Ryobi . P109

Either as a primary or backup battery, these P107s are an excellent addition to any Ryobi user’s arsenal. They are compatible with the One+ tools, letting you power up more than 50 pieces of equipment and counting. These are fade-free batteries. This means that while they have roughly a 1.5 amp hour capacity, they’ll work at full blast until that power runs out. They’re compact, too, which is perfect for smaller tools that you plan on bringing into tight spaces like the multi-tool or drill / driver. They’re also lightweight, which will let you work longer without having your arms tire out. This is important when you’re going for accuracy, where every extra ounce counts. There’s also an onboard fuel gauge, which helps you figure out approximately when you need to charge it. Working in the cold? This has the ability to handle that, too. It can work in temperatures as low as 14 degrees Fahrenheit. As a smaller, more compact version of the P108 lithium ion, the P107 is an excellent choice. Ryobi means work done right.
