Nokia Battery Authentication Guidelines - Nokia E73 Guia Del Usuario

Product and safety information
Safe removal. Always switch the device off and disconnect the charger before
removing the battery.
Proper charging. Unplug the charger from the electrical plug and the device when
not in use. Do not leave a fully charged battery connected to a charger, since
overcharging may shorten its lifetime. If left unused, a fully charged battery will
lose its charge over time.
Avoid extreme temperatures. Always try to keep the battery between 59°F and
77°F (15°C and 25°C). Extreme temperatures reduce the capacity and lifetime of
the battery. A device with a hot or cold battery may not work temporarily. Battery
performance is particularly limited in temperatures well below freezing.
Do not short-circuit. Accidental short-circuiting can occur when a metallic object
such as a coin, clip, or pen causes direct connection of the positive (+) and negative
(-) terminals of the battery. (These look like metal strips on the battery.) This might
happen, for example, when you carry a spare battery in your pocket or purse. Short-
circuiting the terminals may damage the battery or the connecting object.
Disposal. Do not dispose of batteries in a fire as they may explode. Dispose of
batteries according to local regulations. Please recycle when possible. Do not
dispose as household waste.
Leak. Do not dismantle, cut, open, crush, bend, puncture, or shred cells or batteries.
In the event of a battery leak, prevent battery liquid contact with skin or eyes. If
this happens, flush the affected areas immediately with water, or seek medical
help.
Damage. Do not modify, remanufacture, attempt to insert foreign objects into the
battery or immerse or expose it to water or other liquids. Batteries may explode
if damaged.
Correct use. Use the battery only for its intended purpose. Improper battery use
may result in a fire, explosion, or other hazard. If the device or battery is dropped,
especially on a hard surface, and you believe the battery has been damaged, take
it to a service center for inspection before continuing to use it. Never use any
charger or battery that is damaged. Keep your battery out of the reach of small
children.
