How to fully appreciate the advantages of zinc-air technology?

• After removing the protective sticker, wait at least approx. 2 minutes before the battery is started in the device. This time is needed for oxygen to penetrate the battery structures - only then does the battery activate and reach the appropriate voltage for operation. During battery operation, care must also be taken to ensure that the battery compartment is able to penetrate the air further.
• Batteries will last longer if they come from fresh production (long shelf life) and are stored in a dry and cool place (avoid storing batteries in hot places and cold places, e.g. in the refrigerator - this reduces the lifespan). In addition, it is worth remembering to turn off the camera at night and when it is to be unused for a long time. It is also recommended to leave the battery compartment in the camera open at night - this will prevent moisture from settling in it, which has a bad effect on the batteries.
• Beware: use of batteries other than zinc-air batteries (alkaline batteries are much weaker and may spill). Avoid keeping dead batteries in the camera or mixing batteries of different brands or new batteries with old ones - always replace the entire set. Also, do not keep the battery loose together with metal objects.
• What shortens battery life: higher level of gain in the camera, inclusion of additional functions, being in noise, prolonged talking on the phone (by the ear), high humidity, high or low temperatures, air pollution.
