  • Digital communication within actively protects against overload, over-discharge and overheating

  • Impact-resistant housing and shock-absorbing liner designed to protect the battery

  • Sixteen contact terminals maintain a constant connection to the tool, helping to prevent power loss or fluctuation, even in high vibration applications

  • Batteries are resistant to self-discharge and can be used even after long periods of storage

Each battery pack is durably built for heavy-duty use, runs cooler, and performs in climates below 0°F/-18°C.
