Description
Megger BITE3 Battery Impedance Tester Repair
The BITE3 doesn’t load-test a battery to failure — it measures internal cell impedance, a non-invasive indicator of battery health that flags weak cells before they fail. That makes it a precision low-level measurement instrument, and its faults are measurement-accuracy and connection faults rather than high-power failures.
June Company repairs and calibrates the BITE3 for battery-maintenance crews tracking stationary-cell health over time.
Common BITE3 problems we fix
- Impedance readings drift or look wrong — measurement-circuit drift; since impedance trends decide which cells get replaced, accuracy is everything. Recalibrated against standards.
- Won’t take a reading / no connection — test-lead and front-end faults that stop the impedance measurement, repaired.
- Inconsistent readings between cells — front-end or contact issues, corrected for repeatable results.
- Won’t store or transfer data — memory/interface faults affecting trend logging.
- Display or battery faults on the handheld.
FAQs
My impedance numbers don’t match my history — fixable? Yes. Drift in the measurement circuit throws off trend comparisons; we recalibrate so new readings line up with your baseline and weak cells show up correctly.
Is it certified after repair? Yes — measurement accuracy verified against our reference standards with a NIST-traceable certificate.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.
