1. Accurate Core Battery Health Detection
This tester precisely measures battery voltage, internal resistance and cranking status. It accurately judges aging, capacity decay and faulty cells for automotive and UPS batteries.
2. Dual Scenario Compatibility
It fits 12V vehicle starting batteries and standby UPS battery packs. One device covers daily inspection of auto power systems and industrial backup power equipment.
3. Fast Risk Diagnosis Prevents System Failure
It quickly identifies poor cranking performance, low voltage and abnormal discharge. Early detection avoids vehicle startup failure and UPS power outage risks.
1. High-Precision Battery Internal Resistance (Core Health Judging Parameter)
Peakmeter battery testers support ultra-wide internal resistance measurement range from 0.001mΩ to 3000mΩ with basic accuracy up to ±(0.5% reading + 2 digits), adopting 1kHz low-disturbance AC test signal to eliminate DC polarization error of lead-acid, lithium and NiMH batteries. It precisely captures tiny resistance changes caused by aging plates, electrolyte drying, loose lugs and shorted battery cells; low internal resistance indicates intact, high-output batteries, while sharply rising resistance signals capacity attenuation and hidden overheating risks. The four-terminal Kelvin probe design completely filters test clip and wire contact resistance interference, ensuring stable micro-ohm level readings for single 18650 lithium cells and large series-connected UPS battery packs.
2. Multi-Range DC Open & Load Voltage with Tiered Calibration Accuracy
The instrument accurately measures DC voltage covering 0.001V–100V, with measurement accuracy controlled within ±0.2% full scale, supporting both open-circuit static voltage and simulated load terminal voltage testing for comprehensive battery state judgment. It identifies undercharged, fully charged, over-discharged and failed short-circuited cells by matching voltage thresholds of 1.5V dry batteries, 12V car lead-acid batteries, 3.7V lithium cells and 48V solar storage packs. Unlike ordinary multimeters only measuring static voltage, Peakmeter simulates actual discharge load to detect severe voltage drop that exposes batteries with sufficient static voltage yet poor discharge capacity, greatly improving fault screening accuracy for vehicle maintenance and energy storage inspection.
3. Real-Time Battery Surface Temperature & Temperature Compensation Correction Data
Equipped with integrated thermistor probe and built-in infrared temperature detection module, Peakmeter testers accurately measure battery surface temperature from -20℃ to 120℃ with ±0.8℃ precision, automatically linking temperature data to resistance and voltage readings for algorithm compensation. High temperature accelerates battery aging and distorts internal resistance test results; the tester records temperature synchronously with electrical parameters to avoid misjudging normal high-temperature resistance drift as battery failure. This parameter is critical for long-running UPS battery rooms, electric vehicle power packs and outdoor solar batteries, helping technicians spot abnormal heat accumulation that may trigger swelling or fire risks in advance.
