    4.0Ah battery

    Significantly more run time than the 2.0Ah and I can both weedeat and switch to leaf-blower and blow off driveway and sidewalk on the same charge

    Long lasting battery

    Long lasting battery. I used this and seems to be the equivalent of 3 of the regular 2.0 batteries. ( I know that 4.0 is 2x2.0 batteries but seems that it lasted longer).

WORX - 20V Power Share 2.0Ah Battery

You can run your entire Worx Power Share collection of tools on this one 20V 2.0 Ah Max Lithium-Ion Battery. String trimmers and impact drivers, circular saws and lawnmowers, Hydroshots and leaf blowers, the list goes on and on. These batteries are lighter, which makes the tool lighter, and more efficient, than rechargeable batteries based on older designs. Max L-ion batteries don’t wane or drain, and won’t suffer from the memory effect that prevented last generation’s batteries from fully charging as they got older. Plus, they just last longer, so they’ll save you money. You can buy less of them because you can share each one between multiple tools. Cordless tools are much more cost-effective than gas, and you won’t have to worry about getting snagged on a cord. 40V Power Share tools run on this battery too, you just need two of them (20V + 20V = 40V). They provide gas-like power and performance without all the drawbacks of gasoline: no fumes, no mess, no paying at the pump. Depending on the task, and the tool, these batteries will have different runtimes, but a good rule of thumb is that one 20V 2.0 Ah battery will provide enough charge to power our Worx GT String Trimmer/Edger/Mini-Mower through an average 1/4 acre lawn. This battery is compatible with the following chargers (not included): WA3742, WA3868 quick charger, WA3875 dual-port charger, WA3878 quick dual-port charger.

Questions & Answers
  • if i leave it used, why is the battery still self draining?

    Hello there! Thank you for your inquiry. Even when the WA3674 lithium‑ion battery is removed from a tool and not actively being used, a small amount of self‑discharge is normal and expected. Inside the battery are electronic components—such as the protection circuit and battery management system—that continue to draw a very small amount of power to monitor voltage, temperature, and cell safety. This means the battery is never truly “off,” and over time it will slowly lose charge on its own. Factors like cold storage temperatures, how long it’s been sitting since the last charge, and whether it was stored fully charged or nearly empty can make the discharge more noticeable. Storing the battery for long periods fully depleted or fully charged can also accelerate the effect. For best results, WORX recommends storing batteries indoors, at room temperature, and at about a 40–60% charge, which helps minimize self‑drain and extends overall battery life. Thank you for choosing WORX!
