●      Red & Yellow

When you insert the discharged battery into the charger and the solid red and solid yellow light illuminate simultaneously, it indicates the hot and cold delay. It means your battery temperature is extremely hot and hot, and it’s unable to hold a charge. The charging starts automatically when your battery reaches the standard temperature range.

●      Yellow (Blinking)

After insertion of the battery, if the yellow light blinks continuously, it indicates the problematic battery or charger. There might be any insertion issues or other problems with the battery. Therefore, sort out the problem and connect the charger again.

What If Your Battery Doesn’t Charge at All?

The hot and cold issue solves automatically when the battery contains a balance temperature range, neither too high nor too low. But what if your battery doesn’t charge at all? There might be some other reasons behind this issue. There might be some minor issues that you can solve by yourself in seconds.

On the other hand, there might be some major issues like a bad thermistor or damaged internal components and chips. You can solve these major issues as well if you have technical or electrical knowledge.

Otherwise, you should contact an expert technician or, in the case of a hand warranty, contact the DeWalt customer support services. Here are some quick solutions to fix the minor issues if your DeWalt battery is not charging properly.

1- Well-functioning Power Outlet

While plugging in the charger in the wall socket, make sure that the wall socket should be well functioning. It’s the first and foremost step you should take while connecting any electronic device. Maybe it’s the cause behind the malfunctioning of the battery or charger. Assess it and plug in the gears to other outlets.

2- Clean Dirty Terminal

Clean the terminals of the battery and charger to make them work well. Sometimes dust, debris, and corrosion accumulate on metal terminals due to prolong usage or not being used for extended periods. Clean the metal terminals with a Q-tip and rubbing alcohol or sandpaper.

3- Compatibility of Charger and Battery

Before inserting the battery into the charger, check out the compatibility of both the battery and charger. The charger should have the same voltage in accordance with battery capacity. Don’t insert the incompatible battery into the charger. It may cause damage to the metal terminal or plastic casing of the battery as well as the charger. That’s why don’t force the battery into the un-compatible charger.

4- Proper Insertion

After assessing the compatibility, be careful while inserting the battery into the charger. Fix it properly in the charger’s railing until you hear an audible click sound. If you don’t insert the battery properly, both gears’ metal terminals can’t connect, and the charger indicates charging issues.

5- Malfunctioning of Charger/Battery

If the battery is still not holding a charge, check out which is responsible for malfunctioning, either the charger or battery. To assess it, put in the other DeWalt battery to the charger. If the battery begins to charge, it means the charger is functioning properly and the battery is faulty. Contrarily, if the other battery doesn’t hold a charge, the charger is the culprit. It might be possible the other battery is also faulted. Although it’s an occasional situation that both batteries are dead and faulted. If the charger is at fault, you can charge the DeWalt battery without the charger as well.

6- Jump Start the Battery

Despite applying all strategies, if your battery still doesn’t hold, jump-start it using another DeWalt battery or car battery.

7- Keep the Temperature Moderate

If you face hot and cold delay issues, try to moderate its temperature. If the battery cools down, try to heat it, or if it’s too hot, decrease the overheating to the normal temperature range.

8- Repair the thermistor

The thermistor is a temperature-controlling component built into your DeWalt charger and battery. If it’s malfunctioning, the battery shows the extreme temperature without being too hot or too cold. Check the temperature of your battery; you can use a thermometer or temperature sensor. To check it, you have to tear out the external casing of the battery.

The thermistor is located along with the positive terminal of the battery and charger. Place the testers on the thermistor and analyze the temperature. If there is any issue, you can troubleshoot this issue by repairing or replacing the thermistor.

Pro Tip: To troubleshoot thermistor issues, you should have technical knowledge or practical experience. Otherwise, contact the expert technician.

How Should a DeWalt Battery Be Stored?

You should store the battery in a cool, dry place. If you want to save from the hassle of extreme temperature, save your battery at an appropriate place where the atmosphere is neither too hot nor too cold.

Don’t store or use the battery pack in extremely hot and cold locations where the temperature may reach or exceed 40 ˚C (104 ˚F). Additionally, keep your battery pack stays out of metallic objects. Don’t keep them in the toolbox and kits to prevent the exposed battery terminals from nails, screws, and keys.

Pro Tip: The recommended temperature to store the battery is neither below 22 ˚C nor high than 40 ˚C.

Electronic Protection System for Batteries

Electronic Protection System (EPS) is a processor-controlled system that is built into the DeWalt Batteries. This mechanical security system controls the internal mechanism of the DeWalt battery efficiently. It not only prevents the battery from overcharging and overheating but also extends the lifespan of the battery to its maximum. It usually controls the following operations of the battery:

1- Temperature

EPS manages the battery’s temperature while using the tool or charging in the charger. It helps to maintain the battery temperature to the standard level and prevent it from overheating during heavy-duty applications and working on larger workpieces.

2- Voltage

EPS controls the voltage of the DeWalt battery to increase and decrease from its required voltage rating. Usually, the cutdown value of each Lithium-ion battery cell is a nominal 3.0V and a maximum of 4.2V. When these voltages try to increase while charging and decrease while discharging, the battery shuts down due to fabulous EPS.

3- Current

EPS manages the battery output while using it in the tools and input current as well while charging it. The EPS keenly analyzes the tool requirement in which you are using the specific battery. It helps the battery deliver the required output, whether too low or too high. In this way, EPS saves the battery from overloading as well as overheating because both of these are the most hazardous and shorten the lifespan of your DeWalt battery.
