Enhancing Battery Longevity

Properly maintaining and taking care of your Dewalt 20V batteries is essential to ensure their longevity and optimal performance.

By following the right storage and charging practices, you can make the most out of your batteries and prolong their lifespan.

Proper Storage

  • When storing your Dewalt 20V batteries, it is crucial to keep them in a cool and dry environment, away from direct sunlight and excessive heat or cold.
  • Avoid storing the batteries near flammable materials or in areas with high humidity, as these conditions can negatively impact their performance.
  • Store the batteries in a secure place where they won’t be subjected to physical damage or accidental drops, as this can result in a shortened lifespan.
  • Make sure to remove the batteries from your power tools when not in use to prevent any drain or discharge over time.

Optimal Charging Practices

  • Always use the appropriate Dewalt charger specifically designed for your 20V batteries to ensure compatibility and safe charging.
  • Before charging, check for any dust, debris, or corrosion on the battery terminals and clean them if necessary to ensure a proper connection.
  • Avoid overcharging your batteries. Once they reach their full capacity, promptly remove them from the charger to prevent any potential damage or overheating.
  • On the flip side, don’t let your batteries fully discharge before recharging them. Regularly topping them off or charging them when they have around 20-30% capacity left can help maintain their performance and longevity.
  • If you expect not to use your Dewalt 20V batteries for an extended period, charge them to around 50% capacity before storing them. This will help preserve their overall health and prevent premature aging.

Incorporating these storage and charging best practices will significantly contribute to maximizing the lifespan and performance of your Dewalt 20V batteries.

By properly maintaining them, you can rely on your batteries for prolonged use and get the most out of your power tools.
