The Einhell Power X-Change system is a budget-friendly 18V cordless tool platform. Built on a standard 18V lithium-ion pack design, the system offers genuine cross-compatibility across more than 350 tools (Einhell UK) — 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 says all members of the Power X-Change family can be universally combined, so any Einhell PXC 18V battery fits any Einhell PXC tool. The main differences are runtime (capacity in Ah), size and weight (PXC Plus packs use 21700 cells and are up to 13% smaller and 12% lighter) and water resistance (SEALED packs are rated IP57).
Einhell also makes a range of chargers, from the standard 3 A charger to Fastcharger and Boostcharger models. Two 18V batteries can be paired for 36V operation in Twin-Pack tools. Finally, Ozito is the Power X-Change brand sold in Australia and New Zealand; UK retailer Tooled-Up says Einhell and Ozito PXC batteries, chargers and tools are interchangeable.

Battery Selection Guide
Light duty (2–3 hours weekly, drills, small saws): 2.0–2.5 Ah is sufficient. Keeps weight down.
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.
Lighter packs: PXC Plus (3.0 or 4.0 Ah) — up to 13% smaller and 12% lighter than the standard 4.0 Ah (Einhell).
Battery Technology Explained
Standard Lithium-Ion Cells
The standard Power X-Change packs use conventional 18650 lithium-ion cells; Einhell says its standard 4.0 Ah pack has ten of them. They are proven and cost-effective, but larger and heavier than the PXC Plus equivalent.
PLUS Technology (21700 Cells)
The PXC Plus line uses larger 21700 lithium-ion cells. Einhell says five of these give performance comparable to the ten 18650 cells in its standard 4.0 Ah pack, making Plus packs up to 13% smaller and 12% lighter. Einhell does not claim faster charging for Plus packs.
SEALED Technology (IP57 Rating)
SEALED packs (marked with a blue ring) are rated IP57 against water and dust; Einhell says they survive 30 minutes under 1 m of water, and a sensor switches the electronics off on contact with water. Einhell says the rest of the technology is the same as in its Plus batteries. Useful for garden tools and outdoor work in UK weather.
Multi-Ah Intelligent Packs
The Multi-Ah packs switch capacity at the press of a button: 4 or 6 Ah, or 5 or 8 Ah. Einhell says using the lower setting is gentler on the cells and gives up to three times the lifespan, while the higher setting gives up to 60% more runtime (8 Ah against 5 Ah). An LCD shows the charge in percent.
Compatible Tools by Category
Drills & Drivers
Drills are the backbone of the Einhell range. Whether you’re drilling timber, masonry, or driving large fasteners, the Power X-Change system covers every scenario.
| Tool Type | Einhell UK models (examples) | Battery set-up |
|---|---|---|
| Drill/driver | TE-CD 18 series (e.g. TE-CD 18/40 Li BL) | 18 V (one battery) |
| Impact driver | TE-CI 18/1 Li | 18 V (one battery) |
| Angle drill | TE-AD 18 Li | 18 V (one battery) |
Saws (Circular, Jigsaw, Reciprocating)
Saw tools benefit from sustained torque and runtime. Jigsaws are light; chainsaws demand heavier packs.
| Tool Type | Einhell UK models (examples) | Battery set-up |
|---|---|---|
| Circular saw | TE-CS 18/89 Li, TE-CS 18/150 Li, TE-CS 18/165-1 Li | 18 V (one battery) |
| Reciprocating saw | TE-AP 18/13, 18/22, 18/24 and 18/26 Li | 18 V (one battery) |
| Chainsaw | GE-LC 18/25 Li | 18 V (one battery) |
| Chainsaw | GP-LC 36/35 Li | 36 V (two batteries, Twin-Pack) |
Grinders & Rotary Tools
Angle grinders and rotary hammers are demanding tools. Longer-duration packs prevent mid-job battery depletion.
| Tool Type | Einhell UK models (examples) | Battery set-up |
|---|---|---|
| Angle grinder | TE-AG 18/115 Li | 18 V (one battery) |
| Rotary hammer | TE-HD 18/12 Li, TE-HD 18/20 Li | 18 V (one battery) |
| Rotary hammer | HEROCCO 18/20 | 18 V (one battery) |
| Rotary hammer | HEROCCO 36/28 | 36 V (two batteries, Twin-Pack) |
| Multifunction tool | TE-MG 18/1 Li | 18 V (one battery) |
Sanders & Surface Tools
Sanders are lighter on battery demand but benefit from longer runtimes to finish large jobs without interruption.
| Tool Type | Einhell UK models (examples) | Battery set-up |
|---|---|---|
| Random orbital sander | TE-RS 18 Li | 18 V (one battery) |
| Orbital sander | TE-OS 18/113 Li, TE-OS 18/150 Li, TE-OS 18/230 Li | 18 V (one battery) |
Garden Tools (Hedge Trimmers, Chainsaws, Grass Trimmers, Mowers)
Garden tools are a major focus of the Einhell range. SEALED batteries are strongly recommended for outdoor use.
| Tool Type | Einhell UK models (examples) | Battery set-up |
|---|---|---|
| Hedge trimmer | GE-HH 18/45 Li T | 18 V (one battery) |
| Grass trimmer | GE-CT 18 series | 18 V (one battery) |
| Chainsaw | GE-LC 18/25 Li | 18 V (one battery) |
| Lawn mower (18V) | GE-CM 18/30 Li, GE-CM 18/33 Li | 18 V (one battery) |
| Lawn mower (36V) | GE-CM 36 series (e.g. GE-CM 36/37 Li) | 36 V (two batteries, Twin-Pack) |
36V Dual-Battery Mode
Einhell’s Twin-Pack technology lets selected high-power tools — Einhell names lawn mowers, chainsaws and wet/dry vacuum cleaners — run at 36V on two 18V batteries, with up to 2,700 W of output.
