V rated battery output.
3
Use only the documented TK821V020 connection cable and the ABB-specified controller connection; do not substitute an unverified cable or polarity.
4
Keep the unit within 0 to +55 °C and install it in an enclosure appropriate for its IP20 protection rating, G2 corrosive-atmosphere classification, and Pollution Degree 2 specification.
5
Before battery service, disconnect the TK821V020 connector and 24 V supply connector, remove the unit from the DIN rail, and use the ESD precautions in the current ABB maintenance procedure.
