Best DEWALT Battery Chargers in 2022

DEWALT Battery Chargers

DEWALT Battery Chargers are a great way to keep your cordless tools powered up and ready to go. These chargers were sold nationwide in 1996 and 2000 for $50 to $60. They were often sold in pairs with the cordless tools made by Black & Decker or DEWALT. Now, the battery chargers are sold separately. Read on to learn more. There are four modes to choose from: Maintenance, Equalization, Red light, and Lithium-ion.


For optimal battery performance, DEWALT battery chargers feature a Tune-Up(tm) mode. This automatically balances the cells of the battery to run at maximum capacity. During these tune-ups, DEWALT recommends performing the maintenance process once a week, or every ten to 20 charge cycles. To do a tune-up, remove the battery from the charger, wait a few minutes, then plug it back in.

After the charger is disconnected from the cordless drill, remove the battery from the battery. If the battery is cold, hold the trigger down to release the charging button. If the battery has already warmed up, you may leave it on the charger overnight. If you're not using it during this period, remove it and replace it with another fully charged backup battery. Make sure to follow these steps to prevent overcharging.

Cleaning the contacts on the DeWALT battery charger is important for proper functioning. Dust, dirt, and grime can collect on the contacts and reduce the battery's capacity. Once these components are cleaned, connect the tool to the charger to test the charge. Charging slowly using mini boosts will wake up the slumbering battery and increase its capacity just enough to use the tool. Make sure to read the manufacturer's instructions for proper charging and maintenance.

If you are unable to find a replacement battery within the warranty period, you can try the DIY option. To check whether your battery is dead, remove the battery panel and inspect the battery's interior for corrosion. To test the charger, use another fully charged battery for a better idea. However, if you find that your battery is no longer functioning properly, it's time to contact your DEWALT dealer.

Equalization mode

When using the Equalization mode on a DEWALT battery charger, you should leave the battery in the charging chamber for about one hour before removing it. This is because the equalization cycle will take an hour. If the battery is not fully charged, the charger may be able to complete the cycle in less time than you anticipate. In addition to charging, the Equalization mode allows your battery to be left in the charger for two hours or more, depending on the specific charger you are using.

Equalization mode is an automatic feature on most DEWALT battery chargers. It works by holding the battery's maximum voltage while recharging. The charger must reduce its current to less than ten percent of its output. Otherwise, it will automatically transition to float mode. Equalization is especially useful for wet batteries because the electrolyte will stratify over time if not cycled periodically. Equalization voltage is usually brought to 15 or 16 volts in a 12 volt charger and held for a period of time. This equalization stage helps to equalize the electrolyte strength and knock loose sulphation from the plates.

The Equalization mode on DEWALT battery charger is also an excellent option for maintenance. It ensures that the battery maintains its optimum performance by balancing individual cells. DeWalt recommends tuning up the battery once per week or every 10 to 20 charge cycles. If you have been using the battery for a while and noticed that it has lost its capacity, you can easily switch to this mode.

Red light

Some DEWALT battery chargers have indicator lights that flash. The red light means that charging has stopped, but this doesn't necessarily mean that the battery has failed. In fact, the red light can mean a number of things, including overheating or overloading. In this case, the charger will stop charging and delay the process. If this happens, it can be a good idea to disconnect the battery pack and remove it from the charger. You can then clean the battery pack's metal contact terminals to remove corrosion and then recharge it again.

Another sign that your battery is low is the red light. A smartphone battery will flash three times before turning off. A DeWALT battery charger has a microprocessor and memory and will automatically shut down if it detects a battery in danger of being overcharged. A simple reset of this indicator can allow it to charge properly and continue charging. It's worth avoiding any situation where you think you might overcharge a battery and run the risk of damage.

In most cases, a flashing red light means that the battery is in the charging phase. When the battery is fully charged, the yellow light will turn off, but a blinking red light could also mean that the charging process is suspended. In both cases, it's best to consult the manual to find out how the light signals different things. In most cases, the red light indicates that charging is in progress while the yellow light means that it's not.

The red light on a DeWalt charger is a helpful indicator that tells you whether the battery is full or not. The LEDs on your DeWalt charger should be blinking in the same way. In some cases, a flashing red light means that the battery is fully charged, but this isn't always the case. Always read your manual carefully before using a new DeWalt battery charger.


If you've ever used a lithium-ion battery, you'll know that charging it the wrong way can shorten its lifespan. Unlike batteries with traditional cathode materials, lithium-ion batteries have a capacity that lags behind its voltage. The best way to extend battery life is to charge them at a lower voltage. The trick is to avoid overcharging them - because going over the specification will lead to safety compromises.

DeWalt Lithium-ion battery chargers are designed to quickly and easily recharge your batteries without the hassle of a cord or a wall outlet. This convenient charger charges your batteries in just one hour or less. This charger features a built-in diagnostic system and an LED indicator that communicates the charging status and battery temperature. The DCB101 is one of the most powerful chargers on the market, capable of charging DEWALT Lithium-ion batteries and other tools with up to 20-volt capacity.


When recharging your cordless tools, you should consider using a Nickel-Cadmium battery charger from DEWALT. These chargers will recharge batteries that use the same chemistry, series, voltage, and battery type as your DEWALT tools. If you're considering buying a battery charger for your tools, you should first understand the differences between the different types. To help you find the best battery charger for your tools, follow these tips to keep your batteries in good shape.

The DeWALT DC9310 is a three-stage charger for 7.2 to 18-volt NiCd/NiMH/Li-ion batteries. It features a diagnostic LED indicator that lets you know how much charge your batteries have received. The charger will also tell you when it's time to replace the battery pack. Another advantage of the DC9310 charger is its compact design. It weighs only 3.0 pounds, and it works on all types of DeWALT batteries.

The most advanced chargers don't use a fixed temperature threshold, but instead use delta temperature over time. This keeps the battery temperature lower than the fixed temperature cutoff while maintaining full charge. It also offers timers and other functions to prevent overcharging. If you're not sure which charger will best suit your needs, consider reading online reviews to find out how these tools perform. They'll save you time and money.
