Battery Burn

A

Anonymous

Guest
While looking to purchase a P.I. detector I noticed a great difference in battery burn time. One model uses two 9 volt batteries in 6-9 hours, another uses 8-AA batteries in 25 hours and the 3rd used 8-AA batteries in 100 hours. Is it because the performance is better on a high battery usage detector? Thanks for the help. HH
 
Ron,
All I know is that there is no correlation between a "high performance PI detector" and battery drain.
I think battery drain is more likely linked to the circuitry's general efficiency, and in conjunction with a higher pulse rate (or pulses per second), pulse width, etc. Because PI's also have a "duty cycle", that is, they are basically turning on and off, battery usage is typically very good.
That's about all I know, so I'll say no more.
Hope the info helps.....I'm sure others will provide more details to your question.
Tony.
