Yes, that battery is perfect but $22 ea is v expensive. I normally get them from Lanplus Australia. Looks like they are OOS but they have the Sony VTC range for $14 ea.This looks like my best option,

Just for others info, since the ML cell is 65-66mm long it is unlikely to be a "protected cell" as protected cells are closer to 68mm as they have a small BMS PCB on the end.
For this application you DONT want the type of cells with a built in BMS PCB ie( battery management system printed circuit board) as they will get confused with 4 of them acting independently.
battery welder will pay for itself over and over again - wait until you start repacking your $250 Makita 18V 5Ahr batteries for $90...

I hope I didn't make a blunder. I bought the AliExpress ones, 4 for $14.56 along with the welder.
At that price they prob wont last as many cycles as an 1st grade cell but only one way to find out.
At worst it will be good battery spot welding practice.
Just make 100% sure you know which wires go to which cells + & - .
I like to mark the wires with blue/red/black/white artline in unique stripes and take photos from a few angles BEFORE I desolder them so I have a reference.
Actually i wouldnt even try and use the $3.50 Aliexpress ones for the AEG battery packs as, unlike the 6000,which is only drawing 750mA, drills etc draw high current and unless they are decent cells they will be stuffed in a couple of cycles.
For interest, like the GPX6000 battery , the SDC lithium battery pack is also just 4 x 18650 cells but why charge people $80 (SDC battery) when you can charge them $240 (GPX6000)?

yep 18650 with tags is much easier then the button tops to do the replacement, just follow the way they have them setup and you'll be fine.This looks like my best option,

those ones your looking at 3400mAh and when link 2 in parallel gives you 6800mAh of run time at 1mAh per hour and seeing the detector don't use 1mAh per hour you will get about the same run time.
And the volts at 3.6v when you link 2 of them together in series you get 7.2v which will give you the same as the originals
so you have 2 of them in parallel and 2 of then in series and it all works out ok
