When the positive battery terminal is made up of aluminum, the corrosion particles are white it indicated the indicating the presence of aluminum sulfate. First, try removing and reinserting the drill battery into the charger. The increased internal heat of the battery may cause thermal runaway. I can either stop pulling things apart at this point and rebuild the pack, or I can keep going. Well, not quite, but that math works with their admittedly creative naming for this series of packs (personally, Id call it an 18.5V pack, but thats not a substantial improvement over the old 18V NiCd or NiMH packs - you can buy straight through adapters). This means the power delivered is less than the output the battery is capable of giving. I built a custom harness for my ZB206+battery tester (this is my go-to tester for single cell testing, but the cells are too long for my normal test fixture), and measured pairs of cells (because Im not ripping the pack apart that far). 3. Im going to grumble a bit here. These are hardcore power cells - a single cell at 30A is putting out over 100W! C3: 12.26V (4.09V) Categories Dewalt, DIY, Electronics, Power Tools.
