in fact i have one at home and would like to test for you as long you can give me clear instructions which ones are the pins to charge the battery with.
cause i remember the middle ones you mentioned are +/+ in polarity that means it cant be charge putting them in the middle right.
Basically the battery inside had three plates, i need to know which one are minus and plus and then know which one outside are running parallel to it.
I think the other two remaining are for data purposes.
I think we may have been at cross-purposes, but not to worry, we can still help.
I was looking to make an alternate charger while the battery was inside the TS - I think you are wanting to charge the battery outside?
The device you posted - it looks like it has 4 pins as outputs, and the levers used to set a voltage to each one - yes?
What is the distance between each pin - does it look as though the TS (not the battery) could sit on top and all the connections meet?
Anyway, to answer your question, Ive attached a couple of picture of the battery only - it shows the max charging voltage, in case yours doesnt.
I used a meter to test the voltage of the battery - as far as I can tell, the middle pin is not used, so you may be able to get away with just applying a voltage to the other two. It may be the middle one is used as a control - to send a stop charging message for example.
I have now got the SUUNTO clip working with just 0V and +5V to the outside pins - its all about lining them up properly!
