Which duration correctly describes a BLUE 675 battery?

• A. 1-2 days
• B. 3-4 days
• C. 5-7 days
• D. 2-3 weeks

Answer: (D)

The key idea is that battery life in hearing aids mainly depends on how much energy the battery can store and how quickly the device draws power. The blue 675 is the largest common zinc-air battery size used in hearing aids, so it has the greatest energy capacity among the standard options. With that extra capacity, the hearing aid can run longer on a single battery between changes, typically around two to three weeks under typical daily use. Of course, actual duration varies with things like streaming, listening volume, and how often features that drain power are used, but the larger size means a longer interval before replacement compared to smaller batteries.
