| The 9Z has some voltage drop between the battery and the alarm circuit, so 8.5 V in the 9Z is the same as 8.8 V in something like the 8U. You'll also that the voltage fresh off the charger is a bit lower than you'd see in other radios.
Like David, I have never seen a 9Z go dead so soon after the alarm starts up. With the old 800 mAh pack, I had mine go for at least five minutes, possibly up to ten minutes with the beeper going. I was doing a setup and didn't want to take time out to recharge. In the end the beeping wore me out, but the radio was still going. |
