Key Things to Know

• Capacity vs. OEM: 6.0Ah is higher than standard 4.0Ah packs, giving 50% more run time per charge. However, some users report actual capacity may be slightly lower than advertised.
• Build quality: Aftermarket battery; plastic housing and cell quality may not match OEM durability. Avoid dropping or exposing to extreme temperatures.
• Installation: No tools needed. Slide battery onto tool until it clicks. Remove by pressing the release tab and pulling straight out.
• Warranty & support: Only 4 reviews with 3.6/5 rating—limited user feedback. Return policy may vary by seller. Check seller’s warranty before purchase.

Should You Buy It

Buy this if you need a budget-friendly spare or replacement for your Ryobi 40V tools and are comfortable with aftermarket quality trade-offs. It’s a good choice for light-to-medium use where longer run time is helpful. Skip it if you need maximum reliability for heavy commercial use or want OEM warranty support.
