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.

If the performance decrease is greater than 20% in a Lithium-Ion battery,

the battery is at the end of its life cycle. Do not continue to use, and

ensure the battery is disposed of properly.

The length of time that a battery power lasts depends on the battery type and

how the device is used. Conserve the battery life through the following:

 Avoid frequent full discharges because this places additional strain on the

battery. Several partial discharges with frequent recharges are better than

a deep one. Recharging a partially charged lithium-Ion battery does not

cause harm because there is no memory.

 Keep the lithium-Ion battery cool. Avoid a hot car. For prolonged storage,

keep the battery at a 40% charge level.

 Do not leave the lithium-Ion battery discharged and unused for an

extended period because the battery will wear out and the longevity of the

battery will be at least shorter than half of the one with frequent recharges.

Battery charge notice

It is important to consider the environment temperature whenever the

Lithium-Ion battery pack is charged. 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 charging life

cycle.

CAUTION! Do not charge batteries at a temperature lower than 0°C, which will

increase the internal resistance to cause heat and make the

batteries unstable and unsafe. Please use a battery

temperature-detecting device for a charger to ensure a safe

charging temperature range. Further, to protect and avoid battery

from inflating, the battery is detected for thermal protection and will

not be charged when the temperature of battery is over 50

degrees.
