- Trimming up the garden
- Drilling into timber
- Cracking on with a weekend DIY job
Runtime and reliability are what make or break the task.

As a gardener who uses Worx tools daily, I rely on these batteries every single day — often swapping between two or three to power through longer sessions. Over the seasons, I’ve seen what these batteries can handle and where they start to show wear.

In this hands-on review, we’ll run through what really matters:
- How the Worx 20V lithium battery performs when put to work
- What kind of charge time you’re looking at

My Reviews for the tested products
What Users Say
Plenty of folks report that even after a year or two of regular use, these batteries keep showing up. Of course, if you’re hammering through a full day with high-draw tools, you’ll likely cycle through a couple. But the performance stays steady right through.
The real win? The PowerShare system. Swapping batteries between tools keeps the job flowing without waiting on charge time. That makes the 20V setup a practical, no-faff solution for busy DIYers and gardeners alike.
If you’re after dependable runtime and solid power with no voltage wobbles mid-task, the Worx 20V lithium battery ticks all the right boxes.
Charge Time & Battery Life
One of the first things people want to know is: “How long does it take to charge a Worx 20V lithium battery?” So let’s break it down without the fluff.

Typical Charge Times (Standard Charger)
- 2.0Ah battery: Around 60 minutes
- 4.0Ah battery: Roughly 120 minutes
- 5.0Ah battery: Closer to 130–140 minutes
If you’re in a rush, Worx fast chargers are a game-changer — sometimes cutting charge times nearly in half. That said, heat builds up quickly with fast charging, so it’s worth giving your battery time to cool between rounds.
Battery Life Expectancy
Worx reckons you’ll get about 500 full charge cycles from each battery. In real-world terms:
- Daily users might notice some fade after 1.5–2 years
- Occasional DIYers could see 4–5+ years of steady use
Keep Your Battery Going Longer
- Try not to run it flat — aim to stop around 20%
- Avoid leaving it fully charged or completely drained for long periods
- Store it in a cool, dry place when not in use
All in all, the charge times are nothing out of the ordinary for a 20V system. But when you factor in its long-term reliability and solid performance, the Worx 20V lithium battery earns its place — especially if you keep a couple in rotation to avoid downtime.

Tool Compatibility & PowerShare Benefits
One of the biggest perks of the Worx 20V lithium battery is how much ground it covers. Thanks to the Worx PowerShare system, you can run a whole fleet of tools off just one battery — no faff, no fuss.
What is PowerShare?
PowerShare is Worx’s swappable battery platform that lets you power over 40 different tools with the same 20V battery. That includes everything from garden gear to workshop essentials.

