Cameron Sino PKT-03K replacement battery

Compatible two-way radio models

This Cameron Sino PKT-03K replacement battery fits the ProTalk LT radio and its matching battery cases PKT-03K, PKT-23, PKT-23K and SD2WL8019. It restores full operational runtime for professionals who rely on clear voice communication throughout a work shift. The secure-fit design matches the original mechanical profile so the radio sits correctly in chargers and belt clips. Installation is a simple swap that requires no tools or technical skill.

Capacity and headroom

High-quality cells deliver dependable power for continuous daily use without frequent recharging. The pack meets or exceeds the original manufacturer specifications so talk time and standby duration return to factory levels. Runtime will diminish naturally as the cells age through repeated charge cycles. Users needing multi-day operation without access to a charger should plan for a spare pack.

Practical limits of the radio interface

The battery connects through the radio’s proprietary contact layout, so it only works with the listed ProTalk LT and compatible case models. It cannot power devices that use a different pin arrangement or voltage requirement. Charging must be performed with the original desktop charger or an approved equivalent that matches the pack’s chemistry. Attempting to charge or operate the pack outside the specified radio family risks damage to both the battery and the equipment.
