WARNING
1. Use only 3.6V lithium batteries, model 18650B with PCB-protection (button top).
2. Submit a repair request immediately in case of battery leakage, discoloration,
deformation or abnormal condition.
3. Clean immediately with tap water if your skin or clothing comes into contact with
a leaking battery.
4. Keep the battery charger free of any covering during charging.
5. Do not charge the batteries in the vicinity of ammable gas or materials.
ATTENTION
1. Do not use or store the batteries or borescope in a high-temperature environment,
such as direct sunlight, closed cars or near heating equipment.
2. e batteries will heat up during prolonged operation. Do not remove immediately
aer use, as this could cause burns.
3. Keep batteries and borescope out of the reach of children.
4. Do not touch the battery electrodes with wet hands.
5. Fully charge the batteries before use and aer extended use.
6. Remove the batteries from the borescope if the scope will not be used for more than
30 days, otherwise, it may cause damage to the borescope, re or personal injury.
REMINDER
1. ese are high-output batteries. Please use the batteries properly or it may cause
damage from leakage or excessive heat. Always check the orientation / polarity and
load batteries into the chamber correctly.
2. Batteries performance will decrease as the ambient temperature drops.
Performance will be restored once the ambient temperature rises.
3. Recycle the batteries in accordance with local regulations at the end of their
useful life.
4. Recommended temperature range for this lithium ion battery is:
• Discharging (in use): 0°C to 40°C (32°F to 104°F)
• Charging: 0°C to 40°C (32°F to 104°F)
• Storage: -10°C to 40°C (14° to 104°F)
5. Using, charging or storing the batteries at a temperature out of the above range will
reduce the battery performance and service life.
6. Be sure to remove the batteries from the borescope for long term storage.
