Cordless garden tool and battery FAQs
Arc-lithium battery FAQs
Can a cordless battery beat petrol for performance?
Yes! Thanks to advances in battery technology, it’s now possible to achieve petrol-matching power — without the noise, fuss or fumes. This makes EGO battery powered cordless equipment not just a viable alternative, but the preferred solution for a wide range of outdoor applications. Discover more about our battery performance.
Are cordless garden tools cheaper to run than petrol alternatives?
Cordless garden tools are much cheaper to run than their petrol counterparts. As an example, over a year, an EGO cordless hedge trimmer will cost only £78 to run. On the other hand, a 2-stroke mix petrol-powered alternative will cost £1,505; and the same tool powered by 2-stroke mix will cost you the grand total of £3,120. (Estimates calculated according to kW pricing in the UK, and the cost of petrol mix based on published UK pricing.) Read more about the cost-savings of cordless garden tools.
Will petrol garden tools be banned in my country?
We hope this happens sooner rather than later. Some US and European cities have already banned certain types of petrol garden tools. This includes Los Angeles, which has banned petrol-powered leaf blowers, and Berlin. To put this into a wider context, the European Commission has committed to banning all petrol cars from city centres by 2050. Many countries, like Denmark, Norway and France, have even more ambitious targets. Change is coming. Discover how you can help speed up better environmental practices.

How is the power of a battery calculated?
Battery power is measured in Watts (W) and calculated using the equation Voltage (V) x Current (A) = Power (W). A big voltage doesn’t necessarily mean big power — there also has to be enough current (and vice versa). With battery powered technology, the current depends on the cell types being used, the condition and quality of the cells, plus the control system that manages them. Capacity can be measured in amp hours (Ah) that are delivered at a given voltage. The length of time power can be delivered by a battery is therefore calculated as Voltage (V) x Capacity (Ah) = Energy (Wh). EGO provides the best balance of voltage and current to deliver the right power and run time for any task — combined with an efficient way of managing and delivering that power for each specific tool.
Are EGO cordless tool batteries better than others?
Yes. Our 56V batteries deliver more usable power than any other hand-held battery - as much as a traditional 80V system. However, an 80V system would not be able to achieve the same usable power as a 56V system because the required battery would be too big and heavy to comfortably use. EGO batteries provide the best balance of voltage and current to deliver the right power and run time for any task — combined with an efficient way of managing and delivering that power for each specific tool. Discover more about our battery performance.
What does the information on a battery label mean?
Each battery should tell you its voltage, amp hours and total power (watt hours). Some battery labels use watts (W) instead of watt hours (Wh). This isn’t as helpful because users don’t just want to know how much power the battery generates in a given moment — they want to know how long it can deliver that power. Watt hours (Wh) is a measurement of energy over time, and an indication of run time. Read more about battery performance.
What does 1P, 2P, 3P, 4P mean?
More battery cells mean more power and run time. Series and parallel circuits can be combined together to pack more punch into a battery. EGO batteries must deliver 56V for an extended period of time. To achieve this, we arrange the right number of cells in series to deliver 56V — then increase capacity (Ah) by adding more cells in parallel.
- 1P means there are enough individual cells to reach 36V, 56V or 80V.
- 2P means there is the same series of cells x2, connected in parallel, to deliver a higher capacity and more power (W).
- 3P means there are the same series of cells x3, connected in parallel, to deliver a higher capacity and more power (W).
- 4P means there are the same series of cells x4, connected in parallel, to deliver a higher capacity and more power (W).

