Product Introduction
ABB SB822 3BSE018172R1 is a DIN-rail mount rechargeable battery unit for AC 800M controllers in System 800xA setups. It provides backup power to retain process data and configurations during power loss.800xahardwareselector.automation.
Connects via TK821V020 cable to the controller’s 24 V DC supply for charging. In plant outages, it holds RAM contents for hours depending on load—critical for DCS uptime in batch or continuous processes.
Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| No backup during outage | Dead battery | ✅ High | Measure 3.6 V DC across output with Fluke 115 loaded to 0.05 A | Charge 24 hrs on 24 V; replace if <3.0 V |
| Controller alarms low battery | Failed charge circuit | ✅ Medium | Check 24 V at input connector pins 1-2 | Verify external PSU steady; inspect cable TK821V020 continuity |
| Rapid discharge | High memory load | ❌ Low | Monitor controller current draw <0.05 A total | Reduce active tasks; check AC800M load profile first |
| Won’t charge | Open fuse or diode | ✅ High | Continuity test internal path; insulation >10 MΩ to ground | Bench charge test; scrap if no current flow |
| Corrosion on terminals | Humidity exposure | ❌ Low | Visual check DIN rail area IP20 rating | Dry out, clean contacts; add enclosure if >60°C |
Snap photos of connections, voltage readings, and controller diagnostics before support call. PSU glitches cause 60% of these faults.

Frequently Asked Questions (FAQ)
Hot-swappable on live AC800M rack?
Yes, but kill controller power first if possible. DIN-rail pull with load risks data glitch mid-backup. I’ve swapped live once—lost a recipe batch. Power down for safety.
New or refurbished condition?
New Surplus, QC’d on AC800M test rack. Inbound serial check, 24 V charge cycle with 0.05 A load burn-in using Fluke 115 voltage monitor. Full reports and charge logs on request. Cuts ABB direct pricing.
Lead time and warranty?
Stock ready, ships 1-2 days DHL. 1-year on capacity failure. Limited shelf life—Li-ion degrades after 5 years uncharged.
Config retention on swap?
Plugs into controller slot—no firmware flash needed. Match polarity on TK821V020 cable exactly or it won’t charge. Photo old setup first.
Replaces older AC800M batteries?
Direct fit for PM8xx controllers. Confirm 3BSE018172R1 marking; earlier revisions had shorter runtime.
Runtime under full load?
2-4 hours at 0.05 A max draw. Test your site’s memory use—large tag databases drain faster. Keep charged via 24 V continuous.
ESD handling protocol?
Grounded wrist strap always, ANSI/ESD S1.1. Li-ion terminals spark static easy. Dry panel shops have fried more than one for me—check continuity before grab.
