The battery
Your mobile is equipped with a high-perf o rmance Li-Ion
b a t t e ry. Optional battery types may be available, check with
your local re t a i l e r. Observe the maintenance guidelines and
your battery should give you a long service life.
• At the beginning of the battery’s life, fully charge and
discharge (let it go flat) three times
• Do not over charge the Li-Ion battery, as this can result
in a reduction in battery performance and life span. The
recommended maximum charge time is 6-8 hours
• Avoid repeated short charging. It is preferable to let the
battery go flat and then recharge it completely
• Avoid charging in strong heat or extreme cold. Ambient
room temperature is preferable. The battery has its
optimum performance in an ambient temperature of
+5 °C to +50 °C
• Don’t store a battery near a fire or heat source
