Buying Guide for the Best 312 Hearing Aid Batteries
Choosing the right hearing aid batteries is crucial for ensuring that your hearing aids function properly and provide you with the best possible hearing experience. There are several key specifications to consider when selecting hearing aid batteries, and understanding these can help you make an informed decision that meets your needs. Here are the main factors to consider when choosing hearing aid batteries.Battery SizeBattery size is one of the most important factors to consider when choosing hearing aid batteries. Hearing aids come in different sizes and require specific battery sizes to function correctly. The most common sizes are 10, 13, 312, and 675. Each size is color-coded for easy identification: yellow for size 10, orange for size 13, brown for size 312, and blue for size 675. It's important to choose the correct size for your hearing aid model to ensure proper fit and function. Check your hearing aid manual or consult with your audiologist to determine the right size for your device.
Battery LifeBattery life refers to how long a hearing aid battery will last before it needs to be replaced. This can vary depending on the size of the battery and the power requirements of your hearing aid. Generally, smaller batteries (like size 10) have shorter lifespans, typically lasting 3-7 days, while larger batteries (like size 675) can last up to 20 days. Consider your lifestyle and how often you use your hearing aids when choosing a battery with the appropriate lifespan. If you use your hearing aids frequently or for extended periods, you may prefer a battery with a longer life to reduce the frequency of replacements.
Battery TypeThere are different types of hearing aid batteries, with the most common being zinc-air batteries. Zinc-air batteries are activated by exposure to air, which means you need to remove a tab to start the battery. They are popular because they provide a steady voltage and are relatively inexpensive. Rechargeable batteries are another option, offering the convenience of not needing to replace batteries frequently. However, they may require specific hearing aid models and charging equipment. Consider your preference for convenience and environmental impact when choosing between disposable zinc-air batteries and rechargeable options.
Shelf LifeShelf life refers to how long a battery can be stored before it starts to lose its charge. Zinc-air batteries typically have a shelf life of 2-3 years if stored in a cool, dry place. It's important to check the expiration date on the packaging to ensure you are using fresh batteries. If you don't use your hearing aids every day or if you buy batteries in bulk, consider the shelf life to avoid using expired batteries that may not perform optimally.
Environmental ConsiderationsEnvironmental considerations are becoming increasingly important for many consumers. Zinc-air batteries contain small amounts of mercury, which can be harmful to the environment if not disposed of properly. Some manufacturers offer mercury-free options, which are more environmentally friendly. Rechargeable batteries are also a greener choice as they reduce the number of disposable batteries that end up in landfills. If environmental impact is a concern for you, look for mercury-free zinc-air batteries or consider investing in rechargeable hearing aids.
