Special Features

  • [True High Capacity & Long-Lasting] Real 500mAh (4500mWh) – far more than NiMH (200mAh) or alkaline 9V. Powers devices longer between charges, and with 1000 recharge cycles, it's both eco-friendly and cost-effective.
  • [Built-in USB-C with 3-Hour Fast Charging] Integrated USB-C port – no extra charger or dock needed. Comes with a 4-in-1 USB-A to USB-C cable. Fully recharges in just 3 hours, much faster than NiMH batteries. LED indicator shows charging status.Built-in multiple protections (overcharge, over-temperature, overload, short-circuit) for safe use.
  • [Smart Low-Battery Alert for Smoke Alarms] When battery runs low (<10%), voltage automatically drops from 9V to 3V, reliably triggering the low-battery chirp on smoke detectors, fire alarms, and CO alarms – so you never miss a replacement reminder.
  • [Noise-Free for Musical Instruments] Optimized internal circuit eliminates buzzing or humming noise found in older rechargeable 9V lithium batteries. Perfect for guitar effects pedals, wireless microphones, and other audio equipment where clean sound matters.
  • [Wide Compatibility for Countless 9V Devices] Ideal for smoke detectors, fire alarms, CO detectors, security sensors, guitar pedals, wireless mics, multimeters, walkie-talkies, remote controls, clocks, toys, cameras, flashlights, medical devices (e.g., patient monitors), GPS units, portable radios, electronic games, and more. One battery powers everything.
  • [What You Get] 4 × HW 9V Rechargeable Lithium Batteries (500mAh / 4500mWh), 1 × 4-in-1 USB-A to USB-C Charging Cable, 12-Month Product Care Service.
