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

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 lifespan. 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.
