FAQ

1. What is the ABB 3BSC760019E1 battery?
The ABB 3BSC760019E1 is a rechargeable lithium-ion battery identified with the ABB SB822 designation. It is designed for use in compatible ABB industrial control system equipment where a compact rechargeable power source is required for backup or data-retention functions. The battery has a nominal voltage of 3.7 V and a capacity of 2.4 Ah, making it suitable for dedicated low-power backup applications within the control system.

2. What is the 3BSC760019E1 battery used for?
The 3BSC760019E1 is primarily used as a rechargeable backup battery in compatible ABB control system equipment. Depending on the specific system configuration, the battery can provide power for functions that need to retain information or maintain a required operating state when the primary system power is unavailable. When selecting a replacement, the complete ordering number should be verified rather than choosing a battery based only on its physical appearance or electrical characteristics.

3. What are the voltage and capacity specifications of the 3BSC760019E1?
The 3BSC760019E1 has a nominal voltage of 3.7 V and a rated capacity of 2.4 Ah. The capacity represents the approximate amount of electrical charge available under specified conditions. Actual available capacity can vary depending on operating temperature, charging condition, battery age, discharge rate, and storage history. These factors should be considered when evaluating backup performance in an installed control system.

4. Is the ABB 3BSC760019E1 rechargeable?
Yes. The 3BSC760019E1 uses rechargeable lithium-ion technology and is intended to operate with the charging and battery-management system of compatible ABB equipment. When installed in the correct system, the battery can be recharged during normal operation. For stored spare batteries, periodic maintenance is recommended so that the battery does not remain at an excessively low state of charge for an extended period.

5. How should the 3BSC760019E1 lithium-ion battery be stored?
For long-term storage, the battery should be kept in a suitable, dry environment away from direct sunlight, excessive heat, moisture, and other adverse conditions. A recommended storage temperature range is approximately -20°C to +25°C. For extended storage, the battery should be checked periodically and recharged approximately once a year to around 40% capacity. The battery should also be protected from excessive discharge, with the cell voltage maintained above the recommended minimum level.

6. What precautions should be taken when replacing the 3BSC760019E1?
Before replacing the battery, place the associated control equipment in the appropriate maintenance condition and follow the equipment-specific safety and shutdown procedure. During removal, avoid pulling directly on the battery wires or connector, as this can damage the connection or circuit board. When installing the replacement battery, verify the part number, connector, polarity, and installation position. After installation, check that the connector is fully seated and confirm that the control system reports the expected battery status.

7. What should be checked if the 3BSC760019E1 provides significantly less backup time?
Begin by checking the battery age, charging status, and operating history. Lithium-ion batteries gradually lose capacity as they age and undergo repeated charge and discharge cycles. The charging circuit and battery connector should also be inspected for abnormal conditions, loose connections, or poor contact. If the battery reaches its expected charging condition but backup time has become significantly shorter, its remaining capacity may have degraded. In that situation, replacement with the correct battery specification is generally required rather than continuing to rely on a severely degraded battery.

8. Why should the 3BSC760019E1 be periodically maintained during long-term storage?
A lithium-ion battery can gradually lose charge even when it is not connected to equipment. If it remains at a very low state of charge for a prolonged period, its voltage can fall below the recommended operating range and its ability to accept or retain charge may be affected. Periodic inspection and appropriate charging help maintain the battery in a suitable storage condition. Storage temperature is also important because prolonged exposure to high temperatures can accelerate battery aging and reduce its long-term service performance.
