Emergency power systems rely on batteries to deliver power at the right moment to start a generator or to run a UPS. Neglected batteries, however, are the most common reason for backup power failure, which is why facility managers use automated battery testing systems to assess battery health.
Issues that can affect battery performance include:
- Batteries don’t display outward indications of impending failure.
- Replacing batteries before end of life can invite new risks of manufacturing errors.
- Depending on usage, a battery may fall short of lifespan expectations.
- High temperatures within battery cells can accelerate corrosion.
- Undercharging can lead to capacity loss; overcharging can cause cells to dry out.
Analysis of battery health should be an expected part of any effective healthcare or critical power facility design and energy management plan for uninterrupted power – and peace of mind.
