The Ewincher battery is made with high quality materials and was tested to ensure optimal operation and maximum battery life. Easy to remove, you can charge it when it's flat or swap it for a spare. These batteries can be taken on an airplane (checked-in and carry-on luggage). This product is sold as a spare/replacement for the Ewincher. 

At the beginning of 2023 the specification of the Ewincher2 battery changed, therefore, when you order a replacement battery we need to get the serial number of your existing Ewincher handle to ensure ship you the correct item. The serial number is written on the label on the Ewincher crank body and composed like this: E01 2021 XX-XX.
