PENGJBATTER 2 Packs 40 Volt 7500mAh High-Capacity Battery Compatible for Greenworks 40V Battery 29472 29462 2901319 and Greenworks 40V G-MAX Power Tools 2000219, CS40L412, CS40B210, FAN40B00, 22332

What It Is

This is a 40-volt, 7500mAh high-capacity lithium-ion battery pack (2-pack) designed as a replacement for Greenworks 40V G-MAX power tools and select lawn equipment, including string trimmers, blowers, and mowers that accept the standard Greenworks 40V slide-on battery interface.

Fitment & Compatibility

• Compatible with these Greenworks models: 29472, 29462, 2901319, 2000219, CS40L412, CS40B210, FAN40B00, 22332. Also fits any Greenworks 40V G-MAX tool that uses the same slide-on battery mount.
• Not compatible with: Greenworks 60V, 80V, or 24V systems, or any non-G-MAX 40V tools that use a different battery shape (e.g., older push-fit or screw-terminal batteries).
• Before buying: Remove your current battery and check its model number (stamped on the label). Measure the battery slot on your tool—this battery is ~6.5" x 4" x 3.5". If your tool is a Greenworks 40V G-MAX model and the battery slides on/off, it will fit. Does not work with chargers from other brands (use only Greenworks 40V chargers).

Key Things to Know

• Capacity vs. runtime: At 7500mAh, this is a high-capacity option—expect roughly 50-80% more runtime than a standard 2Ah or 4Ah Greenworks battery, depending on your tool’s power draw.
• Aftermarket quality: This is a third-party replacement, not OEM Greenworks. Some users report slightly shorter lifespan or slower charge times compared to genuine Greenworks batteries. The 3.5-star rating reflects mixed durability.
• Installation: No tools needed—just slide onto the battery mount until it clicks. Ensure the contacts align cleanly; if it feels loose, check for debris in the slot.
• Common gotcha: The battery may not fit in all Greenworks 40V chargers if the charger is an older model with a tighter battery slot. Test with your charger before relying on it.

Should You Buy It

Buy this 2-pack if you need extended runtime for heavy yard work (e.g., mulching a large lawn or clearing heavy debris) and you’re comfortable with aftermarket batteries at a lower price than OEM. Skip it if you prioritize long-term reliability or need a battery that matches OEM charging speed—consider a genuine Greenworks 4Ah or 5Ah instead.
