Greenworks ST80L253 vs 2101602: Choose by Battery Platform and Line Feed

The ST80L253 is the 80V choice with a 16-inch path, .095-inch line and bump feed; the 2101602 is the 40V choice with a 12-inch path, .065-inch dual line and Auto Feed. The Greenworks model pages list each version with a 2.0Ah battery and charger. Verify the current seller bundle, then choose by the Greenworks platform you want and the way you prefer to advance line—not by an unverified promise of faster trimming.

The buying question

Should you choose the ST80L253 80V 16-inch trimmer or the 2101602 40V 12-inch trimmer for your battery platform and preferred line-feed routine?

The ST80L253 uses a 16-inch cutting path, .095-inch line and bump-feed head on Greenworks' 80V platform; the 2101602 uses a 12-inch path, .065-inch dual line and automatic line feed on the 40V platform. The Greenworks model pages list each version with a 2.0Ah battery and charger; verify the current seller bundle before buying.

Quick verdict

When to skip: You need a tool-only package: the manufacturer model pages describe battery-and-charger versions, so verify the seller's exact bundle before buying.
When the recommendation changes
  • An existing Greenworks battery platform can make one option a better fit, but confirm compatibility for your exact tools and battery before relying on sharing.
  • If your priority is real-world trimming speed, runtime, or cut quality, these published specifications do not establish which model performs better.

The differences that matter

Battery Platform And Bundle Fit

Greenworks ST80L253 80V 16-in Cordless String Trimmer (2.0Ah battery listing)

80V Greenworks platform; the product page says the removable battery powers 75+ Greenworks 80V tools. The manufacturer describes this model page as an 80V 2.0Ah battery-and-charger version.[1]

Greenworks 2101602 40V 12-in Cordless String Trimmer (2.0Ah kit)

40V Greenworks platform; the product page says the removable battery powers 75+ Greenworks 40V tools. The manufacturer describes this model page as a 40V 2.0Ah battery-and-charger version.[2]

What this changes: Buyers with existing Greenworks tools can start by matching the platform they own. The manufacturer pages describe separate voltage platforms and battery-and-charger versions; verify the seller's current package and exact tool compatibility if you plan to share a battery.[1, 2]

The better fit depends on your priorities

Line Handling And Cutting Workflow

Greenworks ST80L253 80V 16-in Cordless String Trimmer (2.0Ah battery listing)

16-inch cutting path, maximum .095-inch line and Load N' Go bump-feed head.[1]

Greenworks 2101602 40V 12-in Cordless String Trimmer (2.0Ah kit)

12-inch cutting path, maximum .065-inch line and dual-line Auto Feed head.[2]

What this changes: The ST80L253 is configured for a wider listed path and bump-feed line advancement; the 2101602 uses Auto Feed and a narrower listed path. The feed mechanism changes how the operator advances line, but these specifications do not show which trimmer works faster or cuts better.[1, 2]

Value and trade-offs

One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.

A price difference should be weighed against the battery platform and line-feed setup the buyer actually wants; no price threshold or payback is established here.

There is not enough verified price history to recommend buying now or waiting.

Limitations

  • Greenworks' pages provide published specifications and kit contents, not a matched test of trimming speed, runtime under comparable conditions, cut quality, noise, or yard coverage.
  • Runtime varies with grass conditions and operator technique; this comparison does not use the different published runtime claims to rank the models.
  • The manufacturer model pages describe battery-and-charger versions. Seller bundle options can vary, so confirm the current offer's included components before buying.
  • Confirm compatibility with the exact Greenworks tools and batteries you own before planning to share batteries.

Questions shoppers ask

What do the manufacturer pages list in these bundles?

The Greenworks ST80L253 page lists one 80V 2.0Ah battery and charger, and the 2101602 page lists one 40V 2.0Ah battery and charger. Confirm the seller's current package contents before purchase.

Does either trimmer require bumping the head to advance line?

The ST80L253 uses a bump-feed head. The 2101602 uses Auto Feed, which Greenworks describes as releasing line as the spinning head is activated.
