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 take two 20V batteries (WORX: snap on a second for 40V tools). The voltage doubles; the amp-hour rating does not.
- 80V tools take four 20V batteries — for example the WG761E 80V self-propelled mower sold on WORX UK.
- No cross-brand compatibility — WORX batteries do not fit Ryobi, Makita, DeWalt, or Milwaukee tools.
- WORX UK sells its chargers for the 20V PowerShare range; charge times vary widely between them (see the charger table).
- PRO batteries (e.g. WA3644 4.0Ah, WA3645 5.0Ah) are higher-capacity PowerShare packs and fit the same tools. We have not found a WORX statement that any tool needs a PRO battery.
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 — mainly mowers and larger chainsaws — two 20V batteries fit the tool at the same time, giving 40V. This keeps the system modular: you use batteries you already own. WORX also sells 80V machines that take four batteries, such as the WG761E self-propelled mower on its UK site.
All Compatible Batteries
WORX sells standard PowerShare packs (e.g. WA3639 2.0Ah) and higher-capacity PRO packs (WA3644 4.0Ah, WA3645 5.0Ah; WA3648 8.0Ah on WORX EU). All are 20V PowerShare batteries. We have not found a WORX statement that PRO tools require PRO batteries.

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 rating: two 5.0Ah batteries give 40V at 5.0Ah, so the stored energy doubles while the amp-hours do not. WORX does not publish runtime comparisons between its 20V and 40V tools.
Which tools use 40V mode?
- WG743 — 40V Lawn Mower (most popular 40V consumer tool)
- WG384E — 40V MAX chainsaw (35 cm bar, two 20V batteries)
- Other 40V garden tools: check the WORX product page for the number of batteries
80V tools take four 20V batteries. For example, WORX UK sells the WG761E 80V 51cm self-propelled mower with four 4.0Ah batteries.
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
WORX UK sells four chargers for the 20V PowerShare range. Charge times differ a lot, so choose by how many batteries you own and how quickly you need them back.
| Charger | Type | Charge time (WORX manual) | Notes |
|---|---|---|---|
| WA3760 | 3-hour slow charger | About 3 hours (WORX name) | WORX UK |
| WA3880 | 1-Hour Fast Charger (2A) | 2.0Ah 58 min; 4.0Ah 125 min; 5.0Ah 145 min | WORX UK; despite the name, over an hour for 2.5Ah and above |
| WA3867 | Ultra-fast charger (6A) | 2.0Ah 25 min; 4.0Ah 45 min; 6.0Ah 70 min | WORX UK |
| WA3883 | Dual-port charger (2A per port) | 2.0Ah 30 min (one); 4.0Ah 1 hr (one), 2 hr (two) | WORX UK manual figures |

Cross-Compatibility Notes
WORX batteries are not interchangeable with Ryobi, Makita, DeWalt, Milwaukee or Bosch batteries. WORX does say PowerShare is used by some other brands that build tools around it, so check for the PowerShare marking on any non-WORX tool.
If you own tools from several brands, you will need separate batteries for each system. Within PowerShare, WORX says one battery system runs all its tools.

Frequently Asked Questions
Are all WORX 20V batteries interchangeable?
Yes. WORX describes PowerShare as one system of stackable 20V batteries used across its tools, so any WORX 20V PowerShare battery — 2.0Ah, 5.0Ah, standard or PRO — fits WORX 20V PowerShare tools. Capacity affects runtime and weight, not fit.
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 packs (for example the WA3644 4.0Ah and WA3645 5.0Ah) are WORX’s higher-capacity PowerShare batteries and fit the same tools as the standard packs. We have not found a WORX statement that any tool needs a PRO battery, so the practical difference is capacity and weight.
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 sells batteries and chargers on its UK website, and they are also listed by UK retailers such as Amazon.co.uk. Check the model number and compare current prices before buying.
Can I use older WORX batteries in newer tools?
WORX describes PowerShare as one 20V battery system across its tools, and its WA3551 page says that battery powers every tool in the PowerShare family. We have not found a WORX statement covering every older 20V or 18V generation, so check the PowerShare marking on both battery and tool.
Summary
WORX PowerShare is a practical system for DIYers and gardeners in the UK: one 20V battery family across WORX’s tools, with 40V and 80V machines that take two or four of the same batteries, and a choice of chargers from a 3-hour slow charger to a 6A ultra-fast model.
