Is this battery worth buying as a spare?

Yes if you already own Greenworks 24V tools and run out of charge mid-job. At $52.99 at Walmart as of November 4, 2026, it costs less than most single-tool batteries and shares every charger on the platform.

Will it fit my Greenworks 24V tools?

It fits any tool on the Greenworks 24V POWERALL platform, including the SVG24L410 and SVW24L410 stick vacuums. It will not fit 40V or 60V Greenworks tools.

How long does it take to charge?

About 48 minutes with a 2-amp Greenworks 24V charger. The charger is not included, so check that you have one for the same voltage platform.

Can I charge my phone with it?

Yes. The pack has a built-in USB-C port, so it works as a portable power bank. Expect it to draw down tool run-time while charging.

One 24V 2.0Ah lithium-ion battery. No charger and no tools are included.

Battery packs usually drop during spring yard-care sales and Black Friday bundles. The current $52.99 at Walmart is already near the bottom of its recent range.
