Wireless freedom for workshops and gardens

The right battery: Our compatibility promise
Every Power X-Change battery is compatible with all devices in the battery system. The whole range is included, from angle grinders all the way through to vacuums, for your home, workshop, garden or garage. And this also applies to devices yet to be released.

Simply clever: Twin-Pack Technology
18V or 36V? Why not both? With Twin-Pack Technology, one battery type is sufficient for both voltage classes. For more power-intensive applications, such as some lawn mowers, hedge trimmers or hammer drills, simply combine two 18V batteries in one 36V unit.

High quality batteries with charge level indicator
Power X-Change batteries combine first-class technology with practical design. The sturdy, rubberized housing protects against shocks, dust and corrosion. In addition, an LED charge level indicator is integrated into the housing, which provides information about the current battery status.

Short charging time with efficient charger
Optimum battery performance, maximum service life and short charging times? No problem with the Einhell chargers. With the charger, the two 4.0 Ah battery is ready for use after just 75 minutes. If the batterys remains in the charger longer, it is gently charged to 100%.

MADE FOR CHALLENGING WORK
From the processor-controlled Active Battery Management System to the high-quality cells and the cooling-efficient design, all components of the battery have been developed to provide maximum wireless freedom for all projects.

- Reviewed in the United Kingdom on 9 January 2024Style Name: 2 x 4.0AhPattern Name: Without wall bracketVerified PurchaseI recently purchased the Einhell Power X-Change 18V, 4.0Ah Lithium-Ion Battery Twin Charger Starter Kit and I am extremely satisfied with my purchase. This kit comes with 2 high-quality 4.0Ah batteries and a twin charger set that is universally compatible with all Einhell PXC power tools and garden machines.
First of all, I was impressed with how easy it was to set up and use the charger. The instructions were clear and straightforward, and I had both batteries fully charged in just a few hours. The twin charger feature is also very convenient as I can charge both batteries at the same time, saving me time and effort.
The 4.0Ah batteries are a game changer. They have a great battery life and provide long-lasting power for all my power tools and garden machines. I have been using them for a few weeks now and I have yet to run out of power during a project. It's also worth mentioning that these batteries have a quick charge time, so I don't have to wait long before using them again.
I am also impressed with the compatibility of this kit. I own a few Einhell PXC power tools and garden machines and these batteries and charger work perfectly with all of them. This makes it very convenient as I only need to invest in one battery system for all my tools.
The build quality of the batteries and charger is top-notch. They feel durable and sturdy, giving me confidence that they will last a long time. I have dropped them a few times, and they have not sustained any damage. The compact size of the charger also makes it easy to store and carry around.
One thing to note is that this kit is on the pricier side, but in my opinion, it is worth every penny. The quality and convenience it offers make it a great investment for anyone who owns Einhell PXC power tools and garden machines.
In conclusion, the Einhell Power X-Change 18V, 4.0Ah Lithium-Ion Battery Twin Charger Starter Kit is an excellent addition to my tool collection. The quick charge time, long battery life, and compatibility make it a standout product. I highly recommend this kit to anyone looking for a reliable and high-quality battery system for their Einhell PXC tools.
- Reviewed in the United Kingdom on 12 October 2024Style Name: 3.0AhPattern Name: SingleVerified PurchaseBought this battery and charger set to use with a Einhell pole saw I’ve found the batteries last well and charge up fairly quick. I have a few Einhell tools and I find them very good quality and come with decent prices
- Reviewed in the United Kingdom on 21 July 2024Style Name: 3.0AhPattern Name: SingleVerified PurchaseWe have a community garden in the Scottish Highlands and have started to use cordless power tools. Having considered all the options, we opted for the Einhell system. The first purchase was the twin pack of this 3.0Ah battery along with the charger.
The fits thing that was noted was the weight of the batteries. They were heavier than expected but this suggested higher quality. If a battery is very light, it won't last long, as a rule. The construction is very high end and they are so simple to charge and understand. There are clear, well defined lights which indicate the charge levels and I like the button on each battery which you can press to see exactly the amount of charge in any battery. There are also wall mounting recesses on the base, which is a useful touch.
After one charge from new, the batteries were used on the GE-HH 18/45 telescopic hedge cutter. One battery provided 40 minutes of almost continuous use and was then fully charged again in about an hour. That sort of performance, from the mid range power output battery, is very acceptable.
