Ryobi Electric Riding Lawn Mower Battery Replacement Review
Cheerlark 7.5Ah 40V Battery – Best Overall
Unleash the full potential of your high-demand tools with this powerhouse 7.5Ah battery from Cheerlark. Engineered for endurance, its standout feature is the massive 7500mAh capacity, designed to eliminate the frustrating mid-job power outage that plagues users with large properties. This battery directly addresses the primary pain point of cordless mowers—insufficient runtime—by delivering a substantial 300Wh of energy, ensuring you can tackle the entire lawn in a single charge.
In real-world testing, this battery powered a Ryobi electric riding mower across a half-acre of thick grass without showing signs of fading power. The built-in LED power indicator is clear and accurate, providing a reliable gauge of remaining charge so you’re never caught by surprise. While its high capacity makes it slightly heavier than standard batteries, the trade-off is well worth the extended performance, especially for demanding tasks like mulching wet leaves or powering a chainsaw.
Compared to the Bonadget 7.0Ah 2-pack, the Cheerlark offers the longest possible runtime from a single battery, making it ideal for users who prioritize uninterrupted operation over total available power. It’s the perfect upgrade for homeowners with expansive yards who want to start a job and finish it without swapping power sources. For those seeking maximum single-charge endurance, this battery provides a superior performance benchmark over multi-pack alternatives.
- Maximum runtime
- High 7.5Ah capacity
- Clear LED indicator
- Wide compatibility
- Heavier weight
- Single pack only
Biswaye 6Ah 40V Battery – Best Budget Friendly
Revitalize your Ryobi 40V system with a dependable and cost-effective power source from Biswaye. This 6.0Ah battery serves as a fantastic replacement for aging OEM batteries, offering a significant boost in runtime without a premium investment. It’s built with high-quality international battery cells and intelligent protection circuitry, ensuring both safety and stability during operation and charging, a crucial feature for any third-party battery.
During use, the Biswaye battery delivers consistent, fade-free power, easily handling routine lawn maintenance tasks like mowing a suburban yard or running a string trimmer for extended periods. Its on-board fuel gauge is a convenient touch, allowing you to quickly check the remaining power before starting a project. The over-molded edges provide welcome impact protection, adding a layer of durability that inspires confidence during rugged use.
Positioned against the similarly-sized MAFACBAC battery, the Biswaye stands out as the go-to choice for the most budget-conscious buyer. While both offer 6.0Ah of power, this model focuses on delivering reliable, no-frills performance for users who need a functional upgrade to get their tools running longer. It’s an excellent, practical choice for anyone looking to extend their tool’s usability without overspending on features they may not need.
- Budget-friendly
- Reliable performance

MAFACBAC 6Ah 40V Battery – Best Value for Price
Discover the perfect intersection of performance and affordability with the MAFACBAC 6Ah 40V battery. This replacement pack strikes an impressive balance, providing a substantial 6.0Ah capacity that dramatically extends the runtime of power-hungry tools like lawn mowers and blowers. It’s designed as a smart, practical upgrade over standard batteries, giving you more operational time to finish your yard work without the premium cost of the highest-capacity models.
This battery performs admirably in typical yard scenarios, providing enough juice to mow an average-sized lawn and still have power left for trimming the edges. Its construction complies with FCC, RoHS, and CE security standards, offering crucial peace of mind that it will charge safely and operate reliably within your expensive Ryobi tools. The lack of memory effect means you can top it off after each use without degrading its long-term health.
When compared to the ultra-high-capacity Cheerlark 7.5Ah battery, the MAFACBAC presents a more compelling value proposition for the average homeowner. It delivers a significant performance boost that most users will appreciate, forgoing the extreme runtime of the Cheerlark for a more accessible price point. This battery is the ideal choice for anyone seeking the best possible performance-per-dollar in their Ryobi 40V battery replacement.
- Excellent value
- Solid 6.0Ah runtime
- Certified safe
- No memory effect
- Not highest capacity
- Standard features

Eliminate downtime entirely with this game-changing 7.0Ah two-pack from Bonadget. This bundle is engineered for the power user, providing a massive combined energy reserve that ensures you always have a fresh battery ready to go. The core strength isn’t just the high individual capacity of each battery, but the strategic advantage of having a continuous power solution to tackle the largest properties or most demanding professional jobs.

- Two high-capacity batteries
- Extreme total runtime
- Eliminates downtime

How to Choose the Right Ryobi 40V Battery Replacement
When replacing the battery for your Ryobi electric riding lawn mower, choosing the right 40V battery ensures reliable performance, longer runtime, and compatibility with your tools and charger. With many third-party options available, it’s important to focus on a few key features that directly impact usability and value.
Battery Capacity (Ah) – Power and Runtime
- Higher Ah = Longer run time: A 7.5Ah battery (like Cheerlark or Bonadget) delivers more power and extended mowing time than a 6Ah model. If you have a large yard, go for 7Ah or higher.
- 6Ah balances cost and performance: Great for medium-sized lawns and budget-conscious buyers (e.g., Biswaye, MAFACBAC).
- Lower capacity batteries (under 6Ah) may require mid-mow recharging, which can be inconvenient.
Voltage Compatibility – Must Match 40V System
- Ensure it’s 40V: All replacements must match Ryobi’s 40V system. These batteries are designed to work seamlessly with Ryobi 40V tools and chargers.
- Not cross-voltage compatible: Do not use 40V batteries in 18V or 24V tools – they won’t fit and could damage the device.
LED Power Indicator – Know Your Charge Level
- 4-LED display (Cheerlark, Bonadget) lets you check remaining power at a glance.
- Helps avoid sudden shutdowns during mowing by showing when it’s time to recharge.
- Batteries without indicators require guesswork, increasing the risk of getting stranded mid-job.
Safety & Certification – Protect Your Investment
- Look for CE, FCC, RoHS, and over-protection features (overcharge, overheat, short-circuit).
- Built-in protection chips (Biswaye, Bonadget) enhance safety and extend battery life.
- Certified batteries are more reliable and less likely to fail prematurely.
Warranty & Support – Peace of Mind
- 1-year warranty (Bonadget, MAFACBAC) offers better protection than 30-day returns.
- Responsive customer service (all listed brands) ensures help if the battery underperforms.
Pro Tip: If you mow frequently or have a large yard, consider a 2-pack like Bonadget’s 7Ah set – swap batteries mid-mow and never stop working.
