given to this apparatus and might be dangerous.
Warning! When you purchase batteries, chargers, and accessories for your
phone, use only batteries, chargers, and accessories that have received

When the battery is fully charged, the indicator will tell you that the
battery is fully charged.
•
When you are not using a charger, disconnect it from the power source.
Do not leave the battery connected to a charger for more than a week,
since overcharging could shorten its life span. If left unused, a fully
charged battery will discharge itself over time.
Temperature extremes can affect the ability of your battery to charge.
Therefore, allow it to cool down or warm up before trying to charge it.
