Frequently asked questions
What color tab is a size 312 battery?
Brown. Hearing aid battery sizes use a standard color code across every manufacturer — brown is 312, yellow is 10, orange is 13 and blue is 675 — so you can match the tab color on your old pack to be sure.
How long does a size 312 hearing aid battery last?
Typically three to seven days. Heavy Bluetooth streaming to a phone or TV shortens that noticeably, and so does a more powerful fitting. Leave the tab on until you are ready to use the cell, then let it sit for a minute before closing the battery door.
Are size 312 batteries interchangeable between brands?
Yes. Size 312 is an industry standard, so a Rayovac, Power One, Duracell or ZeniPower 312 will all fit the same hearing aid. Brands differ on run time and shelf life, not on fit.
