Volume difference between disposable and rechargeable batteries

Post by Dutchie on Mon Nov 17, 2014 6:22 am

For your information - A couple of weeks ago my standard rechargeable batteries ran out and I changed them for Duracell disposables. I was very happy with the volume controls on my headphones, because the first beep seemed to pierce my eardrums. The output volume with the disposables was a _lot_ higher than normal. I wasn't sure if the higher volume also meant that the detector would operate more efficiently, or, if I had been searching with a less than optimal setup with rechargeables. I mailed Cscope about this, and I was reassured by their answer:

--- Cscope answer, October 14, 2014 ---
Good Morning, thanks for your message. You are correct, the audio section section is powered directly from the batteries so the sound will be a bit lower when re-chargeable batteries are used as their operating voltage is 1.2 Volts whilst a non rechargeable batteries voltage is 1.5 Volts. However the circuitry that does the actual detecting uses a lower "regulated down" voltage so that even if the battery voltage drops, the transmit and receive section still operates at maximum sensitivity. Hope that helps
