batteries and performance

[jeeper]

I have always wondered about this with any electronics. Do you feel your detector performs at the same level throughout the battery life, or do you switch them out befor they reach, say, 25 or 50 percent of their charge. I could switch them out at half, then put the used ones in my kids toys. Just wondering if anyone else wastes their time thinking about this. Thanks guys.

I believe there's something in the circuitry that maintains the necessary level of power until they are too far gone. I run them until the detector says change them and have never felt the level of performance has dropped off.

I'm ultra-paranoid and change my F75 batteries if they drop below full strength on the readout. I also use rechargeables. But jimmyk is probably right and you can keep going with them until the machine says "enough".

I run mine till 1 bar on the meter on my F4 and it still seems to work as usual.

Voltage regulator circuitry will regulate the required voltage necessary for your machine to operate to spec. It's not like if you put in fresh batteries (at say 6V total) , that when the battery meter drops down a segment now your running at say 4V, so you get 33% less depth. The machine is probably set up to operate at 5V (very common for digital microelectronic circuitry), and once the batteries go below 5V threshold the battery segment on the display will indicate it's time to replace them.

I have to admit, I have about 50 hours on my F70, and I'm still on the first set of batteries. Unbelievable, as the older Fishers that run on two 9V batteries don't last half as long as four AA's, yet they have three times as much energy to play with.

I always use top of the line AA 9 volts in my detector and uniprobe. And I never let it go down to the last bar. I have found name brand is the way to go and I never use rechargeable never
