The key to your tool’s full potential is its battery. The BLACK+DECKER 20V MAX* 20v lithium battery delivers superior power, longer runtime, and unmatched convenience.
It is no surprise that lithium-ion cells now command over 62.43% of the market. This lithium technology is the trusted standard for performance.
This 20v battery enhances performance using its unique features. We will explore how the power of this 20v lithium battery comes from its core design. This 20v lithium battery provides consistent power.
Core Technology That Enhances Performance
The foundation of the 20V MAX* system is its advanced lithium-ion technology. This core design is what truly enhances performance for every project. The high-quality lithium cells inside each 20v lithium battery pack more power into a compact space. This specific technology provides the muscle behind your tools.
Achieving Longer Runtime and Fade-Free Power
Older battery types often lose power as you work. Your tool starts strong but gets weaker, slowing you down. The 20v lithium battery solves this problem with fade-free power. The lithium-ion technology delivers consistent, reliable power throughout the entire discharge cycle. Your tool works at full strength until the battery is nearly empty.
This superior performance comes from a höhere Energiedichte. The BLACK+DECKER 20V MAX* lithium-ion battery stores more power in a smaller, lighter package compared to old Nickel-Cadmium (NiCd) batteries. This key feature means you get a longer runtime per charge. A lighter battery also reduces fatigue, so you can work comfortably for longer periods. The advanced lithium design ensures you get more work done with every single charge.
Maintaining Consistent Speed and Torque
Consistent power directly translates to better tool performance. A steady energy supply allows your tools to maintain optimal speed and torque, even under heavy loads. The 20v battery is engineered to deliver its power evenly. This ensures your drill, saw, or sander maintains its performance from the beginning of a task to the end.
This lithium-ion battery design ensures your tools operate at peak levels until the charge is almost gone. For example, an impact driver using the 20v battery can provide maximum torque without extra strain on the user. The stable power output from the lithium battery means no frustrating power drops in the middle of driving a long screw or drilling a tough material. These features give you the confidence that your tool will perform when you need it most.
Reducing Downtime with Rapid Charging
Every minute spent waiting for a battery to charge is a minute you are not working. The 20v lithium battery system minimizes this delay with fast charging capabilities. Certain rapid chargers can replenish a 20v battery in 40 minutes or less. Some models can achieve a full charge in just 30 minutes.
Profi-Tipp: Need power in a hurry? Some rapid chargers offer a ‘flash charge’ mode. This feature can bring a depleted battery to 30% capacity in only 10 minutes, getting you back to your project with minimal interruption.
This rapid charging is possible thanks to smart technology that protects the battery. Modern chargers and batteries communicate to prevent damage.
- Batterie-Management-System (BMS): A sophisticated system inside the battery constantly monitors temperature and voltage.
- Thermal Management: The charger adjusts the power delivery if it detects unsafe temperatures. This intelligent charging process prevents overheating and extends the life of your lithium battery.
This combination of speed and safety enhances performance by keeping your tools ready for action.
Smart Features That Boost Your Workflow
Beyond raw power, the 20V MAX* system includes smart features designed to make your work easier and more efficient. These thoughtful details enhance the user experience from start to finish. The lightweight and compact design of the 20v battery is a perfect example of these user-focused benefits.
Lightweight Design for Better Handling
A heavy tool can cause fatigue quickly, making it hard to work accurately. The 20v lithium battery has a lightweight and compact design that reduces the overall weight of your tools. This lightweight build improves balance and makes tools easier to handle, especially when working overhead or in tight spaces. You can work longer and more comfortably with less strain on your arms and wrists. This lightweight power source gives you better control for more precise results.
Flexible Charging with No ‘Memory Effect’
Older Nickel-Cadmium (NiCd) batteries suffered from a “memory effect.” If you repeatedly recharged them before they were fully empty, they would “remember” the partial charge point. This process involved the growth of large crystals on the battery’s internal plates, which reduced the battery’s total capacity.
The modern lithium battery completely eliminates this problem. Lithium-ion chemistry does not form these performance-reducing crystals.
This means you can top off your 20v battery at any time without damaging its long-term health. This flexible charging capability is one of the most convenient features of the lithium battery, ensuring you always have full power available.
Grab-and-Go Readiness with Low Self-Discharge
There is nothing more frustrating than grabbing a tool for a quick job, only to find the battery is dead. The 20v lithium battery solves this with its extremely low self-discharge rate. Unlike older battery types that lose their power over a few weeks, a lithium battery holds its charge for months. This means your battery is ready to go when you are, even if the tool has been sitting on a shelf. This grab-and-go readiness provides reliable power for both frequent and infrequent projects. A smart Battery Management System (BMS) also protects the battery during storage by preventing over-discharging, which helps extend its overall lifespan.

Maximizing Your 20V Battery Lifespan
A powerful 20v lithium battery is a long-term investment. Proper care is essential to protect that investment and extend its battery life. Following a few simple guidelines for charging and storage will ensure your battery delivers reliable performance for years.
Using the Correct Charger for Safety
Always use the charger designed for your 20v battery. BLACK+DECKER® chargers are built to high safety standards. They communicate with the battery to prevent overcharging and overheating. Using third-party or non-specified chargers can be risky.
- They may lack proper voltage control.
- This increases the risk of overheating the battery.
- It can also lead to overcharging, which damages the lithium cells.
Sticking with the official charger is the safest way to protect your equipment and ensure a long battery life.
Avoiding Extreme Temperature Exposure
Temperature greatly affects a lithium-ion battery. Extreme heat and cold can cause permanent damage. High temperatures speed up chemical reactions inside the battery, which shortens its lifespan. Cold temperatures are also a problem, especially during charging. Charging a very cold lithium battery can cause “lithium plating,” a process that permanently reduces capacity.
Profi-Tipp: Never leave your batteries in a hot car or a freezing garage. Store your 20v lithium battery in a cool, dry place. The ideal storage temperature is between 15°C and 25°C.
Best Practices for Charging and Storage
Modern lithium batteries do not have a “memory effect.” You do not need to fully drain the battery before charging. In fact, it is better to perform partial charges. Recharging your battery when it reaches about 20% capacity is a good practice.
For long-term storage, do not leave your battery fully charged or fully empty. A battery stored at 100% charge loses capacity much faster than one stored partially charged.
| Temperatur | Recoverable Capacity at 40% Charge (after 1 year) | Recoverable Capacity at 100% Charge (after 1 year) |
|---|---|---|
| 25°C | 96% | 80% |
| 40°C | 85% | 65% |
The ideal state for storage is around 40-50% charge. This simple step significantly helps preserve the health of your lithium battery.
The 20V MAX* system is a smart investment for improved efficiency. The core lithium-ion technology and smart features deliver superior performance. This 20v battery enhances performance by providing more power and longer runtime. The POWERCONNECT™ system offers the convenience of a single lithium platform.
