LITHIUM-ION BATTERY SAFETY & PROTECTION | VOGT CTE

Storage and Transportation

• Store in a cool, dry, dark place: Ideal temperature is 5 – 20 °C, maximum −20 °C to +45 °C. Avoid direct sunlight, frost, or excessive humidity.
• Do not leave in a vehicle where it can overheat (especially during summer or in a closed trunk).
• Avoid mechanical stress: No impacts, crushing, drilling, or bending.
• Transport only in an undamaged condition and using original or approved packaging; secure terminals against short circuits.
• For long-term storage, maintain charge level at approximately 40–60 %.

Charging and Discharging

• Only use original or approved chargers.
• Never leave charging unattended overnight.
• Charge the device on a non-flammable, stable surface (e.g., ceramic tile, metal tray).
• Do not attempt fast charging if the device does not specifically indicate support for it.
• Protect from moisture and dust during charging.
• Avoid discharging below the minimum voltage specified by the manufacturer – deep discharges can shorten lifespan and may cause damage.

Operation

• Maintain allowable ambient temperature (Refer to the relevant data sheet).
• No excessive load: Only connect devices that match the maximum output power.
• Keep ventilation openings unobstructed – overheating may result in fire.
• For portable systems: ensure shock and tilt protection.

Identifying Issues
Immediately turn off and secure if:

• The casing bulges, cracks, or becomes hot,
• Liquid leaks or strange odors occur,
• Heavy smoke or sparks are present.
  Do not use the device and dispose of it safely.

Fire and Emergency Procedures

• In case of smoke or fire: Disconnect the device if it is safe to do so.
• Immediately contact the fire department.
• Suitable for lithium fires: Class D fire extinguisher or copious amounts of water (for cooling, not for extinguishing like grease fires).
• Protect with an appropriate fire blanket certified for Li-ion batteries.
• Ensure the area is ventilated, avoid inhaling toxic fumes.
• Do not rely solely on a blanket or sand – heat accumulation may increase the risk of re-ignition.

Maintenance and Disposal

• Do not open the casing or attempt repairs yourself.
• Regularly inspect for dust, corrosion, and loose cables.
• Dispose of defective or expired batteries only through certified collection points or manufacturer return systems.
• Never throw in household trash.