Compatible Tool Types
- Grass trimmers (like the WG163)
- Hedge trimmers
- Leaf blowers (e.g. WG545)
- Drills and impact drivers
- Circular saws
- Sanders and multi-tools
It’s a proper time-saver — fewer batteries to charge, fewer chargers to keep track of, and more flexibility on the job.
Why It Works So Well
- Saves money: No need to shell out for a new battery every time you grab a new tool
- Keeps things moving: Swap batteries on the fly and carry on working
- Tidier setup: Say goodbye to battery clutter in your shed or van
Common Questions
- Can I use a 20V lithium battery on an 18V Worx tool?
Nope — the voltages don’t match, so it’s not compatible. - Will a third-party 20V battery work with Worx tools?
Some do, some don’t. It really depends on the brand. Check reviews first if you’re thinking of going that route.
If you’re building up your kit or already have a few Worx tools in the mix, the Worx 20V lithium battery and PowerShare platform make powering your tools easier, quicker, and a lot less expensive in the long run.
Official vs. Third-Party Battery Comparison
With branded kit creeping up in price, it’s no wonder plenty of folks look to third-party options instead of going straight for the official Worx 20V lithium battery. But when you actually put them to work — how do they stack up?
Side-by-Side Comparison
Feature | Official Worx Battery | Third-Party Battery (e.g., Powerextra, Enelong) |
---|---|---|
Price | £50–£80 | £25–£45 |
Performance | Rock-solid, no fuss | Hit-and-miss — depends on the brand |
Compatibility | Spot-on fit, every time | Might be loose or too snug |
Charge Time | As advertised | Can be slower or less reliable |
Safety Features | Built-in overload protection | Often basic or missing entirely |
Warranty | 1–2 years (depending where you buy) | Usually none, or very limited |
Real-World Testing
For lighter tasks, a lot of third-party batteries hold their own. That said, once you start pushing them with a circular saw or leaf blower, the cracks start to show — literally and figuratively. Some don’t slot in quite right either, and over time that poor fit can lead to dodgy contact or even damage your tool’s terminals.
User Insight
If you’re an occasional DIYer or just trimming up once in a while, a well-reviewed third-party battery could be a decent budget-friendly backup. But if you’re working often or rely on your tools to just get the job done without faff, the official Worx battery gives you that peace of mind.
“Are Worx 20V batteries worth the extra cost?”
If you’re out there grafting regularly — absolutely. If it’s more of a now-and-then thing, a third-party might get you by — just don’t expect it to go the distance.
Most people find the sweet spot is running a mix of both: one official Worx 20V lithium battery to lead the charge, and a third-party spare to fill the gaps when needed.

Longevity & Warranty
When it comes to batteries, it’s not just about power — it’s about how long that power lasts. So, how does the Worx 20V lithium battery hold up in the long run?
Battery Lifespan
Worx rates these batteries for around 500 full charge cycles. With a bit of care, here’s what most users can expect:
- 2–3 years of reliable graft if you’re using your tools on the regular
- 4–5+ years if you’re more of a weekend warrior
Plenty of users say their batteries are still holding strong after several seasons — just with a bit less juice than when they were brand new.
Signs It’s Wearing Out
- You’re getting less runtime than usual
- It takes longer to charge
- It bogs down more easily under load
Battery fade is just part of the deal, but you can slow it down:
- Avoid fully draining it
- Don’t leave it sitting flat for weeks
- Steer clear of hot storage spots — like that sun-baked shed
Warranty Coverage
- Official Worx batteries usually come with a 1–2 year warranty, depending on where you buy
- Third-party batteries are more of a gamble — little to no warranty and limited support if something goes wrong
Verdict
If you’re leaning on your tools regularly, or just want them to work without drama, the official Worx 20V lithium battery is worth the extra spend. But if it’s just for the odd job, a third-party option might tide you over — just be prepared for some trade-offs.
“How many years does a Worx battery last?”
With sensible use and a bit of TLC: 3 to 5 years is a fair shout.
Who Should Buy the Worx 20V Battery?
The Worx 20V lithium battery isn’t just another extra — it’s the backbone of the whole PowerShare setup. So, who’s it really for?
Spot-On For
- Worx PowerShare users: If you’re already running 20V tools, grabbing an extra battery (or two) is a no-brainer.
- Regular DIYers: Builders, handypeople, and anyone who picks up a tool more days than not.
- Gardeners: From hedge trimmers to blowers, the 20V system covers most bases without hassle.
- Anyone building their kit bit by bit: You can start with one battery and grow your tool lineup over time — no need to splash out on a full bundle every time.
Maybe Go Third-Party If
- You only use your gear every now and then — like for seasonal jobs
- You want a cheap spare to get you through a bit more runtime
- You don’t mind slightly shorter life or the odd fit issue
The Smart Setup
Plenty of users find a mix works best — keep one official battery you can trust, and back it up with a third-party spare to cover longer sessions.
Whether you’re deep in weekend DIY or giving the lawn a quick once-over, having the right battery combo makes all the difference. The Worx 20V lithium battery gives you reliability, freedom, and a bit of future-proofing — all in one solid bit of kit.
