BATTERY TESTER

The Battery Tester category features a range of digital and analog testers designed to measure the voltage, capacity, charge level, and internal resistance of various battery types. Whether you're working with Li-ion, LiPo, NiMH, NiCd, lead-acid, or alkaline cells, these testers are essential tools for battery diagnostics and maintenance.

Battery testers help determine:

• State of charge (SoC)

• Battery health (internal resistance, wear level)

• Remaining capacity (in mAh or %)

• Load performance under real usage conditions

Types of testers include:

• Handheld multimeter-style battery testers

• Load testers with LED or LCD display

• USB inline battery analyzers

• Smart testers with PC interface for graphing charge/discharge curves

Key features:

• Supports 1.2V to 24V battery types

• Real-time voltage and capacity readouts

• Detection of dead cells, weak batteries, and charge retention

• Support for AA, AAA, 18650, CR2032, 9V, and more

• Models with multi-slot testing for multiple batteries simultaneously

• Some include USB power bank testing and charging current display

Applications include:

• Battery maintenance in electronics and RC hobby

• Battery pack assembly and balancing

• Power bank evaluation and testing

• Educational labs and R&D diagnostics

With accurate readouts and portable designs, these testers are a must-have for anyone working with battery-powered devices, drones, robotics, or solar-powered electronics.
