Power Tool Batteries Guide
Battery capacity
The capacity of the battery refers to the amount of charge it can hold, typically measured in ampere-hours (Ah). The higher the capacity, the longer the battery will last before needing to be recharged. For example, the DEWALT DCB207 features a capacity of 1.3Ah, allowing for extended runtime on tools such as drills and screwdrivers. On the other hand, the Makita BL1850B offers a larger capacity of 5.0Ah, providing even longer usage before recharging, making it suitable for heavy-duty power tools like circular saws and angle grinders. Keep in mind that different power tool battery brands offer various capacity options, so ensure to check the product specifications for the desired capacity needs.
Voltage
Voltage, measured in volts (V), determines the power and performance of the battery. Higher voltage batteries generally provide more power and can handle tougher tasks. For example, the DEWALT DCB205-2 20V MAX XR Lithium-Ion batteries offer a voltage of 20V, making them suitable for high-demand power tools such as drills and saws. On the other hand, the BLACK+DECKER LBXR20 20V Max Lithium-Ion battery provides a similar voltage, making it an ideal choice for various DIY tools and cordless garden equipment. Remember that the voltage of the battery needs to match the specific power tool requirements for optimal performance.
Ampere-hour (Ah) rating
This rating indicates the amount of power the battery can deliver over a given period of time. Generally, the higher the Ah rating, the longer the battery will last before needing to be recharged.
In the market, power tool batteries can be divided into different groups based on their Ah rating. In the 12V segment, the DEWALT DCB122 offers an Ah rating of 2.0, providing ample power for light to medium-duty tasks. Moving up to the 18V segment, the Bosch BAT620-2PK features a higher Ah rating of 4.0, ensuring longer runtime and increased versatility for more demanding jobs. For heavy-duty applications in the 20V+ range, the Makita BL1840B-2 stands out with a large Ah rating of 4.0, delivering significant power and extended runtime.
It is worth noting that manufacturers often provide additional technical specifications for battery performance, such as voltage and watt-hour (Wh) ratings. These specifications can further complement the understanding of the battery's capabilities but are not the primary focus in this particular guide.
Compatibility with power tools
It's essential to find batteries that are compatible with your tools in terms of voltage, ampere-hour (Ah) rating, and battery chemistry. The voltage must match the requirement of your power tools, such as 18V or 20V. Make sure to check the Ah rating, which represents the battery's capacity for storing and delivering power. For instance, the DeWalt DCB240 is a compatible 20V Max 4Ah lithium-ion battery suitable for DeWalt power tools, while the Makita BL1850B is a 18V 5Ah lithium-ion battery specifically designed for Makita tools. Keep in mind that some battery types, such as nickel-cadmium (NiCd), nickel-metal-hydride (NiMH), and lithium-ion (Li-ion), may not be interchangeable, so ensure they are compatible with your power tools.
Battery type (lithium-ion, nickel-cadmium)
The two most common battery types for power tools are lithium-ion and nickel-cadmium.
Lithium-ion batteries are known for their higher energy density and lighter weight compared to nickel-cadmium batteries. They also have a longer lifespan and can hold a charge for a longer period of time. An example of a lithium-ion battery for power tools is the '`Makita 18V LXT Lithium-Ion Compact Cordless 2-Pc. The lithium-ion battery in this set has a high capacity of 2.0Ah, allowing for longer runtime and less frequent recharges.
On the other hand, nickel-cadmium batteries are known for being more durable and performing better in extreme temperatures. They also have a lower self-discharge rate when compared to lithium-ion batteries. A popular nickel-cadmium battery for power tools is the '`Porter-Cable PC18B 18-Volt NiCd Cordless Battery Pack'. It offers a high output voltage of 18 volts, providing ample power for various tools.
These two types of batteries cater to different needs and preferences. Lithium-ion batteries are ideal for those who value a lightweight and longer runtime, while nickel-cadmium batteries are better suited for those who prioritize durability and performance in extreme conditions.
