Accurate & repeatable results in seconds

Our multi-frequency battery analysers test the electrochemical properties of a battery using CELScan™ technology. This technology enables us to measure and report the Voltage & Impedance (electrical) properties as well as the Sulfation & Dryout (chemical) properties of lead acid batteries.

Measuring capacity loss due to Sulfation and Dryout presents us with leading indicators of a battery’s State of Health (SoH) and enables us to react early to those  batteries requiring intervention – saving time, money and risk. Lagging indicators (Voltage | Impedance) only identify failures after the fact when it is too late.

The technology works on a wide range of lead acid batteries (FLA, SLA, VRLA, Gel, AGM), is non-intrusive and can be performed on-float without any disruption to your power environment. The process takes mere seconds per battery – permitting fast, large scale testing.

Accurate knowledge of individual battery health empowers clients to reduce destructive and time consuming load testing practices.

We accurately identify:

  • Client backup power capacity – at individual battery level
  • Defective batteries
  • Defective peripheral assets
  • Environmental anomalies
  • Remedial actions for all reported concerns

We facilitate:

  • Understanding of your battery ecosystem capability and performance
  • Increased lifespan of batteries and battery banks
  • Time and money saving
  • Risk mitigation

Leading vs Lagging indicators

As indicators of a battery’s State of Health (SoH), Voltage and Impedance are inadequate as their values generally only deteriorate at the end of the battery’s life. This is why they are known as lagging indicators.

Voltage and Impedance measurements also give no indication of capacity loss due to sulfation or risk due to dryout, until it is too late.

The accuracy of ElectroChemical analysis technology

It is clear to see how electrochemical testing produces accurate results in a fraction of the time.

The capacity of 52 batteries was analysed using;

  1. ElectroChemical analyser – taking 20 minutes
  2. Client’s load test – taking 5 hours

The electrochemically analysed capacity per battery is indicated by the grey lines. The 5 hour load test end voltage analysed capacity per battery is indicated by the blue lines.
