longer-lasting power over manufacturers which have their batteries encased within their tools. From a chemical perspective, each battery cell (up to and including the 5.0Ah battery) is surrounded by a unique phase change material (PCM) that absorbs energy and keeps individual cells at their optimum temperature for longer. The more heat the PCM absorbs from the battery, the more heat the battery can generate without overheating, helping to maximise run time. Electronically, many manufacturers of battery-powered tools will use one or two sensors to monitor the battery’s temperature. Typically, these are located on the cells that are most likely to become the hottest and some have even been known to locate them by the coolest cells. EGO recognises that cells can change after several charge cycles, meaning that these sensors can become ineffective by no longer monitoring the hottest cells.
To counter this, there are engineered sensors to monitor the temperature of all the individual battery’s cells. By doing so, in the event of a cell reaching a high temperature, the entire battery will shut down until it cools down to within the optimum operating parameters. This not only ensures safe use but also extended battery life.
How should batteries be stored?
Contrary to popular belief, the batteries don’t require special temperature requirements for winter storage. All that is advised is that batteries aren’t

over time, reducing battery life. That’s why batteries must be cooled effectively to increase performance run time and battery life
stored in direct sunlight or in a place where they can attract moisture.
The cost of evolution
Now that you have a basic understanding of battery technology and its role in the outdoor power tool market, you will probably have one more burning question; cost. Upfront costs for the technology can be higher than that of your average petrol-powered tool. However, research investigated the total cost of ownership between petrol and battery-powered outdoor equipment over an extended period. The test looked at the cost of a petrol brush cutter, hedge trimmer and leaf blower compared with their battery-powered counterparts. Initially, buyers would spend approximately £690 extra on battery- powered equipment in year one, however
would see a turnaround in just their second year of ownership, making a total saving of £365. In years three and four, the real savings of ditching petrol begin to show themselves, with users saving a total of £1,430 and £3,500 respectively. By the fifth year, the test factored in a full replacement of all equipment and yet the savings amounted to a total lifetime saving of over £4,500! This is in large part due to the inexpensive cost of recharging a battery (typically well under 10 pence for a full recharge) compared to the cost of petrol, and also the lack of servicing required for battery powered tools.
