Which type of batteries are directed not to be used with the TKL?

Which type of batteries are directed not to be used with the TKL?

• A. AA
• B. AAA
• C. C
• D. D

Answer: (A)

The TKL requires a power source that can deliver sustained, high current with stable voltage for the radio’s operation. Smaller cells like AA have higher internal resistance and much lower capacity, so during transmitter peaks the voltage can sag, performance can drop, and the power regulation in the TKL can be stressed. The TKL’s battery compartment and circuitry are designed around larger cells that meet the current and voltage needs, so using AA can lead to unreliable operation or damage. Larger cell sizes (the ones the TKL is designed to use) provide the necessary energy and proper fit, which is why AA-type batteries are specifically not directed for use with the TKL.
