Ryobi 18V ONE+™ 4-Pack Compact Batteries Review

4.6 out of 5

The Ryobi 18V ONE+ 4-Pack Compact Batteries have been a staple in my toolkit for quite some time now. As someone who juggles multiple DIY projects and home maintenance tasks, having reliable and versatile batteries is crucial. These compact lithium-ion batteries have proven their worth across a range of tools and applications, making them an essential part of my workshop.

One of the standout features of these batteries is their compatibility with over 70 Ryobi ONE+ tools. This extensive compatibility ensures that I can switch between tools seamlessly without worrying about battery compatibility. Whether I'm using a drill, impact driver, circular saw, or even a leaf blower, these batteries fit perfectly and deliver consistent power.

The 20% more runtime compared to traditional nickel-cadmium batteries is a game-changer. I can tackle larger projects without constantly stopping to recharge. This extended runtime is particularly noticeable with high-draw tools like the reciprocating saw and angle grinder. While there can be a bit of power sag with extremely demanding tools, the performance is generally more than adequate for most tasks. For those really intensive jobs, I do sometimes opt for the 6Ah batteries, but the 4-pack compact batteries handle the majority of my needs efficiently.

Another significant advantage is their lightweight design. These batteries are 45% lighter than the 18-Volt Ni-Cd Battery (P100), which makes a notable difference when working on extended projects. The reduced weight minimizes fatigue, especially when using tools overhead or in awkward positions. This is a boon for anyone who spends long hours on DIY or professional projects.

One minor downside I’ve noticed is the lack of the rubberized edge that older models had. This feature was particularly useful for tools that rest on the battery, providing additional stability and protection. While not a dealbreaker, it’s a small detail that I miss.

Durability-wise, these batteries have held up well over time. I’ve been using them for various projects, from routine home repairs to more demanding woodworking tasks, and they continue to perform reliably. The fade-free power throughout the charge means that I get consistent performance until the battery is fully depleted, which is a crucial factor when working on precision tasks.

Charging these batteries is straightforward with the standard Ryobi chargers. They charge relatively quickly and the charge indicators are a helpful feature, allowing me to see at a glance how much power is left. This is particularly useful when planning my work and ensuring I have enough charged batteries ready to go.

I've had a few instances where the batteries stopped taking a charge, but Ryobi's customer service has been exceptional. Their prompt response and hassle-free replacement process have reinforced my confidence in the brand. It’s worth noting, however, that registering your products on the Ryobi website can streamline this process and is highly recommended.

For those who prefer a lighter tool for ease of handling, the 2.0Ah batteries in this pack are a great option. They provide a good balance between power and weight, making them ideal for less demanding tasks or for users who need a lighter tool for extended periods. While they don’t last as long as the 4.0Ah batteries, they are sufficient for many everyday tasks and are easier on the arms.

In terms of performance, these batteries deliver ample power for a wide range of tasks. From cutting through tough materials with the circular saw to driving screws with the drill, the power output is consistent and reliable. Even for high-demand tools like the chainsaw, these batteries provide enough juice to get the job done, although for more intensive tasks, having a couple of fully charged spares is advisable.

One aspect that could be improved is the ease of removing the batteries from the charger and tools. The latches can be a bit stiff and require some effort to release. Over time, this has become less of an issue as the batteries have worn in, but it’s something to be aware of, especially for users with limited hand strength.

Overall, the Ryobi 18V ONE+ 4-Pack Compact Batteries have proven to be a valuable addition to my tool collection. They offer a great blend of power, runtime, and lightweight design, making them suitable for a variety of tasks. The extensive compatibility with Ryobi tools and the excellent customer service further enhance their appeal.

I would highly recommend these batteries to both DIY enthusiasts and professionals alike. Their performance, durability, and ease of use make them a reliable choice for anyone looking to power their Ryobi ONE+ tools. Whether you’re working on home improvement projects, woodworking, or just need a dependable power source for your tools, these batteries are a solid investment.
