Battery Impedance Testing

Regular impedance testing of batteries is an industry recommended and proven method of preventing critical battery failure. This is done by proactively identifying weaknesses and signs of deterioration in battery cells.

Battery Impedance Testing

Battery impedance is a measure of batteries’ internal resistance and is measured by applying DC to each battery, via probes attached to the block terminals. Lower internal resistance typically indicates higher capacity, as such an increase in the internal resistance of your batteries over time could highlight declining battery capacity.

By conducting periodical battery impedance tests (every 6 or 12 months, for example), compile a timeline of your systems battery performance. Testing makes it much easier to forecast the expected end-of-life date of your batteries accurately. Once you understand the batteries’ condition, your business can calculate when proactive replacements are required. Accurately allocating budget is then possible by predicting replacement ahead of time increasing, in turn, increasing reliability. Impedance testing does not affect live battery sets as the testing methods are non-intrusive and do not impact your business’s protection.

Battery Testing

Batteries are an essential component of any electrical device, hence the need for routine battery testing and maintenance at the cell level. The most frequent causes of unplanned outages include; battery blocks reaching a premature end of life. Issues are caused by batteries beginning to fail, leading an imbalance in the battery string that adversely affects the other batteries. Single bad cells could compromise your entire back up power system leaving you without protection. It is critical to have your batteries tested annually to run a smooth and successful power protection system.
