Battery power vs petrol power

There was a time when it seemed petrol powered outdoor tools would always reign supreme. Battery powered tools were regarded by gardeners as no competition. They couldn’t match the power and uninterrupted operation of their two-stroke counterparts. That time has passed.

Today’s Lithium-ion batteries have revolutionised the way we work with battery powered tools. Now they can produce the power to equal petrol equipment while producing zero emissions at the point of work. Noise levels are also greatly reduced and the benefits don’t stop there.
Vibration is minimised. The lower maintenance costs of battery powered motors lead to substantial long-term savings. Safety is improved by removing the need for fuel filling and on-site storage. There’s no tugging away with recoil starts, with batteries you just charge and go. Instant full power at the push of a button. In many cases one battery will fit a range of tools, interchangeable between a hedgetrimmer, brushcutter, power blower, chainsaw and even a lawn mower.

The traditional argument in favour of petrol and two-stroke, apart from the question of power, was the uninterrupted operation. Batteries quickly ran down and took many hours to recharge. With petrol you just fill up and go. Batteries had a limited life and needed regular, costly replacement. To some extent, operators using outdoor power tools for longer periods of time to get the job completed may argue the need to remain with petrol two-stroke for the time being. But time is running out for fossil fuels, with legislation and health and safety awareness putting the squeeze on the use of petrol power. So it’s good to know there’s an alternative.

Lithium-ion is highly efficient and brings longer battery life, quicker charging times and low self-discharge to the table. The power you need is there instantly, consistently and almost silently.

Battery powered tools do need charging but charge times have become greatly reduced using rapid chargers and most people will have a spare battery on charge in readiness. On the subject of replacement, that is easily weighed up against petrol and two-stroke engines needing regular servicing, with associated costs.

Today’s brushless electric motor is maintenance-free, producing greener, cleaner energy. Emissions are managed by energy efficient motor controls for speed, power delivery and battery temperature, with the added benefits of improved performance and longer battery life. Using a rapid charger, quick charging also reduces downtime so more jobs can be completed in a day; and there is of course the option of using 4Ah batteries for longer run time.

Regular use of handheld petrol-powered tools carries the risk of Hand-arm Vibration (HAV), also known as vibration white finger. This painful condition can be avoided using low vibration tools, which is another benefit of battery powered tools. Other considerations that make battery power a safer option are the fact the user is not working with and storing flammable liquid.

Much reduced noise levels are not only good for the environment in which the work is taking place, the user is not exposed to high noise levels associated with two-stroke petrol powered machinery.

Taking the arguments in favour of battery power, with the benefits to the environment, the user, and those in the vicinity, it’s easy to see why many gardeners are turning to ‘charge and go’. All the power you need with low emissions, low noise, low vibrations, greater safety and reduced costs.

Battery vs petrol? The ultimate choice remains in the hands of the user and what best suits their needs and working environment.
