UPS MAINTENANCE – UPS BATTERY SERVICE
When maintaining UPS batteries, new installations do not require initial checks as they are pre-charged. It is crucial to ensure that the UPS is actively charging its batteries. Most modern UPS units perform self-tests weekly or monthly, indicating any issues on the display. Key issues to look for include low voltage, failed batteries or cells, and failed fuses. Regular visual inspections are recommended to check for leaks, damage, or unusual smells which may indicate leaks or connection issues, and maintenance should always be performed by a trained engineer. Batteries should be replaced every four years or by year eight for batteries designed for ten years. For assistance with new UPS batteries, contact Power Continuity.
It is not necessary to check UPS batteries that are NEWLY installed, as they are pre-charged.
However, it is essential that the UPS is charging its batteries. UPS continually drip feed the batteries to keep them fully charged at all times.
Most Modern UPS carry out a ‘self test’ every week or month so the result will only be shown on the display if the self test has flagged up any issues.
Issues such as – Low Voltage – A failed Battery- A failed cell in a battery- failed fuse.
How to Check UPS Batteries
A regular visual check is useful as part of your UPS service and Maintenance regime
- Leaks or powder forming around terminal or base of batteries.
- Check that any battery has not been damaged or knocked during inspections.
- Any visible leak
- ‘Eggy’ smell which indicates a leak is happening which you can’y yet see
- ‘Burning’ type smell which indicates that a battery terminal may be loose or cable connection requiring attention
Any and all maintenance should be undertaken by a trained engineer. Always check the UPS batteries. Never allow battery terminals to be covered with powder as this photo. This occurs with age and lack of battery replacement Replace UPS batteries at least every 4 years or in the case of 10 year design life batteries , we suggest replace in year 8 no later. Failure does and can happen. Better to replace rather than fail.
