YR1035 YR1030 Battery Internal Resistance Tester 4 Wire

The YR1030 and YR1035 Battery Internal Resistance Testers are purpose-built tools for technicians, engineers, and electronics enthusiasts who demand accuracy and reliability. They use true four-wire AC sine measurements to eliminate lead resistance and contact errors, delivering precise readings of both battery voltage and internal resistance. Ideal for battery matching, performance testing, and screening, these compact testers make it easy to identify weak cells, sort batteries, and assess overall battery health in the field or workshop.

Both models share powerful features: a true four-wire measurement method, dual-function interfaces including a convenient battery sorting option, a HOLD function to lock readings, and an energy-saving design. The YR1030 adds a robust test range, automatic range switching for quick, stable readings, and a bright dot-matrix LCD that clearly displays voltage, resistance, and battery classification. The YR1035 emphasizes portability and practical field use with a built-in charging capability and a compact form factor, while maintaining the same accurate four-wire testing core.

Benefits & Tips

• Accurate screening: measure voltage and internal resistance simultaneously to quickly identify healthy versus degraded cells.
• Low-resistance testing: ZR function enables measurement of very low internal resistance (down to about 0.30–0.50 milliohms) for high‑drain batteries.
• Easy readings on the go: HOLD locks the display for easy note‑taking, and automatic range switching provides fast, stable results in real time.

Warnings & Reminders

• Operate within the specified voltage measuring range (0–28V) to prevent damage or inaccurate readings.
• Ensure correct connection to the battery under test to avoid short circuits or misreads.
• Use the auto-range or manual range as described for stable results; avoid forcing measurements beyond the device’s limits.
• Keep away from moisture, dust, and extreme temperatures to preserve accuracy and longevity.
• If using the charging function, select the appropriate current (200mA or 400mA) and monitor the unit during charging.
