Battery life
Batteries will last about 3-4 months if they are left in the QED, after which time the batteries may be fully discharged and you will need to throw them away.
 

If you are not going to use your QED for even a few months I advise that you remove the fuse to prevent slow discharge to a point where they cannot be recovered.

Cheers Goldman

That is good to know Goldman.

Also isn't there a certain voltage that the lithium batteries need to be set too if stored longer than 3-4 months?

Hi all,

For the most part, the maximum time for 18650 storage before recharge is about one year.
If you are intending long term 18650 storage, a storage charge closer to 50% of usable capacity (~3.7V) rather than 100% (4.2V) will prevent faster battery degradation.

50% = 3.64-3.71

Factory Preset Values and THS-B
Once you do a factory preset, all setting values will reset to their default values, including THS-B.

50 is the default factory preset for THS-B, but be aware that 50 is not necessarily the THS-B NULL point (for your QED).

If your QED THS-B NULL is not 50, then it may be noisy detecting using the factory preset values until you adjust THS-B to your normal ‘detecting’ setting.

I have seen QEDs with their NULL at 44, so doing a factory reset with THS-B at 50 will most definitely create noise as 50 is way above the QED’s NULL.

Just something to be mindful of when you are out and about finding gold in our fantastic goldfields.

Charging the QED battery extender pack

If you have the battery extender pack attached and connected to the QED, and the batteries are ‘flat’ after having been used to their detecting capacity, then be aware that when being charged by the standard (supplied) charger, the charger will get quite hot and stop charging.

After it has cooled sufficiently, the charging cycle will recommence.

Nothing to worry about, but obviously it will take longer to charge than anticipated.

Cheers
