• If left unused, a fully charged battery will discharge itself over time. • Use only Samsung-approved batteries, and recharge your battery only with Samsung-approved chargers. Disconnect the charger from the power source when it is not in use. Do not leave the battery connected to a charger for more than a week, since overcharging may shorten its life. • Extreme temperatures will affect the charging capacity of your battery: it may require cooling or warming first. • Do not leave the battery in hot or cold places because the capacity and lifetime of the battery will be reduced. Try to keep the battery at room temperature. A phone with a hot or cold battery may not work temporarily, even when the battery is fully charged. Li-ion batteries are particularly affected by temperatures below 0° C (32° F). • Do not short-circuit the battery. Accidental shortcircuiting can occur when a metallic object like a coin, clip or pen causes a direct connection between the + and - terminals of the battery (metal strips on the battery). For example, do not carry a spare battery in a pocket or bag where the battery may contact metal objects. Short-circuiting the terminals may damage the battery or the object causing the short-circuiting. • Dispose of used batteries in accordance with local regulations. Always recycle. Do not dispose of batteries in a fire. Road safety Your wireless phone gives you the powerful ability to communicate by voice, almost anywhere, anytime. But an important responsibility accompanies the benefits of wireless phones, one that every user must uphold. When you are driving a car, driving is your first responsibility. When using your wireless phone while driving, follow local regulations in the country or region you are in. 43
