Battery charging time depends on the remaining battery charge and the type of battery and
charger used. The battery can be charged and discharged hundreds of times, but it will
gradually wear out. When the operation time (talk time and standby time) is noticeably
shorter than normal, it is time to buy a new battery.
•
If left unused, a fully charged battery will discharge itself over time and must be recharged
before use.
•
Use only Samsung-approved batteries and recharge your battery only with Samsung-
approved chargers which are specifically designed for your phone. When a charger is not in
use, disconnect it from the power source. Do not leave the battery connected to a charger
for more than a week, since overcharging may shorten its life.
•
Do not use incompatible cell phone batteries and chargers. Some Web sites and second-
hand dealers, not associated with reputable manufacturers and carriers, might be selling
incompatible or even counterfeit batteries and chargers. Consumers should purchase
manufacturer or carrier recommended products and accessories. If unsure about whether a
replacement battery or charger is compatible, contact the manufacturer of the battery or
charger.
•
Misuse or use of incompatible phones, batteries, and charging devices could result in
damage to the equipment and a possible risk of fire, explosion, leakage serious injuries,
damage to your phone, or other serious hazard.
•
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, (below 0 °C (32 °F) or over 45 °C (113 °F)
such as in a car in summer or winter conditions, as you will reduce the charging capacity
and lifetime of the battery. Always try to keep the battery at room temperature. A phone
with a hot or cold battery 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 battery in, on or near areas that may get very hot, such as on or near a
microwave oven, cooking surface, cooking appliance, iron, or radiator. Batteries may
explode when overheated.
