DANGER
1. The built-in Lithium-ion Polymer battery is factory replaceable only;
incorrect replacement or tampering with the battery pack may cause
an explosion.
2. Do not use a damaged battery charger.
Do not disassemble or open, crush, bend or deform, puncture or shred.
Do not modify or remanufacture, attempt to insert foreign objects into
the battery, expose to fire, explosion or other hazards.
Make sure to use the charger and USB cables that come together in
the package only. If you use the other charger and USB cables, you
might incur malfunction or failure of the device.
Only use the charging device that has been qualified with device per
the standard. Use of an unqualified battery or charger may present a
risk of fire, explosion, leakage, or other hazards.
Avoid dropping the tester. If the tester is dropped, especially on a hard
surface, and the user suspects damage, contact support.
The battery recharging time varies depending on the remaining battery
capacity.
Battery life inevitably shortens over time.
Since over charging may shorten battery life, remove the tester from its
charger once it is fully charged. Unplug the charger once charging is
complete.
Leaving the tester in hot or cold places, especially inside a car in
summer or winter, may reduce the capacity and life of the battery.
Always keep the battery within normal temperatures.
