The Endurance battery combines the efficiency and eco-friendliness of a rechargeable battery with the low self-discharge and storage capability of a traditional battery. This means that after one year of storage, the battery still retains 85% of its original capacity. As a result, it is always ready for use over an extended period and does not need to be charged first, which extends the battery's lifespan. Thanks to its high performance and fast charging capability, the Endurance also allows for continuous use under the toughest conditions. A significant advantage is its immediate readiness for use after purchase, as the battery is pre-charged and can be used right away. In the long run, the Endurance is not only more cost-effective for you but also benefits the environment.
