Product Review

There are plenty of items in Ryobi's tool lineup that run off of 4 Volt batteries. A 4V screwdriver, noise suppressing headphones, the Ryobi inspection scope, and more use these. This is the battery you need to buy to fuel those items. Purchasing this replacement will ensure that you have lots of power at your fingertips. Simply plug this into your 4V Tek4 power tools and enjoy the benefits found in many of Ryobi's lithium ion battery products. For example, you'll get to work with the fade-free power that lets you run your tools at full blast until the battery completely runs out of energy. This is useful for jobs where you'll need consistent results from your tools for a professional-quality look. You will also get to see what life is like with less strain on your joints. This is one of the lightest batteries Ryobi has to offer. With Ryobi's Tek4 line, whether you're driving screws, lighting your workplace, reducing noise on the construction site, or snaking a camera through your car to find a missing fastener, you'll need the AP4001 battery to get your work done right.
