Section 13: Health and Safety Information 150• Follow battery usage, storage and charging guidelines found in the user’sguide.• Battery charging time depends on the remaining battery charge and the type ofbattery and charger used. The battery can be charged and dischargedhundreds of times, but it will gradually wear out. When the operation time (talktime and idle time) is noticeably shorter than normal, it is time to buy a newbattery.• If left unused, a fully charged battery will discharge itself over time.• Use only Samsung-approved batteries and recharge your battery only withSamsung-approved chargers. When a charger is not in use, disconnect it fromthe power source. Do not leave the battery connected to a charger for morethan a week, since overcharging may shorten its life.• Do not use incompatible cell phone batteries and chargers. Some Web sitesand second-hand dealers, not associated with reputable manufacturers andcarriers, might be selling incompatible or even counterfeit batteries andchargers. Consumers should purchase manufacturer or carrier recommendedproducts and accessories. If unsure about whether a replacement battery orcharger is compatible, contact the manufacturer of the battery or charger.• Extreme temperatures will affect the charging capacity of your battery: it mayrequire cooling or warming first.• Do not leave the battery in hot or cold places, such as in a car in summer orwinter conditions, as you will reduce the capacity and lifetime of the battery.Always try to keep the battery at room temperature. A phone with a hot or coldbattery may temporarily not work, even when the battery is fully charged. Li-ion batteries are particularly affected by temperatures below 0 °C (32 °F).• Do not place the phone in areas that may get very hot, such as on or near acooking surface, cooking appliance, iron, or radiator.• Do not get your phone or battery wet. Even though they will dry and appear tooperate normally, the circuitry could slowly corrode and pose a safety hazard.• Do not short-circuit the battery. Accidental short- circuiting can occur when ametallic object (coin, clip or pen) causes a direct connection between the +and - terminals of the battery (metal strips on the battery), for example whenyou carry a spare battery in a pocket or bag. Short-circuiting the terminalsmay damage the battery or the object causing the short-circuiting.• Do not permit a battery out of the phone to come in contact with metal objects,such as coins, keys or jewelry.• Do not crush, puncture or put a high degree of pressure on the battery as thiscan cause an internal short-circuit, resulting in overheating.• Dispose of used batteries in accordance with local regulations. In some areas,the disposal of batteries in household or business trash may be prohibited.For safe disposal options for Li-Ion batteries, contact your nearest Samsungauthorized service center.
