24 x Energizer 675 hearing aid batteries

• The most durable mercury-free Energizer batteries for hearing aids (For high energy consumption).
• Energizer hearing aid batteries with PowerSeal technology protect your devices (against leakage, up to 7 days after complete battery depletion, at room temperature).
• Thanks to the special Energizer EZ Turn & Lock dispenser, batteries can be easily removed whenever needed.
• Longer strips with clearly marked size and color facilitate the purchase and handling of batteries.
• The packaging is 100% recyclable and the batteries contain 0% mercury, which eliminates negative environmental impact.
• The perforated part of the packaging can be torn off, which allows for a reduction in its size. This facilitates transport and storage.

Hearing aid batteries have universal markings by numbers and colors:

• Size 10 / PR70 - always have yellow markings on the blisters and bulk packaging (dimensions: 5.8 x 3.6 mm)
• Size 13 / PR48 - always have orange markings on the blisters and bulk packaging (dimensions: 7.9 x 5.4 mm)
• Size 312 / PR41 - always have brown markings on the blisters and bulk packaging (dimensions: 7.9 x 3.6 mm)
• Size 675 / PR44 - always have blue markings on the blisters and bulk packaging (dimensions: 11.6 x 5.4 mm)

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

• After removing the protective sticker, wait at least about 2 minutes before the battery is activated 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, it is also important to ensure that the battery compartment has the ability for further air penetration.
• 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 or cold ones, e.g., in the refrigerator - this reduces lifespan). Additionally, it is worth remembering to turn off the device at night and when it will not be used for a long time. It is also recommended to leave the battery compartment in the device open at night - this prevents moisture from settling in it, which adversely affects the batteries.
• Avoid: using batteries other than zinc-air (alkaline batteries are significantly weaker and may leak). Avoid keeping discharged batteries in the device or mixing batteries of different brands or mixing new batteries with old ones - always replace the entire set. Do not keep batteries loose together with metal objects.
• What shortens battery life: higher amplification level in the device, turning on additional functions, being in noise, prolonged phone conversation (at the ear), high or low humidity, high or low temperatures, air pollution.
