What It Is

The JYJZPB 40V 6.0Ah Lithium-ion Battery is an aftermarket replacement for Greenworks 40V G-Max cordless lawn tools—mowers, trimmers, blowers, chainsaws—that use the original Greenworks 29472, 29462, 29252, and similar batteries. It’s designed to power tools requiring 40V output and a 6.0Ah capacity for longer run time.

Fitment & Compatibility

Check these before buying:

• Works with: Greenworks 40V G-Max tools that accept batteries listed in the title (e.g., 29472, 29462, 29252, 20202, 22262, 25312, 25322, 20642, 22272, 27062, 21242). This includes most recent 40V mowers, trimmers, blowers, and chainsaws.
• Does NOT work with: Greenworks GEN 1 40V batteries (older models with a different shape/connector). If your tool is from before ~2015 or has a square, non-slide battery mount, it’s likely GEN 1.
• Physical check: The battery uses a slide-in mount. Measure your existing battery—this is roughly 5.5” x 3.5” x 5”. If your tool’s battery compartment matches, it should fit.
• OEM vs. aftermarket: This is not a Greenworks-branded battery. It’s a third-party replacement. It will charge on Greenworks 40V chargers (the standard G-Max charger, not GEN 1).

Key Things to Know

• No performance difference for most users: 6.0Ah capacity is higher than the standard 2.0Ah or 4.0Ah packs, so you get longer run time—good for larger yards.
• Installation is plug-and-play: Slide the battery into the tool’s mount until it clicks. No tools or modifications needed.
• Common gotcha: Some users report the battery doesn’t fit snugly in older Greenworks mowers (e.g., 20202). Check that your tool’s battery latch is in good condition—worn latches can cause poor contact.
• Charging note: Works with Greenworks 40V chargers (model 29482, 29492, etc.). If you have a GEN 1 charger, it won’t work.

Should You Buy It

Buy this if you need a reliable, high-capacity replacement for a Greenworks 40V G-Max tool and want to avoid the $80+ OEM price. It’s a solid choice for medium-to-large lawns where longer run time matters. Skip it if you have a GEN 1 tool or need a perfect OEM fit—then stick with Greenworks-branded batteries.
