Hearing aid batteries are produced in four sizes.  Hearing aid battery No. 10 (yellow), No. 312 (brown), hearing aid battery No. 13 (orange) and No. 675 (blue), which have different lifespans depending on the hearing aid model and technology.  Usually there are 6 batteries in each ring or battery pack.

Battery size does not affect the price and all four sizes have the same price.  For example, the price of Rayovac hearing aid battery No. 10 is the same as Rayovac hearing aid battery No. 13 (Rayovac).  Of course, according to the brand and the manufacturing company, its price may be slightly different.  It is worth noting that the longer the expiration date, the longer the battery life.
