2. Safety Instructions
WARNING: Failure to follow these safety instructions may result in fire, electric shock, personal injury, or property damage.
- Always use a charger specifically designed for NiCd batteries. Using an incompatible charger may damage the battery or cause a fire.
- Do not disassemble, open, or shred battery packs.
- Do not expose batteries to heat or fire. Avoid storage in direct sunlight.
- Do not short-circuit a battery. Do not store batteries haphazardly in a box or drawer where they may short-circuit each other or be short-circuited by other metal objects.
- Do not remove a battery from its original packaging until required for use.
- Do not subject batteries to mechanical shock.
- In the event of a battery leaking, do not allow the liquid to come into contact with the skin or eyes. If contact has been made, wash the affected area with copious amounts of water and seek medical advice.
- Keep batteries clean and dry.
- Do not use any battery pack that is not designed for use with the equipment.

4. Setup
4.1 Initial Charging
Before first use, it is recommended to fully charge the batteries. NiCd batteries often benefit from a full charge/discharge cycle to reach their optimal capacity. Use a compatible 12V NiCd battery charger.
4.2 Battery Installation
- Ensure your DEWALT DW945 cordless drill or compatible tool is turned off and disconnected from any power source.
- Locate the battery compartment on your tool.
- Align the Banshee 12V 2AH NiCd battery with the battery slot, ensuring the terminals match correctly.
- Slide the battery firmly into the compartment until it clicks securely into place. Do not force the battery.
- To remove the battery, press the release button (if present on your tool) and slide the battery out.

5. Operating Instructions
5.1 Charging the Battery
Always use a charger compatible with 12V NiCd batteries. Refer to your charger's instruction manual for specific charging procedures.
- Insert the battery into the charger.
- Connect the charger to a power outlet.
- Monitor the charger's indicator lights for charging status.
- Once fully charged, remove the battery from the charger. Avoid overcharging, as this can reduce battery life.
5.2 Using the Battery with Your Tool
Once installed, the battery powers your cordless tool. Operate your tool according to its specific user manual. When the tool's performance diminishes, it indicates the battery needs recharging.
6. Maintenance
6.1 Cleaning
Keep battery terminals clean and free of dirt or corrosion. Use a clean, dry cloth to wipe the battery casing and terminals. Do not use liquids or solvents.
6.2 Storage
For optimal battery life, store NiCd batteries in a cool, dry place away from direct sunlight and extreme temperatures. If storing for extended periods, it is recommended to fully discharge and then partially charge the battery (around 40-50% capacity) before storage. Recharge every 3-6 months to prevent deep discharge.
6.3 Battery Cycling
NiCd batteries can develop a 'memory effect' if repeatedly partially discharged and recharged. To mitigate this, occasionally perform a full discharge cycle (until the tool stops) before fully recharging the battery.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Battery not charging | Incompatible charger; faulty charger; dirty terminals; battery too hot/cold. | Ensure charger is compatible with 12V NiCd batteries. Check charger for damage. Clean battery and charger terminals. Allow battery to reach room temperature before charging. |
| Short run time after charging | Battery memory effect; battery nearing end of life; incomplete charge. | Perform a full discharge/recharge cycle. Ensure battery is fully charged. If problem persists, battery may need replacement. |
| Battery not fitting into tool | Incorrect alignment; debris in compartment. | Ensure correct alignment with tool's battery slot. Check for and remove any debris from the tool's battery compartment. |
