Import Battery Internal Resistance Tester — Buy in wholesale FOB from Supplier in China

The Battery Internal Resistance Tester from Wuhan GDMK Electric Co., Ltd. is a portable diagnostic instrument designed for measuring voltage and internal resistance across single or grouped cells using AC discharge methodology. The unit supports both key-operated and liquid crystal touch screen interfaces, enabling operators to switch between single battery measurement, group battery measurement, and oscilloscope display modes. It is intended for capacity estimation, pre- and post-discharge internal resistance comparison, and matching of new battery internal resistance in maintenance or assembly environments. The compact, lightweight housing is built for field portability and workshop use.

The tester operates on AC discharge test principles, a standard approach for non-invasive assessment of lead-acid, lithium-ion, and nickel-based battery chemistries. Typical measurement ranges for comparable instruments span 0.0001 mOhm to 300 Ohm for resistance and 0 V to 60 V for voltage, though buyers should confirm exact ranges with the supplier. The oscilloscope function allows visual waveform analysis of battery response under test, useful for detecting intermittent faults or cell degradation patterns not apparent from numeric readings alone. Dual operation modes (physical keys and touch screen) accommodate both gloved workshop use and rapid data entry in controlled environments.

This instrument serves battery manufacturers, renewable energy installers, data centre maintenance teams, and electric vehicle service workshops requiring traceable cell condition data. Applications include incoming quality control for battery banks, preventive maintenance scheduling for UPS systems, and warranty validation for traction battery packs. Importers should clarify calibration certificate inclusion, probe accessory compatibility, and whether firmware supports multiple languages. The supplier's location in Wuhan's Jiangxia District Economic Development Zone offers access to central China logistics hubs, though sea freight to most overseas markets will depart from Shanghai or Shenzhen ports.

Wuhan GDMK Electric Co., Ltd. is headquartered in the Jiangxia District Economic Development Zone of Wuhan, Hubei Province, with its registered address on Huangjiahu Avenue in the Daqiao New District. The supplier holds a harbor trust tier classification within the marketplace verification system. The company operates from a central China location with access to Wuhan's established electronics manufacturing ecosystem and rail-connected logistics infrastructure. No response rate or average response time data is available from the current profile, which indicates buyers should anticipate potential delays in initial enquiry turnaround.

The supplier's listed product focus centres on battery testing instrumentation, specifically internal resistance measurement equipment for industrial and commercial battery maintenance. The source description emphasises AC discharge technology, dual interface operation, and both single-cell and multi-cell measurement capability. No information is provided regarding ISO certification, factory audit status, export licence details, or specific clientele sectors. Buyers should independently verify manufacturing capability, quality management system registration, and whether the company produces the instrument directly or sources from an OEM partner.
