If your mobile phone battery is damaged, for example if it is dented, we recommend that you stop using it immediately and replace it with a Samsung genuine battery. If a damaged battery is used, this may affect performance of the battery and in some cases cause damage or injury through overheating, fire or explosion.
Examples of situations in which a battery may become damaged are: use in an excessively hot environment, dropping the battery, external pressure on the battery, pet-biting, etc.
Additionally, the phones must have adequate ventilation and airflow and should not be covered with material such as bedding.
We recommend that spare batteries are kept in a hard-shell case when not in use.
You should use only Samsung genuine or approved batteries that have been specifically designed for use in Samsung products. The use of incompatible batteries, cables and chargers may not be safe to use and could cause damage to the device or external damage.
Please purchase Samsung-branded or approved batteries from reputable and approved sellers to ensure the batteries are not counterfeit.For more details, please see Safety information(.pdf).
