When I put the batteries in my poket or bag, the batteries get hot. What is the cause?

23 November 2021

If a metal necklace, hairpin, key chain, etc. is included with the battery, if the positive and negative electrodes of the battery are connected by metal for some reason, the battery will short-circuit and the temperature will rise to nearly 100 ° C. When it gets hot, take out the batteries immediately to avoid burns, cool them, put them in a plastic bag, etc., and dispose of them according to the instructions of your municipality.
To prevent short circuits during storage, we recommend that you bring unused batteries without removing the film at the time of purchase, or put them in a small plastic bag and store them alone.
