Review: great product and value - The batteries last about a week so this pack is good for about a year. EASY dispensing...NO SCISSORS required!! packs are easy to store everywhere (pocket, desk drawer, wife's purse, glove box, etc). on 3rd box and so far all batteries have worked and lasted as expected. Aid is 'on' all day, every day. I don't sleep with it in.. Review: The best HA batteries bar none - My wife has used hearing aids for years and it has been a constant frustration for her to have to replace her batteries so often. She's a mobile woman on the go and she loves hooking up her hearing aids directly to sound sources (like her phone, or the tv). This, however, drains normal Energizer or Duracell batteries within a day or two, three if she's very lucky. Compounded with that is both the high price of name brand batteries and their poor manufacturing quality which leads to a very high number of duds. So not only do you spend over $1 per battery for the name brand, but you end up throwing 20-30% of them away because they simply don't work. Then about two years ago I saw these batteries and saw the reviews and thought I'd get them for her. I figured they were cheap and worth the experiment. Much to our surprise, these batteries (which are sometimes 1/4 the price of the name brand) are far superior to the name brand batteries. In two years she hasn't had a single dud. Not one. We've kept track. On top of that these batteries are *powerhouses*. They last her, even with all her connectedness, at least a week. These batteries are simply amazing. I can't recommend them enough. Just buy one pack. Give them a try. I promise you won't regret it. When you look at the overall cost of HA batteries from the name brand, we were spending nearly $10 a week just in batteries. Now we are spending about $.80. In today's economy, you just can't beat that. tldr: -Super powerful & long lasting -Very high manufacturing quality (no duds) -Great value -You must try them ## Features - Long Lasting, Stainless Steel Case - Will not rust like all other hearing aid batteries that are made out of Tin - Top of the line hearing aid batteries in the "Comfort Pack" - All Power-One batteries are subjected to strict safety and quality checks - Winner of the Stiftung Warentest consumer product award for 02/2018 (ausgabe) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B001AVZAIK | | Antenna Location | Hearing Aid | | Battery Capacity | 170 Milliamp Hours | | Battery Cell Composition | Other Than Listed | | Battery Cell Type | Other Than Listed | | Battery Weight | 50 Milligrams | | Best Sellers Rank | #37,229 in Health & Household ( See Top 100 in Health & Household ) #25 in Hearing Aid Batteries & Chargers | | Brand | Power One | | Compatible Phone Models | Any hearing aids that use a size 312 battery | | Customer Reviews | 4.1 out of 5 stars 8,241 Reviews | | Global Trade Identification Number | 00885813538458, 04008496341801 | | Item Dimensions | 0.39 x 0.39 x 0.2 inches | | Item Weight | 40 Grams | | Manufacturer | Varta | | Model Name | Varta Powerone P312 | | Model Number | 312 braun | | Number of Batteries | 60 Product Specific batteries required. | | Recommended Uses For Product | Hearing Aid | | Reusability | Single Use | | UPC | 699107369440 799360128850 794645523122 699107367613 885813538458 793936807545 | | Unit Count | 1 Count | | Voltage | 1.4 Volts | ## Product Details - **Battery Capacity:** 170 Milliamp Hours - **Battery Cell Composition:** Zinc - **Brand:** Power One - **Number of Batteries:** 60 LR44 batteries required. - **Recommended Uses For Product:** Hearing Aid ## Images ![Size 312 Hearing Aid Battery No Mercury, 60 Batteries - Image 1](https://m.media-amazon.com/images/I/61NsUCMgJtL.jpg) ![Size 312 Hearing Aid Battery No Mercury, 60 Batteries - Image 2](https://m.media-amazon.com/images/I/61VQbmMxv7L.jpg) ![Size 312 Hearing Aid Battery No Mercury, 60 Batteries - Image 3](https://m.media-amazon.com/images/I/41Lor38A4uL.jpg) ![Size 312 Hearing Aid Battery No Mercury, 60 Batteries - Image 4](https://m.media-amazon.com/images/I/61WYt80wMmL.jpg) ![Size 312 Hearing Aid Battery No Mercury, 60 Batteries - Image 5](https://m.media-amazon.com/images/I/61Z4REqiW6L.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: How are mercury free different from the others?** A: Mercury free is pretty much all you will find these days. They are different from older batteries in that they use oxygen from the air to produce power, which is why there is a sticker on them covering a small hole to keep them from discharging in storage. You need to wait 1 to 2 minutes after removing the sticker before trying to use them, to give them time to charge up. **Q: What is the voltage?** A: 1.45 **Q: Is anyone using these batteries in a Starkey over-the-ear hearing aid? I would like to confirm they will fit before placing an order.** A: I use a 312 battery in my Starkey hearing aids that fit over my ears. The hearing aid manufacturer says to use this particular product. I have also sampled other 312 batteries that I purchased in the grocery store and they fit the hearing aid too. Any 312 should fit. I have found so far this brand to be the longest lasting battery I have used. **Q: Are these batteries rechargeable ?** A: No. Although any battery can be recharged, this battery was not designed with the built-in safeguards for recharging. ## Customer Reviews ### ⭐⭐⭐⭐⭐ great product and value *by E***N on February 10, 2026* The batteries last about a week so this pack is good for about a year.

Disgusted *by C***S on April 26, 2026* I stopped buying Duracell after having been informed by a Duracell agent that the Activair product is NOT made by Duracell. (FALSE ADVERTISING) Power One got pretty good reviews so I gave them a try. The brand on the first package out of the box was Starkey, NOT Power One. Okay, my hearing aids are made by Starkey and they're very high end. Only one problem. They were all dead: Every. Single. One. Of. Them. DEAD! So I'm to assume that an Amazon worker substituted them with an old Starkey package because they ran out of Power One? All dead. NEXT: Open a child-resistant Power One package. HA! "Child Resistant" is right! It took an air chisel, a chain saw and a blow torch to get into the package! WT the living H? The reason I switched from Duracell was this: In my last order, I was shorted a package. I ordered 60 (qty) 312 batteries, I received 54, missing a package of 6. Amazon wouldn't rectify it so I went to the seller. I was never compensated for the discrepancy. As for the Power One's, the 30 day window for return has expired so I'm stuck with them. Fortunately, I saved the Duracell dispensers because they are easy to operate, and plan to transfer the Power One batteries to the Duracell dispensers. At the rate that it took me to get one battery out of the Power One dispenser, I'll be here all day. I'll be shopping elsewhere for my next order. Addendum: I am bleeding from my attempts to open the Power One dispenser. ## Frequently Bought Together - Power One Size 312 Hearing Aid Battery No Mercury, 60 Batteries - Wax Guards for Oticon ProWax MiniFit Hearing Aid Supplies Replacement Wax Filters, Oticon Hearing aid Supplies (5 Packs/ 30 Pcs). - Power One Zinc p312 hearing aid battery,60 pcs pack --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/9104518-size-312-hearing-aid-battery-no-mercury-60-batteries](https://www.desertcart.jp/products/9104518-size-312-hearing-aid-battery-no-mercury-60-batteries) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-05-20*
