When you own 2 batteries, you have extra power during time consuming jobs and you do not need to purchase a new battery with every tool you buy.
Once you have purchased 1 battery, you can combine it with any HENX tool body.
Also, batteries last longer if they are used regularly. This means, the more you work with HENX tools, the better it is for the lifecycle of your battery.Landscaping and gardening combined with using our battery technology is definitely more sustainable then using gas-powered equipment.
And not to forget: it is a lot better for the environment too to use battery power instead of gasoline garden tools.
