  2. Dip an old toothbrush or cloth into the solution and scrub the terminals.
  3. Rinse with clean water and dry thoroughly.

This method will ensure improved electrical contact during charging.

Step 3: Charge the Battery

Using a charger compatible with your battery type, plug it in and charge the battery. For NiCd batteries, perform a full discharge followed by a complete charge cycle, as this can help recondition the cells. Conversely, NiMH batteries require a gentle charge, so avoid fast chargers if possible.

Step 4: Conduct a Load Test

After charging, it’s important to conduct a load test. This is where you determine how well the battery performs under pressure. Here is what you’ll do:

  1. Connect the battery to a tool that uses a comparable load.
  2. Observe how the battery performs. If it runs the tool smoothly for a reasonable time, it is likely revived.

Step 5: Store the Battery Properly

Proper storage is vital for maintaining battery health. Store the DeWalt 12-volt battery in a cool, dry place and avoid extreme temperatures. Ideally, keep the battery partially charged, around 50-70%, if it’s not going to be used for an extended period. This can help prevent further self-discharge.

Tips to Extend Battery Life

Once you have revived your battery, you want to ensure it remains functional for as long as possible. Here are some tips to help you extend its lifespan:

Regular Maintenance

Just like any piece of equipment, regular maintenance is essential. Continually check for corrosion, clean terminals, and monitor the battery’s performance over time.

Avoid Frequent Deep Discharges

Both NiCd and NiMH batteries benefit from being charged before they are completely drained. Frequent deep discharges can weaken the battery cells, decreasing their ability to hold a charge.

Temperature Awareness

Temperature plays a significant role in battery health. Avoid exposing batteries to high heat or extreme cold and always use them within their operating temperature range, typically between 50°F and 86°F.

Keep Batteries in Pairs

If you have more than one DeWalt 12-volt battery, consider using them in pairs to maintain a consistent performance level. Regularly switch between batteries to ensure even wear.

When to Consider Replacement

Not all attempts at revival will succeed. If after multiple charging cycles the battery consistently exhibits the same symptoms or shows no improvement, it may be time to consider purchasing a new battery. This is particularly true if you notice physical damage such as bulging or it simply doesn’t hold a charge.

Finding Replacement Options

If you reach the conclusion that you need a new battery, consider these options for purchasing a replacement:

Option Description
Authorized Dealers Purchase directly from DeWalt’s authorized retailers or their official website to ensure authenticity.
Online Marketplaces Sites like Amazon or eBay often have a range of batteries available, but ensure you check seller ratings.

Always confirm that the replacement battery matches your tool’s specifications to ensure compatibility.
