Battery Charge Notice - Wasp HC1 User Manual

Wasp HC1 User Manual
If the main battery is removed, the backup battery ensures the data on SDRAM is safe for up to 2 hours.
To prevent data loss, do not leave the HC1 uncharged with the main battery removed for an extended
period. See the Charging the Battery unit on for more details.
Note: 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.
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 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 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 half of the one with frequent
recharges.

Battery Charge Notice

It is important to consider the environment temperature when 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. This 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.
