With the temperature hovering around 46°C it was not a good day to be outside. I started the morning by fitting a new 7-pin trailer socket to the back of the bus. The old one was working but had lost the little screw that keeps the inside inside.
After I got up from my afternoon snooze, two hours of it, I looked around for something I could do inside. The GPX6000 battery rebuild came to mind. I couldn't work outside so while Mrs M was engrossed in a jigsaw puzzle I brought the tools into the dining room table.
The first thing needed is the tamper-proof Torx key.
Inside the batteries have four wires. Three soldered onto the circuit board and one sense wire just glued to the negative wire.
With the battery pack removed the housing can be put aside.
I probably went a bit cheap on the replacement batteries. I paid $21.59 for four batteries.
I didn't spend much on this project because it was a practise run and the GPX6000 battery pack was done anyway.
I have the new spot welder but just to be be sure I connected the batteries by their wires first. After that I spot welded the nickel straps and soldered the three wires back to the circuit board. Then it was just a case of close it up and put it on charge.
I spent $36.99 on the spot welder, $7.25 on a couple of heavy duty bulldog clips and longer cables to connect the spot welder to the N70Z 12V battery and $21.59 for four lithium batteries. A total of $65.83
It's now outside on charge. When tested with the multimeter all the old batteries were fully charged however they would be flat in five minutes when installed into the detector. I've been charging the GPX6000 battery with a cigarette lighter plug but recently both batteries have been finishing with the red fault light on. That prompted me to get the red and black charge cable that was supplied by Minelab to charge the better of the two batteries. This cable has to be clamped directly onto a 12V vehicle battery. Using the originally supplied charger the green light was illuminated when charging was done and that battery lasted its full term.
