Core Features
1. Tailored for Power System Decoders & Handheld Testers
The 3.7V 780mAh Power System Decoder Battery is purpose-built to match the power demands of power system decoders, handheld testers, and portable diagnostic tools. Its 3.7V nominal voltage and 780mAh capacity provide sufficient runtime for continuous testing tasks, while the low internal resistance (≤200mΩ) ensures stable power delivery for accurate measurements.
2. Extreme Temperature Resilience
Engineered to discharge in -25°C to 60°C, this battery operates reliably in frigid outdoor electrical grid inspections (-25°C) or hot industrial maintenance sites (60°C). Charging compatibility from 0~45°C also allows flexible recharging in workshops, field vehicles, or indoor labs.
3. Robust ABS+PC Casing & Gold-Plated Terminals
Housed in ABS+PC engineering plastic casing, the battery withstands physical impacts and environmental stress during field use. Gold-plated spring output terminals enhance electrical conductivity and reliability, reducing contact resistance for consistent power transfer to devices like power system decoders or handheld testers.
4. Precision Protection with Imported Chips
Equipped with imported Seiko protection chips, this battery offers high-stability monitoring and precise control for short-circuit, overcharge, over-discharge, and overcurrent protection—minimizing safety risks and extending cycle life in demanding testing scenarios.
Application Scenarios
The 3.7V 780mAh Power System Decoder Battery powers:
- Power System Decoders: Devices used for electrical grid decoding, signal analysis, or infrastructure diagnostics in utility and industrial settings.
- Handheld Testers: Multimeters, cable testers, or sensor calibrators used in field maintenance, electronics repair, or engineering inspections.
- Portable Handheld Devices: Diagnostic tools, data loggers, or compact measurement instruments in industrial, automotive, or telecommunications fields.
