Samsung SGH-D780 manual Precautions when using batteries

Precautions when using batteries

•Never use a charger or battery that is damaged in any way.

•Use the battery only for its intended purpose.

•If you use the phone near the network’s base station, it uses less power. Talk and standby time are greatly affected by the signal strength on the cellular network and the parameters set by the service provider.

•Battery charging time depends on the remaining battery charge, the type of battery, and the charger used. The battery can be charged and discharged hundreds of times, but it will gradually wear out. When the operation 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.

•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).
