Modern lithium-ion batteries from Könner & Söhnen® are highly reliable and durable. Their service life is three times longer than lead-acid batteries. They are lightweight and compact, but at the same time, have high battery capacity, and do not require maintenance during the entire lifespan. Additionally, they are equipped with the highest level of protection and feature charge level indication.
FINANCIAL BENEFIT
A significant part of the cost of battery-powered tools is associated with the batteries. The ability to use the same battery for multiple tools ensures significant cost savings. Universal batteries from Könner & Söhnen® are compatible with all battery-powered garden tools of our brand. Therefore, users only need to purchase a battery with the desired capacity and a charging device once, and then use them with any battery-powered tool in our series.
CONVENIENCE DURING WORK
The usage of single battery for multiple tools significantly simplifies the work process, saves time, and reduces work interruptions. There is no need to move, store, or monitor the charge status of various batteries. If you have multiple tasks to be done, simply take one battery with yourself and use it with different tools. Devices without batteries are much lighter in weight, enhancing overall convenience during work.
