Ryobi’s 40 volt (40V) lithium-ion battery platform powers a wide range of outdoor tools and lawn care equipment. This includes trimmers, blowers, chainsaws and of course, cordless electric lawn mowers. The 40V battery lineup provides consistent, sustainable power along with long runtimes per charge making them well-suited for mowing moderate to large yards.
How the 40V Battery System Works
The 40V batteries use lithium-ion cells rather than the 18V cells used in their lower voltage equipment. This allows heavier duty use. While labeled as 40 volts, the batteries actually operate at 36V under a normal workload. Under demanding loads, the voltage peaks around 40V, enabling enhanced power.
All 40V Ryobi tools use the same detachable battery system. Batteries easily slide on and off tools using locking rails. Multiple battery options exist ranging from compact 4Ah units to high capacity 6Ah or even 9Ah batteries for extended cutting. This consistency and cross-compatibility between the mower, chainsaw, trimmer and other tools makes Ryobi’s 40V system highly versatile and cost effective.
40V Battery & Charger Options for the Mowers
Ryobi sells 40V batteries both individually and as bundles with chargers, allowing buyers to customize based on needs:
4Ah Battery – Compact and lightweight at just 2 lbs for easy handling and storage. Provides up to 45 minutes of mowing. Best for smaller yards.
5Ah Battery – At 2.2 lbs, offers light weight along with a full 60 minutes+ of mowing runtime. Combining two 5Ah batteries extends run periods further. Popular general use capacity.
6Ah Battery – Among most popular options with nearly 1.5 hours of mowing but just 2.5 lbs. for easy transport. Cost effective solution for longer runtime.
9Ah Battery – Significantly extended runtime with up to 2 hours of mowing possible per charge. Built ruggedly to withstand heavy commercial use.
Chargers – From compact 40W that recharge small batteries in 30 minutes up to large rapid chargers that power 9Ah units in 60 minutes. Charger speed matches battery capacity.
Choosing higher capacity 6Ah or 9Ah batteries works best for larger lawns to finish mowing on a single charge. Lower capacity 4Ah or 5Ah batteries better fit smaller spaces. Faster, high amp chargers also useful for quickly recharging multiple batteries when mowing bigger yards.
Key Features of the Ryobi 40V Cordless Mowers
Ryobi’s 40V mower system encompasses several models built around brushless motor technology optimized for battery efficiency and power. Shared features fitting home use include:
Durable Brushless Motors
Ryobi brushless motors provide key benefits:
- Maintenance free with longer operating life span than brushed motors
- Run cooler for sustained high power output without wearing down
- More battery runtime per charge through better energy efficiency
The electronically commutated design also allows fast starts for easily resuming when mowing. All translates to enduring, high performance cutting ability from season to season.
Convenient Electric Push Button Start
Starting the mower takes just the press of a button – no pull cords or priming fuel filters as with gasoline mowers. The brushless motor eliminates recoil resistance for an easy, instant start.
Quiet, Emission-Free Operation
With no loud gas motor, the Ryobi cordless mower measured at just 60-65 dB allows quiet daytime mowing. The electric motor also produces no local emissions or unpleasant gas fumes leaving air clean.
Washout Deck Design
The mowers use a rust-proof molded deck with specialized shape that channels, contains and flushes out wet grass clippings. This prevents buildup sticking to deck material while washing away debris through a rear discharge for even cutting while maintaining blade speed.
The deck innovations create sustained, uniform cutting quality even in thicker, wet grass where clumping and staining can hinder performance.
