Ryobi 40V Battery
This Ryobi 40V battery collection covers replacement packs for Ryobi's outdoor power platform — mowers, chainsaws, string trimmers, leaf blowers, and snow blowers. Key facts: 40V packs fit 40V tools only (not the 18V ONE+ system), and popular part numbers include OP4040, OP4050, and OP40601. Every pack uses grade-A cells with full protection circuitry and the original slide connector.

Lawn Mowers
High-capacity packs (OP4050, OP40601 equivalents) for Ryobi walk and riding mowers — expect roughly 20–40 minutes of cutting per 4–6Ah charge depending on deck size and grass load.
Chainsaws & String Trimmers
Balanced-capacity packs (OP4040 equivalents) for chainsaws, trimmers, and hedge cutters — lighter on the arms while keeping steady power under load.
Leaf Blowers & Snow Blowers
Short-burst, high-draw equipment benefits from 5Ah+ packs — higher capacity keeps airflow power consistent from start to finish of the job.
Voltage Warning: 40V ≠ 18V ONE+
Ryobi's 40V outdoor system and its 18V ONE+ system are incompatible — different connectors and chargers. Check the voltage printed on your tool's battery bay before ordering.

Frequently Asked Questions
Can I use a Ryobi 40V battery on 18V tools?
No — 40V and 18V ONE+ are separate platforms with different connectors and chargers. A 40V pack physically will not fit an ONE+ tool bay, and vice versa.
How long does a Ryobi 40V battery last per charge?
Roughly 20–40 minutes on mowers and 25–45 minutes on blowers and trimmers, depending on capacity and load. Lifespan is 2–3 years or 300–500 cycles with proper storage.
What's the difference between OP4040 and OP4050?
Mainly capacity and weight — OP4050-class packs store more energy for mowers and blowers, while OP4040-class packs keep handheld tools lighter. Both fit any 40V tool that accepts slide-in packs.
