The interconnects here are thick, massive, and well spot welded. The B+/B- terminals look like copper to me, with the rest being brass or something along those lines. This post may contain affiliate links. Start with one end, pry (carefully - dont short the pack out), and it comes out. The last new-to-me pack I pulled apart was a 26v BionX battery(which, Id add, I rebuilt to nearly twice the stock capacity by filling all the space with cells). The pack claims to be 3.0Ah, which means each cell should be 1500mAh.

What Are The Effects Of Corrosion On The Positive Terminal? When the battery stays in a discharged or partially discharged state, sulfation is likely to occur and will lead to reduced battery capacity. This will lead to the battery being overcharged. Type 2, whatever that means. Looking at the discharge curves for the cell (from the previously linked PDF), Panasonic considers the cell fully drained at 2.5V - which is absurdly low for a lithium cell (and works out to 12.5V across this pack). Put the black lead of your voltmeter on the B- pin, and probe C1-C4 and B+ - you should see a steady increase in voltage as you go from terminal to terminal. C1, C2, C3, and C4 are direct access to the voltage of each cell group - so, as shipped, 3.5V per cell. This is on the back of your drills computer chip. And the rest isnt very pretty either. Beyond that, the switch, when pressed, applies pack voltage to a system that lights the proper LED based on the voltage. But, the terminals are live at all times - so I wouldnt want to carry this pack in a box full of paperclips, metallic tinsel, or other metal objects that could make contact with the terminals. They get beat on. The same variability which causes different run-times prevents our cells from developing memory. It would charge, but then only show one LED on the status bar.
