Is it safe to mix different batteries
To save money, some people can replace two batteries used in a single device. Is there a right way to extend battery life? The answer is definitely "No".
If two batteries are the same brand, what will happen? The fresh battery provides a large current of almost dead battery with high resistance. Batteries and damage to the device will result in overheating of dead batteries.
Batteries are mixed in different brands, due to the different technologies used they are probably damaged and shortened the service life.
If different types of batteries are used together, excessive explosion and rapid discharge such as technology, material and property discrepancies will lead to unexpected results.
