How often
How often should a battery impedance / capacity tester be calibrated?
Battery testers should be calibrated every 12 months, or before any critical UPS or standby power audit.
Accredited ranges
Battery Impedance / Capacity Tester calibration ranges & measurement uncertainty
The parameters, ranges and calibration & measurement capability (CMC) below are taken from our SAC-SINGLAS Schedule of Accreditation (LA-2023-0845-C, to ISO/IEC 17025). CMC is the smallest measurement uncertainty we can achieve under accredited conditions.

Questions
Battery Impedance / Capacity Tester calibration FAQ
How often should a battery impedance / capacity tester be calibrated?
Battery testers should be calibrated every 12 months, or before any critical UPS or standby power audit.
Is battery impedance / capacity tester calibration accredited?
Yes. Battery Impedance / Capacity Tester calibration is covered under our SAC-SINGLAS scope of accreditation (LA-2023-0845-C, ISO/IEC 17025), covering DC voltage 0 mV to 1020 V and resistance 0 Ω to 1200 MΩ. Certificates state the measured values and measurement uncertainty, traceable to national and international standards. Where an instrument falls outside the accredited ranges, we can calibrate it as a traceable service instead.
How long does battery impedance / capacity tester calibration take?
Standard turnaround is 5 to 7 working days; express service is 2 to 3 working days. Collection and delivery in Singapore are free for orders above $300.
Which brands of battery impedance / capacity tester do you calibrate?
Commonly submitted brands include Fluke and Hioki. This list covers the models customers most often send in, not our full capability — send us your make and model and we'll confirm whether it falls within our accredited scope or can be calibrated as a traceable service.
