DEWALT FLEXVOLT Battery Problems & How To Fix Them

Are you wrestling with a DeWALT FLEXVOLT battery that won’t charge?

I completely understand the frustration. There’s nothing more aggravating for a woodworker than reaching for your power tools, ready to dive into an important project, only to find them powerless. It’s a setback that can throw a wrench in your workflow.

Fortunately, you’ve landed on the right page for a solution.

What Are DEWALT FLEXVOLT Batteries?

The FLEXVOLT battery system is unique in that it can power both 20V MAX and 60V MAX (or 54V) DEWALT tools, providing versatility and reducing the need for multiple batteries of different voltages.

3 Common DEWALT FLEXVOLT Battery Problems

Even the most reliable names in power tools, like DEWALT, aren’t immune to the occasional hiccup, and it seems a few battery issues have become common talking points among woodworking enthusiasts.

Let’s explore the 3 primary types of reasons you might face with your DEWALT FLEXVOLT batteries.

Battery Won’t Charge

It’s the number one gripe: a battery that refuses to charge. If you’re facing this, you’re not alone.

• Inspect the Battery Terminals: Begin with the basics. A thorough inspection and cleaning of the battery terminals can often resolve charging issues.
• Check the Battery’s Fit in the Charger: Ensure that the battery is properly and fully seated in the charger. It should fit snugly without any wiggle room.
• Use the Correct Charger: Confirm that you’re using the designated charger for your battery. Compatibility is key to effective charging.

These steps might seem straightforward, but they’re often the most effective starting point for troubleshooting.

battery charge does not last long

Navigating a battery that won’t hold its charge can be a major roadblock in your woodworking projects, but there are a few strategies you can employ to address this issue.

• Skip the Top-Offs: Use the battery until it’s low but not completely dead to prevent damage.
• Let It Rest: Before recharging, let the battery cool to room temperature.
• Charge Thoroughly: Give it a full overnight charge for maximum power recovery.
• Evaluate Battery Condition: If problems persist, the battery may be damaged or worn out. For newer batteries, consider contacting DEWALT for a potential replacement.

battery is not working at all

If your battery won’t charge or hold a charge at all, it’s likely reached the end of its life, and it’s time to invest in a new one.

But before you do, test the power tool with a spare battery (it’s always wise to have one on hand). If the spare powers up the tool without issue, then the original battery is the culprit.

Batteries, like all things, have a limited lifespan, and once they’re spent, replacement is your next move. Repair isn’t on the table for a battery that’s given its all.

Resetting Your DEWALT FLEXVOLT Batteries

When your DEWALT FLEXVOLT battery isn’t performing as expected, a reset might be just what it needs to get back to its optimal state.

Here’s a quick guide to resetting your battery:

1. Detach the Battery: Remove the battery from the tool or charger to ensure it’s not receiving any power.
2. Cool Down: If the battery is warm from recent use, allow it to cool to room temperature.
3. Discharge: If possible, use the battery in your tool until it stops operating to fully deplete its charge.
4. Wait it Out: Leave the battery disconnected for about an hour to let its internal circuitry reset.
5. Recharge: Place the battery back in its charger and allow it to charge completely.

DEWALT Charger Troubleshooting

1. Power Source: Confirm the charger is connected to a working outlet.
2. Physical Inspection: Quickly check for any signs of damage on the charger.
3. LED Indicators: Refer to your manual to decode the LED signals.
4. Contact Points: Clean the charger’s contacts as you would with the battery terminals.
5. Compatibility Check: Make sure the charger is intended for your specific FLEXVOLT battery model.
6. Environmental Conditions: Operate the charger within the recommended temperature range.
7. Alternate Battery Test: If possible, try charging another battery to isolate the issue.

Battery Maintenance Tips

1. Optimal Charging: Charge your batteries at room temperature and avoid leaving them on the charger for extended periods after they’re fully charged.
2. Proper Storage: Store batteries in a cool, dry place, away from metal objects. For long-term storage, keep them at a 30-50% charge level.
3. Regular Cleaning: Wipe the battery terminals with a clean cloth occasionally to prevent build-up of dirt and debris.
4. Usage Cycles: Use your batteries regularly to prevent them from remaining dormant, which can affect their lifespan.
5. Avoid Extremes: Keep batteries away from extreme heat and cold, which can damage them over time.
