The Einhell Power X-Change system is one of the most popular budget-friendly 18V cordless tool platforms in the UK. Built on a standard 18V lithium-ion pack design, the system offers genuine cross-compatibility across more than 300 tools — from basic drills to professional-grade chainsaws, angle grinders, and rotary hammers. Whether you’re a tradesperson running a full workshop or a DIYer tackling weekend jobs, understanding which batteries work with which tools is essential for getting the right runtime and performance without unnecessary spending.
This guide covers every Einhell Power X-Change battery, every compatible tool by category, the role of the PLUS and SEALED battery lines, and how the dual-battery 36V mode works. We’ll also explain why Ozito compatibility is real, why Einhell is often misrepresented as part of the CAS (Cordless Alliance System), and how to avoid wasting money on incompatible equipment.
TL;DR Compatibility Rules
Before diving into the detail: Einhell Power X-Change batteries are 100% cross-compatible across all tools within the 18V range. Any Einhell 18V battery fits any Einhell 18V tool — there are no voltage or connector variants to worry about. The main differences are runtime (determined by capacity in Ah) and features (PLUS batteries use faster-charging 21700 cells; SEALED batteries are IP57-rated for wet work).
Einhell also makes compatible chargers ranging from standard to fast-charge and boost modes. Two 18V batteries can be paired for 36V operation in specific larger tools. Finally, Ozito tools are 100% compatible with Einhell batteries — Ozito is Einhell’s UK budget sub-brand and uses the identical connector and voltage.

Regular use (5–10 hours weekly, mixed tools): 4.0 Ah standard is the sweet spot. Good runtime without excessive weight.
Heavy/continuous use (10+ hours, rotary hammers, grinders, chainsaws): 5.2 Ah or Multi-Ah packs. Reduced battery swaps, sustained power.
Wet environment work (garden tools, exterior): SEALED (IP57) 4.0 Ah. Waterproof rating protects against rain and direct spray.
Fast charging priority: PLUS variants (3.0 or 4.0). Ready in 20–25 minutes.
Battery Technology Explained
Standard Lithium-Ion Cells
The base Power X-Change range uses conventional 18650 lithium-ion cells. These are proven, reliable, and cost-effective. Charge times are longer (30–65 minutes depending on capacity), and the packs are slightly heavier for the same capacity compared to PLUS versions. These batteries are recommended for workshops with standard chargers and users who don’t mind waiting between battery swaps.
PLUS Technology (21700 Cells)
The PLUS line uses larger 21700 lithium-ion cells, allowing for faster charge times without reducing battery lifespan. A 4.0 Ah PLUS battery charges in roughly 25 minutes versus 50 minutes for standard. PLUS packs are slightly more expensive but ideal if you’re juggling multiple tools or need quick turnaround. They’re physically similar in weight and size to standard equivalents but pack denser energy.
SEALED Technology (IP57 Rating)
The SEALED variant adds an IP57 waterproof rating, meaning the pack can withstand temporary submersion and heavy spray. Designed for garden tools (chainsaws, hedge trimmers, grass trimmers) and exterior work. Charge time is standard; the waterproofing adds minimal weight. Highly recommended if you use cordless tools outdoors in UK weather.
Multi-Ah Intelligent Packs
The 4–6 Ah and 5–8 Ah Multi-Ah packs feature a smart electronic control that adjusts discharge rate based on tool demand. Light tools receive lower current, extending runtime; heavy tools get full current for peak performance. This flexibility reduces the need to carry multiple capacity packs. They’re an investment but suit professionals managing diverse workloads.

36V Dual-Battery Mode
Einhell’s larger garden and workshop tools support 36V operation using two 18V batteries. This effectively doubles voltage, increasing torque and power for demanding applications like heavy lawn mowers, scarifiers, and chainsaws.
In 36V mode, two 18V batteries are mounted side-by-side on a shared holder. Any two Power X-Change 18V batteries can be used — they don’t need to match capacity or technology (e.g., you can pair a 4.0 Ah standard with a 4.0 Ah PLUS). The system will use both batteries sequentially until both are depleted. For maximum runtime, use two higher-capacity packs (5.2 Ah or 4–6 Ah Multi-Ah).
