60pcs Air/zinc 312 (brown)

10 trays with 312-battery for hearing aids. Has brown sealing tape.

The battery is activated when the tape is taken off. 6 batteries on the tray.

Remember not to touch the part of the battery where the sticker has covered. This can reduce the battery’s capacity and quality.

Allow the battery to air for five minutes after you have removed the sticker on the battery. This will then extend the lifespan significantly according to recent research.
