Key item features

  • Enhanced Capacity: Kastar high-capacity batteries deliver ultra-strong power, ensuring devices perform well and operate for extended durations.
  • Precise Specifications: Each Ni-MH battery features 2.4V voltage, 500mAh capacity, and measures 44.5 x 20.5 x 10.5mm.
  • Extended Lifespan: A mix-protection additive in the cathode prevents material degradation during charging and discharging, extending the battery's lifespan up to 1200 cycles.
