Worx 20V Replacement Battery
High-Capacity Lithium-Ion
Designed for the Worx 20V PowerShare platform, available in two capacity options — 6000mAh (6.0Ah / 120Wh) and 8000mAh — to deliver extended runtime and reliable power for your cordless tools.
Why Choose This Replacement Battery?
Extended Runtime
The 6000mAh version provides at least 2 hours of continuous use on a single charge — compared to roughly 40 minutes with many stock batteries. The 8000mAh option delivers even longer operation, minimizing mid-job battery swaps.
Exceptional Longevity
Rated for up to 1,000 recharge cycles with a low self-discharge rate of approximately 1%, this battery can reliably serve for over 2 years under normal use.
No Memory Effect
Lithium-ion chemistry eliminates memory effect — recharge at any time without reducing capacity or waiting for a full discharge.
Low-Power Standby IC Design
Minimal power drain during storage means the battery stays charged longer when not in use, ready when you need it.
Wide Charger Compatibility
Fully compatible with all standard Worx chargers — no additional adapter required. Just plug in and charge.
Risk-Free Purchase
Backed by a 1-Year Warranty and a 60-Day Money-Back Guarantee with free shipping and 24-hour dispatch.
