      How to prolong battery life

        To prolong lithium-ion batteries, keep it charged at all times.

        Avoid fully depleting the battery or leaving the battery in a fully discharged state.

        If you only use the Anbooc in the winter season, be sure to put a reminder on your calendar

        to charge the Anbooc every month or two to maintain the battery’s health and ensure it is

        ready to go when cold temperatures return.

      How to prolong heating time

        Factors that affect heating time include the surrounding temperature, humidity, insulation, your hands’ temperature, etc. Heat will escape from the unit faster when in direct contact with the

        cold, thus forcing it to work harder. Hence, it is best to keep the unit insulated in your pocket,

        gloves or scarf.

        If the unit loses heat due to cold hands, keep holding the unit and it will start to feel warm once the amount of heat produced is more than the amount absorbed by your hands.
