which GMRS (two way radio) has the highest talk time?

Question

i work in a press. it is loud and communication is crucial.

im looking the longest talk time and i also would like to know if it will work in a lot of noise in the background.

...and what are the construction workers using?

Answer 1

GMRS radios list their transmit range under ideal conditions. The fine print typically states the battery life under assumptions such as 5% talk time. Talk time is all about the batteries you're using.

For maximum battery life, use batteries with the longest milli-Ampere-hour (mA-h) rating and talk (transmit) as little as possible.
