Greenworks G-MAX 40V 5.0Ah Lithium-Ion Battery — Extended Runtime & Fast 120‑Min Charge

Powerful, removable Greenworks G-MAX 40V 5.0Ah battery that delivers fade-free runtime and fast charging for your 40V tools.

Keep your Greenworks 40V tools running at consistent performance with this 5.0Ah lithium-ion pack designed for the G-MAX line. The cell chemistry resists memory loss and self-discharge, so you get reliable starts after storage and consistent power during use. Its snap-in design makes swapping batteries quick, and its zero-emission operation keeps small-engine fumes out of the yard.

How long will this 5.0Ah battery run my tools?

Runtime depends on tool type and workload: lighter tasks like trimming run significantly longer than heavy-duty mowing or blowing. The higher 5.0Ah capacity gives you extended use between charges compared with smaller-capacity packs, reducing interruptions.

• 5.0Ah capacity for extended runtime versus 2–3Ah packs
• Best for moderate sessions on trimmers, blowers, and smaller mowers
• Multiple batteries recommended for continuous heavy use
• Consistent output until the battery nears full depletion

How quickly can I recharge the Greenworks 40V 5.0Ah battery?

The battery reaches a full charge in about 120 minutes when used with the compatible G-MAX charger, making it practical for same-day yard work. Short top-ups between jobs are fast, and the chemistry supports repeated quick-charge cycles without memory effect.

• 120-minute full charge time with model 29482 charger
• Quick top-ups restore usable runtime for short jobs
• No battery memory loss—charge whenever convenient
• Charger sold separately; use only the specified compatible charger

Which tools and chargers work with this Greenworks battery?

This pack is built exclusively for the G-MAX 40V ecosystem. It fits more than 25 Greenworks tools that share the same voltage platform, but it will only operate with the G-MAX 40V charger model 29482 for safe and proper charging.

• Compatible only with Greenworks G-MAX 40V tools
• Use charger model 29482 for correct charging performance
• Ideal as a spare or replacement to expand tool runtime
• Not compatible with non-G-MAX or other-brand batteries/chargers

How durable and low-maintenance is the battery?

The lithium-ion cells are engineered for fade-free power and minimal upkeep. There’s no self-discharge to speak of, so stored batteries remain ready; the snap-in housing protects cells from garden dust and vibration during use.

• No memory effect—charge at any time without damaging capacity
• Low self-discharge keeps batteries ready after storage
• Rugged snap-in design resists impact and simplifies swaps
• Zero fuel emissions—no gas, oil, or tune-ups required

Who is this for? Homeowners and landscapers who already own or plan to build a Greenworks G-MAX 40V toolset will benefit most. Choose this 5.0Ah battery if you want longer runtimes between charges, a reliable spare battery to rotate during larger jobs, or a straightforward upgrade from smaller packs. It’s also a practical choice for anyone prioritizing low maintenance, emissions-free operation, and a single-battery system that powers a wide range of outdoor equipment.
