During months of testing across multiple WORX tools in real-world conditions, this battery proved consistently reliable. It weighs approximately 500 grams and fits comfortably in your hand, crucial for overhead and handheld applications where battery weight directly impacts user fatigue. The lithium-ion chemistry eliminates memory effect, letting you charge whenever convenient without damaging battery health.
If you're already invested in WORX tools or building a collection, this battery closes a critical gap: it's more affordable than premium models but outperforms budget alternatives. It's the sensible middle-ground choice for serious weekend warriors.
Score breakdown
Pros
- Remarkably compact and lightweight at ~500 grams, reducing arm fatigue during extended overhead work like hedge trimming or branch cutting
- Rapid charging: reaches full charge in 30-40 minutes with standard WORX chargers, keeping projects moving
- Universal Powershare compatibility with 20V, 40V, and 80V WORX tools maximizes your ecosystem and protects your investment
- Lithium-ion technology delivers fade-free performance—voltage stays consistent throughout discharge, not just at the start
- Zero memory effect: charge at any capacity level without degrading long-term battery health or shortening lifespan
- Exceptional self-storage capability: retains 80-90% charge after months of inactivity, perfect for seasonal tools
Cons
- Runtime limitations on heavy-duty tools—expect 45-60 minutes max on angle grinders or reciprocating saws; longer projects need multiple batteries
- Charger often sold separately depending on package—verify your purchase includes a charger; buying separately adds cost
- No LED fuel gauge or battery percentage indicator; you must rely on tool performance cues to estimate remaining runtime
Verdict
The WORX Powershare Pro 20V 4Ah battery is a genuinely well-engineered backup power solution that earns its place in any WORX tool ecosystem. It strikes an honest balance between affordability and real-world performance, with excellent build quality and broad tool compatibility that keeps your workshop flexible across multiple voltage platforms.
But it's not for everyone. Professional contractors running high-demand tools 8+ hours daily need larger 5Ah or 6Ah capacities. For homeowners, seasonal DIYers, and light commercial users tackling typical weekend projects, this battery delivers solid, worry-free performance at a reasonable price point.

Frequently asked questions
Runtime is tool-dependent. Light work like trimming or leaf blowing delivers 60+ minutes; moderate work like drilling runs 40-50 minutes; heavy-duty applications like angle grinders typically achieve 45-50 minutes before performance noticeably drops. Check your specific tool's manual for precise estimates.
Charger inclusion depends on your bundle. Some packages include it; others sell the battery alone. Always verify the product bundle description before purchasing—buying a charger separately can add significant cost.
It's compatible with WORX 20V, 40V, and 80V Powershare tools manufactured in the last several years. Older WORX models may use proprietary batteries, so check your tool's manual or WORX's compatibility database before assuming compatibility.
Store in a cool, dry place (50-70°F ideally) with roughly 50% charge. Lithium-ion batteries should never be stored completely empty or fully charged. Avoid extreme heat or cold. Under proper storage, expect minimal self-discharge over 3-6 months.
