Battery life & efficiency

[born2hunt]

Is a unit less efficient when battery life has dropped off to half or lower, or does it operate the same throughout?

Thanks in advance,

This is by no means a scientific study. I have not noticed any drop off in performace down to about 2-3 out of 5 total bars on my 2500. The worst hunt (and only skunk) of my career came on a hunt with my large imaging coil installed and the battery meter steady on 2 bars. Nothng worked properly. I got falses all the time no matter how low I set sensitivity. I couldn't pinpoint. I thought the coil was bad. I checked and rechecked all the connections. I rebooted. No joy. I had to go home to get my stock coil and returned to find a few coins even with the old batteries. I then installed new batteries and all was well with both coils.

I now use rechargeables, good ones, and recharge after 15-20 hours of hunting when the battery meter fluctuates between 3-4 bars. You can get a dual use charger and batteries for about 30 bucks. If you need 8 batteries add another 12 bucks. Best advice I ever got on this forum except for Kenny's and John's pinpointing hints.

on the ace 250 it has 4 bars, I replace when it gets to one bar, performance does not drop at all that I have noticed

Operates the same. I usually replace when it gets down to one bar.
