General Recommendations, Safety Guidelines and Precautions concerning the Use of Watch Batteries
Watch batteries are designed and manufactured to meet the special requirements of the watches in which they are used. Serious damage to the watch may result if the wrong battery is used.
When replacing a watch battery, be sure to insert it in accordance with the maker's instructions. Make sure the battery is the right way up, otherwise polarity will be reversed.
When handling a watch battery, do not touch it with your fingers and do not use metal tweezers which will short-circuit the battery. Use only plastic tweezers.
Replace all batteries of a set at the same time. Newly purchased batteries should not be mixed with partially exhausted ones. Batteries of different electrochemical systems, grades or brands should not be mixed. Failure to observe these precautions may result in some batteries in a set being driven beyond their normal exhaustion point and thus increase the possibility of leakage.
Store watch batteries in their original packing in a cool and dry place, at a temperature between 10°C and 20°C. Do not keep batteries in a refrigerator, due to high humidity and the danger of condensation.
Keep batteries out of the reach of children. In case of ingestion of a cell or battery, the person involved should seek medical assistance promptly.
Equipment intended for use by children should have battery compartments which are tamper-proof.
Do not attempt to revive used batteries by heating, charging or other means.
Do not expose batteries to high temperatures, moisture or direct sunlight.
Do not dispose of batteries in fire. Do not dismantle batteries.
Do not short-circuit batteries.
Be sure to comply with your country's legislation regarding the disposal of used batteries.
