Applications

Where the Molicel M35A Protected Battery Excels

Thanks to its built-in protection circuit, high capacity (3500mAh), and 10A continuous discharge rating, the Molicel M35A is best suited for moderate-drain applications that prioritise safety, runtime, and stability:

  • High-performance flashlights and LED torches
    Ideal for users who need extended runtimes without the risk of over-discharge or overheating — great for outdoor, tactical, or professional lighting gear.

  • Portable medical equipment
    Reliable power source for moderate-drain healthcare devices that require consistent, protected output — such as diagnostic tools or monitoring units.

  • Emergency power banks and backup systems
    Perfect for devices where stable output and safety are essential, especially in off-grid or critical-use scenarios.

  • Custom-built battery packs
    Used in DIY or commercial packs where added protection is required — especially in projects that prioritise safety over raw discharge performance.

  • Consumer electronics and wireless devices
    Suitable for laptops, handheld tools, and gadgets that operate within moderate power ranges, offering longevity and protection from short circuits.

Important Information

While the Molicel M35A includes integrated protection circuitry, all lithium-ion batteries must be handled with care. Improper use can lead to fire, explosion, serious injury, or property damage.

Please read and follow these safety guidelines before purchase or use:

General Lithium-Ion Battery Safety

  • Only purchase if you understand Li-ion battery safety and proper handling procedures.

  • Always use a compatible Li-ion smart charger. Never leave batteries charging unattended.

  • Store batteries in a protective case — never carry them loose in your pocket, bag, or toolkit.

  • Avoid contact with metal objects such as keys, coins, or tools to prevent accidental short-circuiting.

  • Use within manufacturer-rated specifications. Do not exceed voltage, current, or temperature limits.

  • In series or parallel packs: ensure proper cell balancing and use a quality Battery Management System (BMS).
