CDMA 450MHz Phone Battery Introduction:

1. A fully charged battery will discharge itself over time if not in use.
2. Extreme temperatures can affect the battery's ability to charge: it may need to be cooled or heated first.
3. Do not put the battery in a place that is too hot or too cold, otherwise, it will reduce the capacity and service life of the battery. Try to keep the battery at room temperature. A phone with a hot or cold battery may not work temporarily, even if the battery is fully charged. Li-ion batteries are especially susceptible to temperatures below 0°C (32°F).
4. Use only approved batteries and chargers. When not using the charger, please disconnect the charger from the power source. Do not leave the battery connected to the charger for more than a week, as overcharging will shorten the battery life.
