Battery terminal faulty? It's time to face the fix. Whether you are a master carpenter or an occasional drill-seeker, eReplacementParts.com provides the parts, procedures and facts you need to fearlessly fix what fails you.
The terminal is the attachment point for the battery on your cordless drill. It is a plastic block with metal spades, which engage the contacts on the battery. If there is a short within the battery, or if the drill is badly overheated, the terminal can be damaged. Look for signs of melted plastic around the metal spades. In some cases, the spades themselves will be melted or discolored from excessive heat.
The wire connections (between the terminal and the switch) are another issue involving the terminal. Make sure the connections are tight, and that there is no corrosion between the wires and the terminal.
