Team Exalt Battery IR Checker, EXA9310

The Team Exalt EXA9310 Battery IR Checker is the ultimate tool for racers and hobbyists who demand consistent battery performance. Designed for accuracy, reliability, and ease of use, this device measures your battery’s true internal resistance (IR) and voltage level on the spot—allowing you to monitor pack health, match batteries, and maintain peak performance every race day.

Uses true 4-wire AC sine measurement technology, ensuring extremely accurate readings by eliminating errors caused by test leads or contact resistance. For the best consistency, always compare packs at the same temperature and nominal voltage.

Includes:
- USB charging cable
- High-quality 5mm bullet leads

Key Features
True 4-Wire AC Sine Measurement
Eliminates the influence of lead and contact resistance for unmatched accuracy—critical when evaluating high-performance LiPo packs.

Dual Interface & Battery Sorting Mode
Features two function screens, including an original battery-sorting mode for comparing packs quickly and efficiently.

Wide Measurement Range
Accurately tests from 0.00001Ω up to 200Ω, suitable for nearly every battery chemistry used in RC racing and electronics.

ZR (Zero-Range) Function
Activates ultra-low-resistance mode for measuring extremely low IR values down to 0.30–0.50 mΩ, perfect for competitive LiPo evaluation.

Built-In Rechargeable Battery
Powered by an internal lithium battery with low-power operation and multiple power-saving modes. Charges using any standard USB (Android-style) charger.

Supports Multiple Battery Types
Capable of measuring:
- LiPo
- LiHV
- Li-ion
- LiFePO4
- Lead-acid
- NiMH
- NiCd
- Alkaline & dry-cell batteries

Important Notes
- Do not input AC signals or any voltage above 100V DC into the device.
- Read all instructions and safety information before use.
- For the most consistent results, compare batteries at the same temperature and similar state of charge.
