Maintenance and Care

Cross section of M18 12AH Battery

Maintaining your Milwaukee M18 12.0 Battery is crucial to ensure its longevity and optimal performance. Here are some key maintenance and care tips, incorporating the provided information:

  1. Proper Storage: Store battery packs in a dry, room-temperature environment to prevent moisture-related terminal corrosion, which can negatively impact battery performance. Additionally, avoid exposing batteries to high temperatures above 49°C (120°F) for extended periods to prevent permanent capacity loss and maintain overall battery lifespan and effectiveness.
  2. Regular Charging: Charge the battery before it completely drains. Lithium-ion batteries perform best when kept charged. Deep discharges can be harmful and may contribute to capacity loss over time.
  3. Use the Right Charger: Always use a compatible Milwaukee charger for your M18 12.0 Battery. Using the correct charger ensures safe and efficient charging. Avoid using third-party chargers that may not meet Milwaukee's specifications.
  4. Keep Contacts Clean: Periodically inspect the battery's contacts and the contacts on your tools for dirt or debris. Use a clean, dry cloth to wipe them clean gently. Dirty contacts can hinder charging and reduce performance.
  5. Follow Manufacturer Guidelines: Always follow the manufacturer's guidelines and battery care and maintenance recommendations. Milwaukee provides specific instructions in their user manuals, which should be your primary reference.
  6. Replace When Necessary: Monitor your battery's performance. If you notice a significant drop in runtime or other issues, it may be time to replace the battery. Over time, batteries can degrade, and replacement ensures continued tool performance.

Important Note

Immediately after using the battery pack, the Fuel Gauge may display a lower charge than it will if checked a few minutes later. This is because the battery cells "recover" some of their charge after resting.

By incorporating these maintenance and care tips, you can ensure that your Milwaukee M18 12.0 Battery remains in top condition, providing reliable power for your tools and extending its lifespan. Proper care maximizes your battery's performance and contributes to safer and more efficient work on-site.
