Import Battery Discharger & Capacity Tester — Buy in Bulk from Supplier in China

The Foresight Electronics 840CT battery discharger and capacity tester covers a 10-300 V voltage range with maximum discharge current of 120 A on 12-120 V systems and 60 A on 220-280 V systems. It employs a 5.7 inch LCD touch screen for real-time parameter display and direct menu operation. The unit supports three selectable discharge modes: constant current (0-120 A), constant power (0-14 kW), and constant resistance (0.16 ohm minimum). Four adjustable stop points control discharge termination: group low voltage (0-250.0 V), discharge time (0-99 hours 59 minutes), discharge capacity (0-9999 Ah), and cell low voltage (0-15.00 V). Wireless modules monitor 1.2 V, 2 V, 6 V, and 12 V cell voltages in real time, with each module handling four batteries simultaneously rather than the single-battery limit of traditional cable methods.

The 840CT uses non-volatile 8 Mbit Flash internal memory to store multiple independent discharge records without a laptop, with data retrievable via USB or RS232. PC analysis software generates voltage curves, resistance bar charts, capacity histograms, and automatic Excel reports. Optional clamp current extends external current measurement to 0-600 A. The instrument carries CE certification to LVD 2006/95/EC (EN 61010-1) and EMC 2004/108/EC standards. Operating conditions span -5 to 50 degrees C with 5-95% RH humidity tolerance, and altitude limit of 4000 m. Power input is 220 V AC at 50/60 Hz with 350 W maximum consumption. Internal current measurement accuracy is 0.5% with 0.1 A resolution; voltage measurement accuracy is 0.5% with 0.1 V resolution on group voltage and 0.01 V on individual cells.

This tester serves power supply departments in utilities, telecom operators, data centres, and industrial facilities maintaining DC battery banks at 24 V, 48 V, 110 V, 120 V, 220 V, and 240 V. Typical buyers include maintenance engineers and procurement managers seeking unattended automatic discharge testing for lead-acid and nickel-cadmium battery groups. The 840CT replaces manual discharge methods with programmable profiles that simulate actual load conditions for accurate capacity evaluation. Buyers should confirm with Foresight Electronics whether wireless modules, current clamps, and PC software licences are included or priced separately, and verify calibration certificate availability for their local standards.

Foresight Electronics Co., Ltd. is located at Xi'an Foreign Building No.68, middle sector Huancheng Road, Xi'an 710054, Shaanxi Province, China. The supplier holds an imported tier designation and a harbor trust tier on the platform. The response rate is recorded at 0.00% with zero average response hours, which indicates no response data is available rather than active communication. The listing presents the 840CT battery discharge tester as its primary product, with detailed technical documentation including CE certification, multi-language capability through the touch interface, and PC software for report generation.

The company profile does not state founding year, registered capital, factory size, headcount, annual revenue, or named clients. No information is provided about ISO quality management certification, R and D team size, or after-sales service infrastructure. Buyers should verify directly with Foresight Electronics whether the supplier manufactures the 840CT in-house or sources it under OEM arrangement, and request factory audit or third-party verification documents before committing to volume orders. The Shaanxi location places the supplier in an established electronics manufacturing region with access to Xi'an's aerospace and power electronics supply chain.
