WORX PowerShare is one of the UK’s most accessible cordless tool systems, with over 140 compatible tools across power drills, garden machinery, and specialty devices. The beauty of the system is its modular design: a single 20V battery powers compact drills up to 20V chainsaws, while larger chainsaws and mowers use two or four batteries for 40V/80V. This guide covers every compatible battery, tool, and charger, plus how the 40V and 80V dual-battery modes work.
WORX tools are particularly strong in the garden and outdoor space — hedge trimmers, leaf blowers, chainsaws, and mowers dominate WORX’s portfolio. If you’re building a cordless garden kit, WORX offers genuine value compared to premium brands. Availability in the UK is solid: B&Q, Amazon.co.uk, and Screwfix all stock WORX batteries and tools regularly.
Unlike premium brands like Makita or DeWalt, WORX doesn’t offer cross-brand compatibility — their batteries are proprietary. However, the system is genuinely universal within the WORX ecosystem. Buy one battery and charger, and you can use it in any WORX 20V tool you own or buy in the future.
TL;DR Compatibility Rules
- This is an indicative list. WORX model numbers vary by region and generation, so confirm a specific tool on worx.com or simply check that it accepts a 20V PowerShare battery.
- All WORX 20V batteries fit all WORX 20V tools — regardless of capacity or series (standard or PRO).
- 40V tools use two 20V batteries in a shared battery bay. Capacity doubles; runtime roughly doubles.
- 80V tools use four 20V batteries (dual dual-battery mode). Rarely used by DIYers; mostly commercial/professional equipment.
- No cross-brand compatibility — WORX batteries do not fit Ryobi, Makita, DeWalt, or Milwaukee tools.
- Any charger charges any battery — dual-chargers, single chargers, and fast chargers all work with the full battery range.
- PRO vs standard batteries — PRO batteries have slightly higher capacity and power output, but fit the same tools. PRO tools require PRO batteries for full performance; standard tools work fine with both.
How PowerShare Works
WORX PowerShare is built on a simple principle: one battery platform, infinite tools. Every WORX 20V battery has the same connector, so a single 2.0Ah battery works identically in a compact drill and a full-sized chainsaw (though runtimes will vary wildly).
The system scales vertically through battery capacity. A 2.0Ah battery suits light work like small cutting tasks or fastening. A 5.0Ah or 6.0Ah is the sweet spot for most DIYers and regular gardeners — enough runtime for a typical weekend’s work. The 8.0Ah batteries are for contractors and serious users who need extended runtime without battery swaps.
For 40V tools — primarily mowers and larger chainsaws — WORX uses a clever dual-battery cartridge. Two 20V batteries slot into a single tool simultaneously, delivering 40V and roughly double the runtime. This keeps the system modular; you’re not buying entirely new batteries, just using what you already own. A handful of commercial-grade tools use quad-battery (80V) mode, but these are rarely seen on UK consumer sites.
All Compatible Batteries
WORX manufactures batteries in two main families: standard and PRO. Standard batteries are fine for light-to-medium DIY work. PRO batteries deliver higher sustained output and higher capacity (up to 8.0Ah), and they’re required for PRO-tier tools. Chargers are interchangeable across both ranges.
| Battery Model | Capacity | Type | Key Features |
|---|---|---|---|
| WA3575 / WA3669 | 2.0Ah | Standard | Compact, lightweight 2.0Ah packs for light DIY fastening, drilling and cutting. |
| WA3578 | 4.0Ah | Standard (high-capacity) | Higher-capacity standard pack — roughly double the runtime of a 2.0Ah battery. |
| WA3644 / WA3674 | 4.0Ah | PowerShare PRO | Higher sustained output for demanding tools; the WA3644 adds a battery-life indicator. |
| WA3675 | 5.0Ah | PowerShare PRO | Balanced power and runtime for professional-grade tools. |
| WA3678 / WA3648 | 8.0Ah | PowerShare PRO | High-capacity PRO 8.0Ah for extended runtime and all-day use. |

40V and 80V Dual/Quad Battery Mode
WORX’s dual-battery approach is one of its cleverest features. Instead of selling entirely separate 40V batteries, WORX mowers and larger chainsaws accept two standard 20V batteries in a shared bay. This means you’re not forced to buy new batteries — you simply use two of the ones you already own.
When two 20V batteries are used together, the tool receives 40V at the same amp-hour capacity — energy and runtime roughly double, but amp-hours do not. A 5.0Ah + 5.0Ah setup gives 40V at 5.0Ah (runtime roughly doubles because energy doubles, not amp-hours). Runtimes roughly double compared to a single 20V battery, and cutting power increases significantly for demanding tasks like mowing thick lawns or cutting through large logs.
