Battery Notice
1. To guarantee optimal performance, it is recommended that rechargeable
batteries be replaced every year, or after 500 charging cycles are
completed. It is normal for the battery to balloon or expand after one year
or 500 cycles. Although it does not cause damage, it cannot be used again
and must be disposed of according to the location's safe battery disposal
procedures.
2. If a battery performance decreases more than 20%, the battery is at the
end of its life cycle. Stop 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 fully uncharging the battery because this places additional
strain on it. Several partial uncharges with frequent charges are better
than a fully uncharged battery. Charging a partially charged battery
does not cause harm to the unit.
Keep the battery cool. Avoid hot vehicles. For prolonged
storage, keep the battery at a 40% charge level.
Do not leave the battery uncharged and unused for an extended
period of time, the battery will wear out and the longevity of the
battery will be at least half of one with frequent charges.
4. Protect battery life by not over or under charging the battery.
5. Please do not leave battery unused for long time without charging it.
Despite unitech’s safety precautions, the battery pack may begin to
change shape. If so, stop using it immediately. Please check to see if you
are using a proper power adapter to charge the battery or contact your
service provider for service.
6. If you cannot charge the battery after it has been idle for an extended
period of time and it begins to heat up, please do not try to charge it. It
may not be functional anymore.
7. Please only use the original battery from unitech. Using a third party
battery can damage our products. Please note that when such damage
occurs, it is not covered by your warranty.

Battery charge notice
It is important to consider temperature when the battery pack is charging.
Charging is most efficient at normal room temperature or in a slightly cooler
environment. It is essential that batteries are charged within the stated range of
0°C to 40°C. Charging batteries outside of the specified range could damage
the batteries and shorten their life cycle.
CAUTION! Do not charge batteries at a temperature lower than 0°C. This will
and make the batteries unstable and dangerous. Please use a
battery temperature detecting device for a charger to ensure a
safe charging temperature range.
CAUTION! To ensure the unit working properly, please keep all connectors
away from the contaminants staying inside of them such as dust,
grease, mud, and water. The negligence may cause the unit with
no communication, short circuited, overheated and so on.
CAUTION! If the connector is damaged, please ensure the connector is being
fully repaired before use the unit to avoid causing short circuited.
