Even considering battery and charger purchase costs, savings of £4442 could be made over a five-year period
an operator would use. However, choice of battery depends on the run time required and preferred overall weight - and be recommended by the manufacturer for a particular implement - rather than an integrated battery, so it’s worth considering which tools will be used now and in the future when purchasing batteries. Even backpack batteries are relatively light, and the well-padded, adjustable harnesses were picked out for praise in the test.

On the front of the cabinet is a touch pad that allows the operator to individually control all of the batteries’ charging input and enter petrol and electricity cost data. Standard pre-programmed or maintenance charges can be selected, and the system will calculate the savings made, both in fuel and
