Buyers needing a different voltage, chemistry or connector layout should look elsewhere.

Low-Heat Operation

Ni-MH chemistry runs cool during typical charge and discharge cycles, so the pack adds negligible thermal load inside the handset enclosure. No active cooling or ventilation changes are required when swapping the original cell. Overcharge, over-discharge, over-voltage and short-circuit protection circuits limit stress on the cells during normal use. The 4.32Wh energy rating supports extended talk time without excessive temperature rise.

Certified Safety

The pack carries ISO9001, RoHS, CE, UN38.3 and MSDS certifications, confirming compliance with quality management, substance restrictions and transport safety standards. These marks mean the battery has passed mandatory electrical and environmental tests before shipment. No additional software, firmware updates or configuration tools are bundled or required for installation. The protection circuitry is self-contained and transparent to the host device.
