Rayovac Size 312 Extra Advanced Mercury Free Hearing Aid Batteries (80 Batteries)

On behalf of my husband who wears hearings aids:These hearing aid batteries have been a dependable choice for me. They activate quickly once the tab is pulled and consistently deliver clear, uninterrupted sound. I’ve found that each battery lasts several days with regular use, which is great for minimizing the hassle of frequent replacements.The packaging is easy to open and makes storing and handling the batteries simple, even for those with limited dexterity. I also appreciate that they’re clearly labeled and color-coded, so there’s no confusion when reordering.If you’re looking for hearing aid batteries that are reliable, long-lasting, and easy to use, these are a solid option.

Was using oem batteries purchased through my audiologist. Tried these and so far i have been satisfied with the life span and much better price point. Oh and the battery case is so convenient and easy to dispense. It has Rotating wheel that holds the batteries and a resealable dispensing door on the back side. The last supply of the oem batteries were extremely difficult to remove the packaging, it is what got me to look at this brand.

Quality item

I have been ordering these batteries for at least 10 years—just clicking on “Buy it again” in my Amazon order record whenever I was running low. I have always been very satisfied with them. However, my most recent order (Feb 2025) arrived in a new “child resistant” packaging that is an absolute deal-breaker.This new package, which looks superficially just like the old ones, is not merely child-resistant, it’s human resistant. Whereas on the old package, you merely had to bend down the tab on the back of the package, then (if necessary) turn the disk containing the batteries until a fresh one was visible through the window on the back of the package, and dump the fresh battery out.To get a battery out of the new package, you have to use (sharp) scissors to cut out a pie-slice-shaped piece of the whole package , and then insert something like the tip of a pocket knife between the two layers of plastic surrounding the battery, and pry those two layers apart, freeing the battery.When I realized all of this, I looked at my most recent order and checked out the ad listing. Sure enough, while the photo shows the old packaging, there is, in the description, the notification:“ • 100% NEW certified Child Resistant packaging. Make sure you are sitting down with your battery pack and a pair of scissors, ideally over a table. Carefully use the scissors to cut and open the pack and access the hearing aid batteries one by one. Think of this as like cutting a slice of a pie.”I sure wish I’d read that before reordering.I have been used to carrying one of the (old-style) battery packs in my wallet. I tried pre-cutting one the new packages into six pieces (still connected at the center), but if I pre-pried the plastic apart, the batteries fell out. If I left the prying for when I was actually trying to get a battery out, I had to wrestle with that process wherever I happened to be when a battery died…except for the time when I had to change a battery inside a performance hall that prohibits carrying things like pocket knives, and subjects patrons to a metal detector search at the door. I just had to try to hear the rest of the show with one hearing aid.Fortunately for me, I found in my dresser, an old, partially full pack of out-of-date 312 batteries that I purchased while traveling out of town a few years ago. This pack functions the same way the old RAYOVAC ones did. So, I emptied the out-of-date batteries into the “take to recycling” bag, and put new RAYOVAC batteries into the old packaging. I’ll just have to do that with the rest of the latest RAYOVAC shipment.However, the next time I need to replenish my supply of batteries, I’ll be looking for some that aren’t such a hassle to open.

love these as they are a great price-over retail stores- and the packaging is easy to open. Not childproof but my arthritic hands sure appreciate getting them out easily.

Product is great. Packaging is awful. Now it's "child proof" and is impossible to open for arthritic hands, even with scissors. Old packaging was perfect. Manufacturer should at least offer alternative packaging....I'm looking for an easier to open brand now !

They came as advertised and on time. I'm glad to be at least somewhat stocked up for now. Thank you!

Easy to open and use. They last 5 days. Kirkland now has child resistant packaging and it is very difficult to open.
