The battery can becharged and discharged hundreds of times, but it will graduallywear out. When the operation time (talk time and standby time) isnoticeably shorter than normal, it is time to buy a new battery.♦If left unused, a fully charged battery will discharge itself over time.♦Use only Samsung-approved batteries and recharge your batteryonly with Samsung-approved chargers. When a charger is not inuse, disconnect it from the power source.♦Do not leave the battery connected to a charger for more than aweek, since overcharging may shorten its life.♦Extreme temperatures will affect the charging capacity of yourbattery: it may require cooling or warming first.♦Do not leave the battery in hot or cold places, such as in a car insummer or winter conditions, as you will reduce the capacity andlifetime of the battery. Always try to keep the battery at roomtemperature. A phone with a hot or cold battery may temporarilynot work, even when the battery is fully charged. Li-ion batteriesare particularly affected by temperatures below 0 C (32 F).♦Do not short-circuit the battery. Accidental short-circuiting canoccur when a metallic object (coin, clip or pen) causes a directconnection between the + and terminals of the battery (metal stripson the battery), for example when you carry a spare battery in apocket or bag. Shortcircuiting the terminals may damage thebattery or the object causing the short-circuiting.° °
