Setup

Charging the Battery

Before first use, it is recommended to fully charge the battery pack. Ensure you are using a charger compatible with 12V Ni-Mh batteries, such as the original Dewalt charger for DW9050/DW945 series tools.

1. Connect your compatible battery charger to a power outlet.
2. Align the battery pack with the charging port on the charger.
3. Slide the battery pack firmly into the charger until it clicks into place.
4. Observe the charger's indicator lights for charging status. Refer to your charger's manual for specific light patterns.
5. Once fully charged, remove the battery from the charger. Avoid leaving batteries on the charger for extended periods after they are fully charged.

Operating Instructions

Once the battery is fully charged and securely installed in your compatible Dewalt power tool, it is ready for use. These batteries are designed to provide consistent power for your drilling, driving, or other applications.

• Operate your tool as per its original instruction manual.
• The battery's 2000mAh capacity provides ample runtime for typical tasks.
• When the tool's performance begins to diminish, it indicates that the battery charge is low. Recharge the battery promptly.
• Avoid completely draining the battery, as this can reduce its overall lifespan.

Maintenance

Proper maintenance will extend the life and performance of your ExpertPower Ni-Mh battery packs.

• Cleaning: Keep the battery terminals clean and free of dirt or debris. Use a dry cloth to wipe them if necessary.
• Storage: Store batteries in a cool, dry place away from direct sunlight, heat sources, and moisture. For long-term storage, it is best to store Ni-Mh batteries with a partial charge (around 40-50%) rather than fully charged or completely discharged.
• Regular Use: If storing for extended periods, it is advisable to cycle the battery (charge and discharge) every few months to maintain its capacity.
• Avoid Impact: Do not drop or subject the battery to strong impacts.
