Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • CMOS Backup Power: Provides reliable 3.0V lithium power for Real-Time Clock (RTC) and CMOS memory in laptops, home appliances, and electronic devices.
  • Easy Integration: Pre-installed cable connectors (e.g., JST-style) ensure seamless replacement and secure wiring, minimizing electromagnetic interference (EMI) through twisted wires.

Key features

  • 1. Advanced Material Technology

    • With a corrosion-resistant lithium core and twisted-wire design, reduce electromagnetic interference (EMI) by up to 30% compared to non-twisted models*. This ensures stable power delivery in sensitive electronic devices like laptops and home appliances.

  • 2. Universal Interactive Design

    • With a pre-attached cable connector and compact coin-shaped form, easily integrate into laptops and home appliances without custom wiring. Installation is up to 20% faster than models requiring manual connections*.

  • 3. Optimized Performance Parameters

    • With a 3.0V nominal voltage and high energy density, provide reliable power for extended periods. Lasts 25% longer than standard CR2032 batteries*, ensuring uninterrupted operation for devices like laptop RTC backups and smart home systems.

  • 4. Versatile Scenario Solutions

    • With a compact design and durable construction, this battery is ideal for both home appliances (e.g., memory backup in thermostats) and commercial electronics (e.g., continuous operation in POS systems). Its yellow color-coding simplifies quick identification in multi-battery setups.

  • 5. Safety-Certified Compliance

    • With compliance to international safety standards (e.g., UL and RoHS), ensure safe operation in sensitive environments. Built-in safeguards prevent overcharging/over-discharging, reducing risks common in lithium-ion batteries.
