Some cameras have specific functionalities in their software that can give us information about the state of the battery. There are also several symptoms that we can identify as unusually short battery life, battery overheating or sudden changes in the percentage of charge. If we suspect that our battery is damaged we can change it for another, if the problem persists it may be a problem with the camera. If we have to buy a new battery it is always better to opt for one of the same brand, be it Olympus, Panasonic, Sony or another. For any questions you can consult our experts at Duke Photography.
