You guys mentioned keep battery 1/3 to 2/3 charged...Not very good at tech stuff, but How do I do that...When I'm done hunting for maybe 4 or 5 days, I just put the charger on my Nox 600 and the wireless headphones and let them go til the lights tell me they are done....Tell me what you mean....Pete
There's no easy, yet precise way to do it. What I'd do is charge it 100%, then use it until the moment I see it going from 2 bars to 1. Presumably, this gets you to about 1/3 charge.
Alternatively, you could use it until the moment it goes from 3 bars down to 2.
I'd use the first method if I was pulling a lot of juice from the Equinox. We're talking wireless on, backlight on, volume on the highest setting and actively hunting with it.
If just letting is sit idle, with onle the LCD segments "on," I'd use the second method. The current draw will be lower, which means an ever so slight reduction in the voltage sag of the battery. This means the battery bar indictor will trip later, than if drawing more current from the cell.
These battery meters don't detect the actual state of charge of the battery (as that's practically impossible). Instead, they only measure the voltage of the cell, then the software extrapolates this reading (maybe even comparing it to the current being drawn from the cell at the time of measurement) to estimate a current state of charge of the battery.
All that being said, you could just refer to the amount of hunting time you get from a fully charged battery. On your next hunt, start off with a battery at 100%. Then you just stop hunting when you get to that halfway point.
