In this article, we will explore the details of Dewalt’s battery types, their technology, advantages, and why making an informed choice is crucial for your projects.
The Basics of Dewalt 20 Volt Batteries
DeWalt offers a range of 20 Volt batteries designed to power its extensive product lineup, from drill/driver combos to saws and beyond. But what exactly does “20 Volt” mean, and what type of battery technologies support this voltage?
What Does 20 Volt Mean?
The “20 Volt” designation refers to the nominal voltage of the battery. In the case of a lithium-ion battery, the nominal voltage can vary. Typically, lithium-ion batteries operate at about 3.7 volts per cell. Consequently, a 20 Volt battery usually consists of multiple cells connected in a series configuration.
- Battery Configuration: A typical 20 Volt lithium-ion battery is often made up of 5 cells (3.7V each), giving a total of approximately 18.5 volts
- Real Voltage: When fully charged, the voltage can rise to about 21 volts, thus marketing them simply as “20 Volt” batteries.
Are Dewalt 20 Volt Batteries Lithium-Ion?
The answer is a resounding yes. Dewalt 20 Volt batteries are predominantly lithium-ion, offering numerous benefits compared to other battery technologies, including nickel-cadmium (NiCd) or nickel-metal hydride (NiMH).
Why Choose Lithium-Ion Batteries?
Lithium-ion technology is widely regarded as superior for power tool applications. But what makes it stand head and shoulders above the rest?
Key Advantages of Lithium-Ion Batteries

Can I leave my Dewalt 20 Volt battery on the charger overnight?
While Dewalt chargers are designed with mechanisms to prevent overcharging, it is still advisable to avoid leaving batteries on the charger for prolonged periods, such as overnight, as a best practice. Frequent extended charging can potentially lead to performance issues over time, and it’s better to remove the battery once it reaches a full charge. This practice helps maintain the overall health of the battery.
If you occasionally forget to remove the battery, it typically won’t cause immediate damage, but regular habits of prolonged charging should be avoided to preserve battery life. To prevent such scenarios, consider charging your batteries during your active hours or set reminders to check on them, ensuring they are only on the charger as needed.
How do I store my Dewalt 20 Volt batteries properly?
Storing your Dewalt 20 Volt batteries correctly is crucial to maximize their lifespan and performance. Ideally, batteries should be stored in a cool, dry environment away from direct sunlight or extreme temperatures. Keeping them in temperature ranges between 32°F (0°C) and 70°F (21°C) is ideal as it helps maintain optimal performance and avoids potential damage.
It’s also a good idea to partially charge the battery before long-term storage. Storing it at around 40%-60% charge can help preserve its capacity better than fully charged or completely discharged states. Remember to periodically check on stored batteries and recharge them as needed to maintain optimal performance when you’re ready to use them again.
