By applying a thin layer of petroleum jelly at the battery terminals and on the terminal connectors, you will form a protective coating around the terminal that will prevent future corrosion. Attach one end of the negative (black) jumper cable to the negative terminal. To clean the corrosion from the battery terminal you need to neutralize it with a basic solution then remove the corrosion. How? The increased internal heat of the battery may cause thermal runaway. New . It has the same terminals and latching mechanism as all the 20V Max packs - which does make sense, given that they all need to fit in the same tools.

What Happens If You Overfill The Battery? If the batteries are too hot (105F or higher) or too cold (below 40F), the batteries will not take a full charge. Its worth noting that the thermistor is showing the board temperature, not the cell temperatures. How To Prevent Corrosion On The Positive Terminal? Its less of a problem with this pack (as it never charges to full by the cell chemistry), but charge them, run a tool for a few minutes, then store them if its going to be a few months. Slick! The presence of corrosion is distinguished by the presence of a powdery substance at the terminal that may be greenish, blueish, or white depending on the metal used to make the battery terminal.
