Battery information

Charging and discharging
Your game deck is powered by a rechargeable battery. The full performance of a new
battery is achieved only after two or three complete charge and discharge cycles. The
battery can be charged and discharged hundreds of times but it will eventually wear
out. When the talk and standby times are noticeably shorter than normal, buy a new
battery. Use only Nokia approved batteries, and recharge your battery only with Nokia
approved chargers designated for this game deck.
Unplug the charger from the electrical plug and the game deck when not in use. Do not
leave the battery connected to a charger. Overcharging may shorten its lifetime. If left
unused, a fully charged battery will lose its charge over time. Temperature extremes can
affect the ability of your battery to charge.
Use the battery only for its intended purpose. Never use any charger or battery that is
damaged.
Do not short-circuit the battery. 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.
Leaving the battery in hot or cold places, such as in a closed car in summer or winter
conditions, will reduce the capacity and lifetime of the battery. Always try to keep the
battery between 59°F and 77°F (15°C and 25°C). A game deck with a hot or cold battery
may not work temporarily, even when the battery is fully charged. Battery performance
is particularly limited in temperatures well below freezing.
