The RYOBI 40V 12.0 Ah Battery is a major addition to our RYOBI 40V collection. This 12.0 Ah battery gets 6X more runtime than the RYOBI 40V 2.0 Ah Compact Battery while delivering the same fade-free power and performance. This battery charges in just 120 minutes using RYOBI's 40V Rapid charger. All RYOBI 40 Volt batteries come with an on-board fuel gauge to display remaining runtime. This battery works with select tools in the RYOBI 40-Volt collection, refer to the info and guides section for more information. Backed by a 3-year warranty, there's never been a better time to consider cordless.
