Frequently Asked Questions

How long does the BK Technologies BKR0101 battery last on a single charge?

Runtime varies based on usage, but with its 4900mAh capacity, many users experience approximately 18–24 hours under a standard 5-5-90 duty cycle. Higher power settings, frequent transmissions, or continuous GPS use may reduce overall runtime.

Is the BKR0101 compatible with my current charger or older BK radios?

No. The BKR0101 is specifically engineered for the BKR5000 series radios and requires BKR5000-compatible smart charging hardware. It is not compatible with legacy KNG series radios, chargers, or older battery architectures.

Why should I use a “smart” battery like the BKR0101?

The SURPASS smart technology built into the BKR0101 stores and communicates key battery data—such as health, cycle count, and remaining capacity—to your radio and compatible smart chargers. This helps you monitor power more accurately and can support longer battery life by enabling chargers to apply the correct maintenance profiles only when needed.

What safety and usage guidelines should I follow?

To protect performance and safety, avoid exposing or storing the battery in temperatures above +60°C (+140°F), such as inside a vehicle parked in direct sunlight. Do not attempt to modify the battery pack or solder directly to the external terminals, and always use approved BK Technologies charging accessories (such as the BKR0303 single-unit desktop charger or the BKR0300 six-bay multi-unit charger) for safe, proper charging.
