Battery Notice
1. To guarantee optimal performance, it is advised that rechargeable
batteries be replaced every year, or when 500 charge/discharge cycles
are achieved. It is normal that the battery balloons or expands beyond
one year or the maximum of 500 cycles. Although it does not cause harm,
it cannot be used again and must be disposed of according to the
location's safe battery disposal procedures.
2. If the performance decrease is greater than 20% in a battery, the battery
is at the end of its life cycle. Do not continue to use, and ensure the
battery is disposed of properly.
3. The length of time that a battery lasts depends on the battery type and
how the device is used. Conserve the battery life by doing the following:
 Avoid frequent full discharges because this places additional strain
on the battery. Several partial discharges with frequent recharges are
better than a full discharge. Recharging a partially charged battery
does not cause harm because there is no memory.

Keep the battery cool. Avoid a hot car. For prolonged
storage, keep the battery at a 40% charge level.
 Do not leave the battery discharged and unused for an extended
period because the battery will wear out and the longevity of the
battery will be at least half of the one with frequent recharges.
4. To keep your battery life time and performance as good, as long as
possible, please do not over charge or over discharge the battery.
5. Please do not leave battery unused for long time without being recharged.
In spite of safety design in the battery pack from unitech, if you may
observe the battery pack being deformed, you should stop using it
immediately. In case of the temperature has met the safety design of

you are using a proper power adapter to recharge the battery or contact
your service provider for service.
6. If you cannot recharge the battery after it has been idle for long time and
you may observe the temperature of the battery is increased abnormally,
please do not attempt to recharge it anymore. You shall stop using it as it
may be over-discharged and not functional anymore.
