Battery information The rechargeable battery needs several charge and discharge cycles to reach full capacity! When the operating time becomes noticeably shorter than normal, it is time to buy a new battery. Use only batteries & chargers approved by Binatone and unplug the charger when not in use. (There is a risk of explosion if the lithium battery is replaced by an incorrect type or is not disposed of correctly.) Don't leave the battery connected to a charger for more than 24hr - overcharging may shorten its life. If left unused a charged battery will discharge itself over time. Temperature extremes affect the battery charge - try to keep the battery between 15°C and 25C°. Use the battery only for its intended purpose. Never use a damaged charger or battery. Keep metal objects away from the battery terminals, as short-circuiting them may damage the battery or the connecting object. Dispose of batteries according to local recycling regulations, not as household waste and not in a fire. 28 http://www.binatoneglobal.com
