Are your old explorers really dead?
« on: December 28, 2017, 14:34 »
I remember reading about a few people that have had their explorers sitting around gathering dust and after charging their batteries up getting no response from the machine.

This happened to me recently and after charging the battery pack for a while, then loading it into the machine I press the power button, get a bit of a chirp but nothing fires up.  

Thinking I had the dreaded 'Stored Explorer' curse I looked into the contact springs which seemed fine then as I anticipate things getting serious I pull out my multi meter and mini screwdriver set.

First check was battery pack, plenty of charge....better read the fine print on the pack I think to myself and then I realised it is storing a bit higher than the battery spec....brain starts ticking over and I decide to drain a little of the voltage off the pack back within something like 10% of spec, drop it in and it fires up as though nothing was wrong with it.

Conclusion:
I figured that I have overcharged the battery pack, by how many hours I dont know, but since the charge pack on the Explorer doesnt actually indicate when the batteries are fully charged (just shows power on) I figure this may not be too hard to do and others have done the same (particularly with older units, these days we tend to set and forget and get back to it when we remember).
So if this happens to you, Check the voltage on the battery to see if is within about 10% of the specs as the machine, expecting a set voltage range, will prevent the machine from firing up to protect its circuitry until the voltage is within range again.

Hope this helps others out there that think they could have a completely dead machine lying around when it could well be a voltage range issue.

Thanks for that, some good info to store in the back of the brain for when I eventually upgrade my Explorer and it starts to 'gather dust'.

It is annoying that the Minelab charger doesn't show when full charge is reached.

Thanks for the heads up goldnugget01. I tried firing up my SE a couple of months ago, when that happened. I thought the battery pack had gone bad. I had a spare pack that takes alkaline batteries, and it fired up OK. I’ll have to pull it out again and go for a hunt with it. Using the Garrett GTI atm.

I thought you were talking about blokes like Blaxland, Wentworth and Lawson, who I expect died a long time ago!

Thank You ivanll , I have not been busy lately on the detecting front so have had little to report but when I realised what happened to the machine and remembered others had fire up issues with their machines I figured I would share it.  
I know there are still people around the use Explorers (mine is a backup to the CTX) and would be a shame to have the machine binned for a simple fault/solution .

Really useful info. How do I drain the overcharged battery then?
