Battery Testing and Charging Device

Overview

This advanced battery testing and charging device is designed for users who require precise measurements of battery performance. It supports various battery types, ensuring compatibility with a wide range of applications. Ideal for hobbyists, technicians, or anyone needing reliable data on their batteries.

Key Features

• Power Supply Options: Operates on a DC5V external power supply or an 18650 rechargeable battery (not included).
• Battery Compatibility: Suitable for batteries with discharge voltages between 2.5V to 3.5V and charging up to 4.2V.
• Connection Interface: Utilizes a Type-C interface; users must provide their own power supply cable.
• Multilingual Support: Available in both Chinese and English languages.
• Testing Capabilities:

– Measures one-way charging and discharging (specific to compatible batteries).
– Internal resistance measurement using the DC two-wire method.

• Charging Functions:

– Supports one-way program-controlled charging at up to 1A (maximum).
– Hardware-controlled charging available at approximately 0.5A (maximum).

• Discharging Functions:

– One-way discharge support at about 1A (maximum), automatically halting when conditions are met.

• Automatic Operations:

– Fully automated charge/discharge cycle that stops when the set voltage threshold is reached (minimum stop voltage of 2.8V).

• Cyclic Testing Capability: Adjustable cycles from one to nine times.

• Status Indicators: Provides real-time status prompts during operation.

Technical Specifications

• Adjustable stop discharge voltages ranging from 2.5V to 3.5V across eleven levels.
• Fixed discharge current around 1A using two resistors; non-adjustable settings ensure consistent performance.
• Charging voltage regulated by a dedicated chip, achieving full charge at 4.2V with maximum currents of either 0.5A or 1A depending on the mode selected.

Dimensions & Weight

• Product weight is approximately 80g, with dimensions measuring 110mm x 88mm x30mm.

Usage Instructions

To initiate testing, install the appropriate battery and wait briefly for data stabilization before reading internal resistance and voltage parameters displayed on-screen.

Capacity Measurement Note

For accurate capacity readings, complete discharges are necessary; this process may take time as it requires waiting until automatic discharge concludes fully.

This device employs the DC two-wire method for internal resistance assessment based on Ohm’s law ( R = V/I ). A constant current forces through the battery momentarily while measuring resultant voltage drop—ideal for comparative analysis among similar batteries under identical conditions.
