BatPower 6.5Ah 20V Battery Replacement Compatible with Worx 20 Volt Lithium-Ion Cordless Tools, High Performance Battery Pack for 20V Nitro Drills, Hydroshot and Leaf Blowers(1 Pack)

What It Is

This is an aftermarket 20V lithium-ion battery replacement for Worx cordless tools, offering a 6.5Ah capacity for longer runtime on trimmers, leaf blowers, drills, and the Hydroshot portable washer.

Fitment & Compatibility

• Voltage & chemistry: Must be 20V lithium-ion (not 40V or NiCad). Works with all Worx 20V Max tools.
• Physical fit: Uses the standard Worx slide-on battery mount—same shape as OEM WA3520/WA3525/WA3530 packs. Fits most Nitro drills, WG629 trimmer, WG520 blower, and WG630 Hydroshot.
• What to check before buying: Remove your old battery and confirm the slide rails are identical. Measure the mounting slot depth (about 1.5 inches) and ensure the terminal slots align. Not compatible with Worx 40V, 12V, or any non-Worx brand tools.
• OEM vs aftermarket: This is a third-party replacement, not Worx OEM. It may lack overcharge protection or temperature sensors found in genuine Worx batteries. Verify your tool’s manual doesn’t void warranty if you use non-OEM batteries.

Key Things to Know

• Installation: Drop-in fit—no tools required. Slide on until it clicks, then press release tab to remove.
• Quality concerns: Capacity is 6.5Ah (vs Worx’s 5.0Ah OEM), but real-world runtime may be 10-20% less due to lower-grade cells. Some users report faster self-discharge after a few months.
• Charger compatibility: Works with any Worx 20V charger (standard or rapid). Do not attempt to charge with 40V or 12V chargers.
• Gotcha: Battery indicator lights (if present) may not be accurate. Fully charge before first use to calibrate.

Should You Buy It

Buy this if you have multiple Worx 20V tools and need a spare battery for light-to-medium yard work (trimming, blowing, drilling) at a lower cost than OEM. Skip if you rely on heavy daily use or need maximum reliability—stick with genuine Worx for better cell quality and warranty support.
