Renata Maratone+ Size 675 Batteries (60 Batteres)

 NEW (60-pack) of Size 675 Maratone Zinc Air, Mercury Free Hearing Aid  Batteries. As with any "zinc-air" hearing aid battery that is "air  activated", it is highly recommended that you wait at least 60 seconds  after you remove the Protective Tab before turning on your hearing aid.  This will activate the battery and you will get the most out of it.  These items are not refundable once opened. At The Hearing Aid Battery  Club, you know you are buying safe, original replacement parts. Thank  you.