How do we ensure battery cell quality?
Cell consistency is critical to battery performance. All individual battery cells should produce electricity as close to the same characteristics as possible. Inconsistencies could lead to over-charging and discharging, which can impact battery lifecycle and create potential safety issues.
That’s why we only use high quality cells from premium manufacturers. We have excellent relationships with the leading Lithium-ion cell manufacturers and continually assess the market to ensure we source the very best cells in the world.
Even then, we test and select every single cell before building a battery. We test and sort every single cell to ensure we only use the cells with the most consistent voltage. We monitor and manage each cell during operation. The EGO Power+ 56V Arc Lithium battery is continuously controlled by software and microprocessors within the battery and by our tools’ intelligent power management systems.
Discover more about our battery performance.
How do we ensure continuously high battery performance?
Our specially developed Battery Management System constantly monitors and optimises each individual cell, so you always get the very best power, performance and run time. Battery Management System in action Microprocessors and software within the battery, monitor each individual cell for temperature and voltage to ensure that charging and discharging is managed in a balanced and controlled way with the other cells within the pack. This ensures each cell is performing optimally and prolongs the lifetime of the entire battery pack. Discover more about our battery performance.
How does my choice of battery affect power and run time?
The power that batteries generate comes with a trade-off. A battery gets hotter the longer it is used. The more power it generates, the more heat is released. Too much heat and the battery will shut down for safety. Heat also degrades cells over time, reducing battery life. That’s why batteries must be cooled effectively to increase performance run time and battery life. We manage heat while ensuring maximum power, run time and battery lifetime through innovative design. Our unique EGO Power+ 56V Arc Lithium battery maximises cooling in three ways: mechanically, chemically and electronically. Discover more about our battery performance.
How does 56V ARC Lithium battery maximise cooling?
Our unique EGO Power+ 56V Arc Lithium battery maximises cooling in three ways: mechanically, chemically and electronically.
- Mechanical cooling is a design improvement - rather than conventional “brick shaped” batteries where the cells are packed together, overheat and shut down, our unique design maximises surface area and so dissipates heat more effectively.
- Chemically, our batteries actively absorb heat with Keep Cool™ Technology - each and every cell is surrounded by our unique Keep Cool™ phase change material (PCM) that absorbs heat energy and keeps individual cells at their optimum temperature for longer, while increasing battery life.
- Electronically, we individually monitor each cell. Most manufacturers use one or two sensors but this isn’t enough - for example, we engineered 28 sensors to monitor the temperature of all cells (on our 2P battery). The sensors are controlled via the EGO Battery Management System. This ensures safety and prolongs the battery lifetime. Because every cell is monitored, when a specific overheating cell is identified, the entire battery will shut down until it cools down to within the optimum operating parameters.
Discover more about our battery performance.
What is Keep Cool™ Technology?
Keep Cool™ Technology actively absorbs heat naturally generated when the battery is in use. Each and every cell is surrounded by our unique Keep Cool™ phase change material (PCM) that absorbs heat energy and keeps individual cells at their optimum temperature for longer, while increasing battery life. Discover more about our battery performance.
How does Keep Cool™ phase change material work?
When a material goes from a high energy state to a low energy state, it releases energy. For example, liquid water loses energy when it becomes solid ice. And the reverse is true — solid ice gains energy to become liquid water.
When a material is changing state from solid to liquid, the energy applied goes towards changing the state of the material, rather than heating up the battery cell. Our PCM begins absorbing heat as a solid. However, unlike traditional heat storage materials, when the PCM reaches its melting temperature, it absorbs large amounts of energy at an almost constant temperature until all the material is transformed into liquid.
The more heat the PCM absorbs from the battery, the more heat the battery can generate without overheating. This helps to maximise run time. When the battery is not in use, the PCM cools down by safely transferring heat to the atmosphere and turning back into a solid. Discover more about our battery performance.
What’s more powerful: 56v or 80v?
Our 56V batteries deliver more usable power than any other hand-held battery - as much as a traditional 80V system. However, an 80V system would not be able to achieve the same usable power as a 56V system because the required battery would be too big and heavy to comfortably use. Discover more about our battery performance and compare how light our cordless hedge trimmers are.
Should I use a smaller voltage battery for less demanding work?
No. EGO’s range of 56V batteries are designed to deliver the optimum amount of power over the widest range of equipment. The three batteries in our range optimally cover all applications, from leaf blowing to heavy duty cutting. Each battery is 56V. Only the amp hours and weight differ — tailored to provide the right amount of power and run time for each battery’s intended applications. Even the biggest 80V solutions are underpowered at the top range (and overpowered for pretty much everything else).
Similarly, our smaller 56V batteries are perfectly configured to get the job done without sacrificing power — or being lumbered with excess weight. 56V system gives higher flexibility in terms of battery weight and cost, compared to only two options for 80V. For tools that draw power in excess of 3500W an 80V 2P battery will be insufficient too. Discover more about our battery performance.
How do I choose the right battery for the job?
When choosing which battery to use on your EGO tool, there’s really only two things you need to consider:
- How much power do you need for the tool?
- How long the power will last?
From the lightest 2.5Ah to the high density 12.0 Ah battery with the longest run time, we have the right battery for every task. And whatever size you choose, they all feature our innovative 56V Arc Lithium technology. Plus, all our batteries fit all our tools. So whichever you choose, simply click in and get to work.

How fast is an EGO rapid cordless battery charger?
When it’s time to recharge, the EGO Power+ rapid charger is the fastest on the market. The intelligent battery control system constantly monitors each cell’s charge and temperature to deliver the most efficient and quickest charge. Plus, the fan-cooling system allows the battery to start charging sooner and finish faster. As a result, the time it takes to refuel the battery is often less than the run time you get from a full charge. In fact with the rapid charger, the 2.5Ah battery takes just 25 minutes. So with two batteries on the go, you’ll have all the power you need, all day long.
Does use affect battery lifecycle?
Repeated use of the rapid charger can lead to some reduction in cycle life, but this is negligible for the average user. The standard EGO charger (CH2100E) will ensure maximum cycle life due to lower charging currents used. For heavy users, EGO commercial chargers have two charging modes - ensuring the cycle life is protected while providing rapid charging whenever required.
How should I store my Lithium-ion batteries?
Maintaining a full charge over time, without using the battery can damage cells. According to the characteristics of Li-ion cells, when they are stored at full capacity over a long period of time without use, the recoverable capacity will be reduced. EGO batteries discharge automatically after 30 days without use to reach the optimum storage capacity of 30%.
- No special temperature requirements for winter.
- No need to recharge during storage.
- Batteries can be left in the charger.
- Batteries can be used at any state of charge.
- Batteries should be stored dry
How do I transport my Lithium-ion batteries safely?
To keep our batteries safe and sound, the electronics are already protected from dust and moisture by a resin coating and the cells are packaged in a robust case that absorbs shocks and vibrations. However, when transporting batteries, always ensure they are well secured against movement and the terminals are protected from short circuiting. For commercial users, simplified or full ADR (a treaty governing transport of hazardous materials by road) rules apply. For advice, contact your local dealer or EGO directly.
Are EGO batteries weather resistant?
Yes. All EGO batteries are IPX4 rated when connected to the tool. This means they have been proven to be safe for use after splashing with water (equivalent to light rain).