Which tools use 40V mode?
- WG743 — 40V Lawn Mower (most popular 40V consumer tool)
- WG381 — 40V PRO Chainsaw (commercial-grade)
- Select commercial-grade hedge trimmers and multi-tools
80V quad-battery mode is extremely rare in consumer/DIY settings. It’s used by WORX’s larger consumer mowers — for example the Nitro 80V WG761, which runs four 20V batteries in series. These are mainstream consumer machines sold at retail, not industrial-only.
Best practice: For 40V mowers and chainsaws, use two matched batteries of the same capacity (e.g., two 6.0Ah batteries) to ensure balanced power delivery and equal charge wear.
Charger Compatibility
All WORX 20V batteries use the same connector, so any WORX charger charges any WORX battery. Single chargers, dual chargers, fast chargers — they all work identically. Choose based on how many batteries you own and how quickly you need to recharge.
| Charger Model | Type | Charge Time | Best For |
|---|---|---|---|
| WA3742 | Single-bay standard | ~3–5 hours | Lowest-cost option; single-tool owners and casual users. |
| WA3868 | Single-bay quick (20V/18V) | ~60 minutes | Faster single-bay charging. |
| WA3875 | Dual-bay | Charges two packs | Two-battery owners. |
| WA3881 | Dual-bay (fast) | Faster dual charging | Higher battery count; professional users. |

Cross-Compatibility Notes
WORX batteries are proprietary. They do not work in Ryobi, Makita, DeWalt, Milwaukee, or Bosch tools. Similarly, batteries from other brands cannot be used in WORX tools. This is intentional — WORX controls the entire system to ensure safety and performance.
If you own tools from multiple brands, you’ll need separate batteries for each ecosystem. However, within the WORX system, interchangeability is absolute. A battery purchased in 2022 works flawlessly in a tool bought today, and vice versa. WORX maintains backward and forward compatibility better than most premium brands.
Frequently Asked Questions
Are all WORX 20V batteries interchangeable?
Yes, completely. Every WORX 20V battery — whether 2.0Ah, 6.0Ah, standard, or PRO — uses the same connector and fits every WORX 20V tool. Capacity and type (standard vs PRO) affect runtime and power output, not compatibility. Buy a 2.0Ah today and use it in a tool you purchase in three years with no issues.
Can I use WORX batteries in Ryobi or Makita tools?
No. WORX, Ryobi, Makita, DeWalt, and Milwaukee each use proprietary battery connectors. Batteries are not interchangeable across brands. If you own a Ryobi drill and a WORX mower, you’ll need separate batteries for each system.
What is the difference between WORX and WORX PRO batteries?
PRO batteries deliver slightly higher sustained power output and are recommended for professional-grade tools (PRO-tier cordless chisels, advanced circular saws, etc.). Standard tools work fine with both types, but PRO tools perform best with PRO batteries. PRO batteries are also slightly heavier and more expensive. For typical DIY use, standard batteries are sufficient.
How does WORX 40V PowerShare work?
WORX 40V tools accept two 20V batteries simultaneously in a shared battery bay. The tool receives 40V at the same amp-hour rating as a single battery — the voltage doubles while capacity stays the same, so energy and runtime roughly double. For example, two 5.0Ah batteries deliver 40V at 5.0Ah — the amp-hours stay the same, so energy and runtime roughly double. Mowers and larger chainsaws use this approach, letting you reuse existing batteries rather than buying entirely new 40V batteries.
Where can I buy WORX batteries in the UK?
WORX is widely available in the UK. B&Q stocks a full range of batteries and chargers, both in-store and online. Amazon.co.uk has competitive pricing and Prime delivery options. Screwfix also carries WORX products. Prices are generally competitive, and availability is excellent for standard models. Specialty PRO batteries may be harder to find in smaller retailers.
Can I use older WORX batteries in newer tools?
Yes. WORX maintains backward compatibility. A battery from 2015 works in a 2026 tool, and vice versa. The connector standard has remained consistent across generations. However, older batteries may have lower capacity and performance than modern models, so a 2.0Ah battery from ten years ago will still work but deliver shorter runtime than a new 6.0Ah battery.
Summary
WORX PowerShare is a genuinely practical system for DIYers and serious gardeners in the UK. The universal 20V battery platform, solid tool catalogue (especially for garden work), and strong retail availability make it an excellent alternative to premium brands. Whether you’re building a new cordless garden toolkit or expanding an existing WORX collection, any battery you buy will work with any tool you own today or purchase tomorrow. The dual-battery 40V mode adds flexibility without forcing you to buy separate high-capacity batteries, and charger options suit every budget and usage pattern.