Tools supporting 36V mode include:
- GE-CM 18 (Lawn Mower)
- GE-LC 36/40 (Heavy Chainsaw)
- GE-SC 18 (Scarifier, with 36V bracket)
- Various contractor-grade rotary hammers and heavy grinders
Charger Compatibility
Einhell offers a range of chargers to suit different needs. All are compatible with all Power X-Change batteries.
| Charger Model | Type | Input | Charge Time (4.0 Ah) | Best For |
|---|---|---|---|---|
| TC-LC 18 | Standard Single-Slot | 230V AC | ~50 mins | Home workshop, occasional use. |
| TC-LC FAST | Fast-Charge Single-Slot | 230V AC | ~25 mins | Quick turnaround, frequent battery swaps. |
| TC-LC BOOST | Boost/Ultra-Fast Single-Slot | 230V AC | ~15 mins | Professional use, minimal downtime. |
| TC-LC DUAL | Dual-Slot Standard | 230V AC | ~50 mins per pack | Two batteries charged simultaneously. Workshop favourite. |
| TC-LC SMART | Smart Multi-Slot | 230V AC | Variable | Intelligent diagnostics. Charges up to 4 batteries with adaptive timing. |
Recommendation: If you own two or more Power X-Change tools, invest in at least a TC-LC DUAL charger. It eliminates downtime by charging two batteries simultaneously. If you use heavy tools regularly (grinders, impact drivers), the TC-LC FAST is a worthwhile upgrade over standard.
Cross-Compatibility Notes
Ozito Compatibility (100% Real)
Ozito is Einhell’s UK budget sub-brand, sold through Bunnings and online retailers. Ozito Power X-Change tools and batteries are 100% identical to Einhell equivalents — same connector, same voltage, same capacity ratings. An Einhell 4.0 Ah battery fits seamlessly into an Ozito drill, and vice versa. If you already own Ozito tools, you can upgrade to Einhell batteries (often cheaper in bulk) without any hesitation.
CAS (Cordless Alliance System) — Einhell Is NOT Part Of It
You may see online claims that Einhell is part of the CAS (Cordless Alliance System), a coalition supposedly linking Makita, DeWalt, and other brands. This is incorrect. Einhell is not a CAS member. Einhell batteries will not work in Makita, DeWalt, Milwaukee, Ryobi, Bosch, or any other brand’s tools. Each system has a proprietary connector.
The confusion likely stems from casual remarks online or misunderstandings about industrial standards. For clarity: Einhell and Ozito stand alone. Compatibility is confined to the Power X-Change ecosystem.
No Cross-Brand Compatibility
Einhell Power X-Change batteries are incompatible with:
- Makita 18V LXT, XGT, or G-Series
- DeWalt 20V MAX or FLEXVOLT
- Milwaukee M18 or M12
- Ryobi ONE+ or ZRRY40250
- Bosch 18V or AMPShare
- Festool, Metabo, Hitachi, or any other third-party brand
Invest in batteries that match your tool platform. Mixing platforms leads to expensive mistakes.
Frequently Asked Questions
Are all Einhell Power X-Change batteries interchangeable?
Yes, completely. Every Einhell 18V battery — regardless of capacity (2.0 Ah to 5.2 Ah), technology (standard, PLUS, SEALED, or Multi-Ah) — fits every Einhell 18V tool. There are no variant connectors or voltage mismatches. The only difference is runtime and charge time. You can confidently move batteries between tools without worrying about damage or incompatibility.
Can I use Einhell batteries in Ozito tools?
Yes. Ozito is Einhell’s own budget brand, and the products are electrically and mechanically identical. An Einhell 4.0 Ah battery works in an Ozito drill, and vice versa. This also means Ozito batteries work in Einhell tools. They’re one ecosystem sold under two labels.
Is Einhell part of the Cordless Alliance System (CAS)?
No. Einhell is not a CAS member and never has been. The CAS is primarily a European industrial standard involving other manufacturers, but Einhell operates its own proprietary system. Einhell batteries will not work in Makita, DeWalt, Milwaukee, or any other brand. Einhell tools are an independent ecosystem.
What is the difference between PLUS and SEALED batteries?
PLUS batteries use larger 21700 lithium-ion cells, allowing for significantly faster charging (20–25 minutes versus 50+ minutes). They cost slightly more but are ideal if you regularly swap batteries or need quick turnaround. SEALED batteries have an IP57 waterproof rating, making them suitable for outdoor work, garden tools, and wet conditions. A SEALED battery may charge at standard speed but protects against rain and spray. For professional outdoor use, SEALED is worth the investment.
Can I use two different capacity batteries in 36V tools?
Yes. In 36V mode (two 18V packs side-by-side), you can mix capacities — for example, a 4.0 Ah and a 5.2 Ah together. The system uses both batteries sequentially until both are empty. However, for optimal runtime balance, it’s better to use two packs of the same capacity. If you must mix, the lower-capacity battery will deplete first, and the tool will draw from the second until that too is exhausted.
