UPS Batteries – How to Check

UPS Batteries – there is no need to check UPS batteries that are NEWLY installed as they are pre-charged, without the need to check them again.

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 and 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.

A regular visual check is useful as part of your UPS service and Maintenance regime

  • Check for leaks or powder forming around terminal or base of batteries.
  • Check that any battery has not been damaged or knocked during inspections.
  • Check for any visible leak
  • Check for any ‘eggy’ smell which indicates a leak is happening which you can’y yet see
  • Check for any ‘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.

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.
