Battery Notice

Performance and Replacement

For optimal performance, it is recommended to replace rechargeable batteries annually or after 500 charging cycles.
It’s normal for the battery to swell or expand slightly after a year or 500 cycles. This doesn’t cause damage but indicates the battery should be replaced and disposed of properly according to local regulations.
If battery performance drops by more than 20%, it has reached its end of life and should be replaced and disposed of properly.

Battery Life and Conservation

Battery life depends on the battery type and device usage.
Avoid fully discharging the battery as this puts stress on it. Several partial charges are better than one full discharge.
Do NOT expose the battery or device to high temperatures for extended periods, such as in a parked car on a hot day or under direct sunlight. High temperatures can damage the battery. Keep the device within acceptable operating temperatures (refer to the specifications).
For long-term storage, charge the battery to at least 50% every six months. Leaving the battery uncharged for extended periods will reduce its lifespan.
If the battery cannot be charged after a long idle period and starts to heat up, do not attempt to charge it. It may be damaged.

Important Cautions

Use original batteries only from Unitech. Using third-party batteries can damage the device and void the warranty.
Risk of explosion if the battery is replaced incorrectly. Dispose of used batteries according to instructions.

RISK OF EXPLOSION IF BATTERY IS REPLACED INCORRECTLY.
DISPOSE OF USED BATTERIES ACCORDING TO THE INSTRUCTIONS.

Charging

Consider temperature when charging. Charging is most efficient at room temperature or slightly cooler.

Charge batteries within the specified range of 0°C to 40°C (32°F to 104°F). Charging outside this range can damage the battery and shorten its lifespan.
Do not charge batteries below 0°C. This is dangerous and can make the batteries unstable. Use a battery temperature detecting device to ensure safe charging temperatures.

Maintenance and Safety

Keep all connectors free of contaminants like dust, grease, mud, and water to ensure proper device operation. Neglecting this can cause communication issues, short circuits, or overheating.
To clean the battery connectors:
o Remove the main battery from the mobile computer.
o Dip the cotton part of a cotton-tipped applicator in isopropyl alcohol.
o Gently rub the cotton part of the applicator back and forth across the connectors on both the battery and the device to remove any grease or dirt. Ensure no cotton residue is left on the connectors.
o Repeat this process at least three times.
o Use a dry cotton-tipped applicator and repeat steps 3 and 4.
o Inspect the area for any remaining grease or dirt and repeat the cleaning if needed.
To clean the cradle connectors:
o Disconnect the DC power cable from the cradle.
o Dip the cotton part of a cotton-tipped applicator in isopropyl alcohol.
o Rub the cotton part of the applicator along the pins of the connector, moving it back and forth gently from one side to the other. Do not leave any cotton residue on the connector
o Rub all sides of the connector with the applicator
o Remove any lint left by the applicator
o If there is grease or dirt on other areas of the cradle, use a lint-free cloth and alcohol to clean them
o Allow the alcohol to air dry for at least 10 to 30 minutes (depending on the ambient temperature and humidity) before powering on the cradle

CAUTION! If you clean the battery or cradle connectors with bleach-based chemicals, follow the instructions above to remove any bleach residue from the connectors.

If a connector is damaged, have it repaired before using the device to avoid short circuits.
While charged batteries can be left unused for several months, their capacity may decrease due to internal resistance buildup. They may need recharging before use.

Store batteries at temperatures between -20°C to 60°C. Higher temperatures can cause faster depletion. Room temperature storage is recommended.
The above storage information applies only to removable batteries. For devices with non-removable batteries, refer to the product specifications.

Battery Safety Guidelines

Charge the device in a clean area, away from debris, flammable materials, or chemicals. Take extra care when charging in non-commercial environments.
Improper battery use can lead to fire, explosion, or other hazards.
Do not disassemble, open, crush, bend, deform, puncture, or shred the battery.

Dropping the device can cause the battery to overheat.
Do not short-circuit the battery or allow metal or conductive objects to touch the battery terminals.
Do not modify the battery, insert foreign objects, expose it to water or other liquids, or expose it to fire, explosion, or other hazards.

Do not leave or store the device in hot areas, like parked cars or near heat sources. Do not put the battery in a microwave or dryer.
Supervise battery usage by children.
If swallowed, seek medical advice immediately.

In case of leakage, avoid contact with skin and eyes. If contact occurs, flush the affected area with water for 15 minutes and seek medical advice.
If you suspect damage to the equipment or battery, contact your service provider for inspection.
