Upgraded 6.0Ah Replacement for Ryobi 40V Battery and Charger Combo Compatible with Ryobi 40V Battery OP4026 OP4026A OP4050 OP4050A OP40601 OP4040 OP4030 OP4015 OP40261 OP40201, with LED Indicator

What It Is

This is a high-capacity 6.0Ah replacement battery for Ryobi 40V cordless lawn mowers, string trimmers, blowers, and other 40V tools. It replaces the standard 4.0Ah or 5.0Ah pack with longer runtime for larger yards or heavy-use tasks.

Fitment & Compatibility

• Models confirmed compatible: OP4026, OP4026A, OP4050, OP4050A, OP40601, OP4040, OP4030, OP4015, OP40261, OP40201 (and most Ryobi 40V tools that use these packs).
• Check before buying: Verify your tool accepts the standard Ryobi 40V slide-on battery form factor. This battery will not fit Ryobi 18V or 36V systems, nor older 40V models with a different connector shape. Measure your existing battery compartment depth—this pack is slightly taller than a 4.0Ah due to extra cells.
• OEM vs aftermarket: This is a third-party replacement, not Ryobi brand. It should charge in any Ryobi 40V charger (OP4040, OP40601, etc.), but performance and lifespan may vary from OEM.
• Physical dimensions: Approximately 5.5 x 3.5 x 4.5 inches; weight ~1.8 lbs.

Key Things to Know

• LED indicator: Four LEDs show approximate charge level when button is pressed. Useful for checking remaining runtime mid-job.
• No installation difficulty: Slides directly onto tool or charger—same as original battery. No tools or adapters needed.
• Runtime: 6.0Ah provides roughly 50% more runtime than a standard 4.0Ah pack. Expect 45–60 minutes in a mower (depending on grass conditions) or 2–3 hours in a trimmer.
• Common gotcha: Some users report the battery may not fit tightly in older Ryobi 40V tools (pre-2018). If your tool has a worn battery latch, the pack might wobble slightly—use a rubber band or tape as a shim if needed.

Should You Buy It

Buy this if you need extra runtime for a large lawn or heavy trimming and already own a Ryobi 40V charger. It’s a cost-effective upgrade over buying a second OEM battery, but skip it if you rely on the warranty or need guaranteed fit in an older tool—stick with Ryobi brand for those cases.