In Twin-Pack tools the two 18V batteries are used at the same time, not one after the other. Einhell says any two 18V batteries can be combined, so capacities and technologies do not have to match. Einhell’s Double Twin-Pack tools take four batteries and switch to the second pair when the first two are empty. For maximum runtime, use two higher-capacity packs.
Tools supporting 36V mode include:
- GE-CM 36 lawn mowers (e.g. GE-CM 36/37 Li)
- GP-LC 36/35 Li (chainsaw, two 18V batteries)
- HEROCCO 36/28 rotary hammer
- Double Twin-Pack mowers such as the GE-CM 36/47 HW Li (four batteries)
Charger Compatibility
Einhell offers a range of chargers to suit different needs. All are compatible with all Power X-Change batteries.
| Charger | Slots | Output | Einhell notes |
|---|---|---|---|
| Power X-Charger 3 A (4514095) | 1 | 3 A | Einhell: around 75 minutes for a 4.0 Ah battery |
| Power X-Twincharger 3 A (4512069) | 2 | 3 A per slot | Charges two batteries at once, e.g. for Twin-Pack tools |
| Power X-Quattrocharger 4 A | 4 | 4 A | Charges two at a time, then switches to the other two |
| Power X-Fastcharger 4 A (4512103) | 1 | 4 A | Einhell: a 4.0 Ah battery in about 60 minutes |
| Power X-Boostcharger 6 A | 1 | 3 A; 6 A in boost | Boost for batteries of 2.5 Ah and above |
| Power X-Boostcharger 8 A (4512155) | 1 | 3 A; 8 A in boost | Boost for 5.2 Ah and above; Einhell: charging up to 62% shorter |
| Power X-Car Charger 3 A (4512113) | 1 | 3 A | Runs from a 12 V vehicle socket |
Einhell’s stated charge times are not consistent (one page gives around 75 minutes for a 4.0 Ah on the 3 A charger, another says 2 hours), and its manuals refer you to the charger label, so treat any time as approximate. If you use Twin-Pack 36V tools, a two- or four-slot charger saves waiting.
Cross-Compatibility Notes
Ozito Compatibility
Ozito is the Power X-Change brand sold in Australia and New Zealand (through Bunnings); its website is run by Einhell Australia. UK retailer Tooled-Up states that Power X-Change batteries, chargers and tools are interchangeable between Einhell and Ozito. We have not found an Einhell or Ozito statement confirming cross-brand fit, so check for the PXC marking on both battery and tool before buying.
CAS (Cordless Alliance System) — Einhell Is NOT Part Of It
You may see claims online that Einhell is part of the Cordless Alliance System (CAS). It is not: the CAS brands page lists brands such as Metabo, Mafell, Rothenberger and Starmix, and Einhell does not appear (nor do Makita or DeWalt). Einhell batteries will not work in Makita, DeWalt, Milwaukee, Ryobi, Bosch or other brands’ tools; each system has its own 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 MAX POWER 36V
- 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. Einhell says all members of the Power X-Change family can be universally combined: every PXC battery fits every device in the system, whatever its capacity or technology (standard, PXC Plus, SEALED or Multi-Ah). The differences are runtime, size and weight.
Can I use Einhell batteries in Ozito tools?
According to UK retailer Tooled-Up, yes: Power X-Change batteries, chargers and tools are interchangeable between Einhell and Ozito. Ozito is the Power X-Change brand sold in Australia and New Zealand, and its website is run by Einhell Australia. We have not found an Einhell or Ozito statement on cross-brand fit, so check for the PXC marking on both battery and tool.
Is Einhell part of the Cordless Alliance System (CAS)?
No. Einhell does not appear on the Cordless Alliance System brands page; Power X-Change is Einhell’s own system. Einhell batteries do not fit Makita, DeWalt, Milwaukee or other brands’ tools.
What is the difference between PLUS and SEALED batteries?
PXC Plus batteries use 21700 cells; Einhell says they are up to 13% smaller and 12% lighter than the standard 4.0 Ah pack. SEALED batteries (blue ring) are rated IP57 against water and dust and, Einhell says, otherwise use the same technology as Plus batteries. Einhell does not claim faster charging for either.
Can I use two different capacity batteries in 36V tools?
Yes. Einhell says any two 18 V batteries can be combined in Twin-Pack tools, which use both batteries at the same time. Using two packs of the same capacity is the sensible choice; Einhell does not publish runtimes for mixed pairs.
