The best batteries on the market!

Forbes, one of the leading business and finance publications, has recently released their top picks for hearing aid batteries. Hearing aid batteries are ranked by many qualities such as service life, materials quality, and audio quality (stability) 

It is always good to make sure you have hearing aid batteries on you. You don’t want to be unable to hear during an emergency or even a long work meeting.

Chemistry: Zinc-Air

There are many different brands of rechargeable hearing aid batteries; more common brands are Power One, ZeniPower, Panasonic, NEXcell, Rayovac, Toshiba, iCellTech, Hear Clear, Duracell….. Ect. 

Generalmente las baterías recargables de ayuda de audiencia tienen una esperanza de vida de 4-5 años, Pero esto puede variar dependiendo de la marca, o que tamaño de batería que se necesite. 

ES MUY IMPORTANTE ASEGURARSE DE QUE BATERÍAS DE SU CONTROL DEL AUTOMÓVIL ESTÁ FUNCIONANDO, NO QUIERES QUEDARTE ABAJO DE LA LLUVIA Y NO PODER ABRIR SU AUTOMÓVIL.

Hay muchos tipos diferentes de baterías, asegúrese de obtener las letras correctas (Normalmente CR) y los números correctos también. MicroBattery Pro-Tip (Entendiendo las baterías de lithium coin): Las baterías de lithium coin generalmente se encuentran seguidas de un conjunto de números. La C en CR le permite saber que la batería usa una química de lithium. La R te permite saber que la batería tiene forma redonda. Los dos primeros números te indican el diámetro de la batería y los dos últimos números te indican la altura. Entonces, siguiendo esto, puede ver fácilmente que una batería CR2032 es una batería de química de lithium (C) con una forma ronda (R) que tiene un diámetro de (20) 20 milímetros. Esto se aplica a la mayoría de las baterías tipo moneda y de botón, pero tenga en cuenta que existen algunas excepciones, como las baterías CR2 o CR123A, que se consideran baterías cilíndricas de Lithium

IT IS VERY IMPORTANT TO MAKE SURE THAT YOUR KEY FOB BATTERIES WORK, YOU DON’T WANT TO GET STUCK OUT IN THE RAIN NOT BEING ABLE TO OPEN YOUR CAR.

First Sign: Worsening signal, you used to be able to open your car from the inside of your house and now you have to be up close to your car for the door to be able to open.

Second Sign: Over-Clicking, a key fob should only take one click to unlock doors.

Third Sign: Key Fob not working could be caused by the battery being dead.

Different types of batteries have different rechargeable battery life.  Battery life depends on the model and your usage. Heavy and constant use will drain a battery much faster than light and intermittent use. 

For example:          

Nickel cadmium (Nicad, NiCD) (1.5-3 Years) Cycle LIfe: 1,000+ Cycles

Nickel metal hydride (NiMH) (3-5 Years) Cycle Life: 700-1,000 Cycles  

Lithium Ion (2-4 Years) Cycle Life: 600-1,000 Cycles

Lead Acid (6 Months) Cycle Life: 200 Cycles ( Varies)

The importance of proper battery disposal

The average person throws away 8 batteries per year. Collectively, we dispose of over 3 billion batteries annually in the United States. According to Science Direct, the UK, with one-fifth of the US population, generates 30,000 tons of wasted general purpose batteries annually. Less than 2–3 percent of them are recycled. The interaction of the chemical constructs of these wasted batteries poses a threat to the environment. 

The availability of the nickel metal hydride battery played a crucial role in facilitating Europe’s banning of the nickel-cadmium battery in the EEC’s Battery Directive of 2009. Nickel-cadmium batteries (Ni-CD) along with lead-acid batteries currently represent the greatest environmental threat from energy storage devices. Lithium batteries are, to the surprise of some, quickly following suit. Lithium-ion batteries may be only mildly toxic, but factors including their size, sheer number, and their improper disposal, contribute to their addition to the list of polluting battery chemistries.

To be clear, the problem is not a particular battery chemistry. The issue is its disposal.

A LOOK AT LITHIUM BATTERIES

In a prior article, Battery categories and chemistries, we discussed the two battery categories, primary batteries and secondary batteries, with a brief summary of the common batteries in each group. We focused on alkaline batteries in our post, Role of primary batteries, and presented the broad family of lithium-metal cells, which together with alkalines, dominate primary batteries in both popularity and usage.

n this article we will take a closer look at primary battery types and delve just a bit more in some of the more recognized lithium chemistries available. Excluded from this post are three primary battery types that serve niche applications—zinc-air batteries mainly used to power hearing-assisted devices, silver-oxide batteries mainly used for watches, and zinc-carbon batteries which were superseded by alkalines in the 1980s but are still available for specialized needs. Available links to discussions on these batteries can be found at the end of this post.

Battery Hazards for Children

Batteries pose a variety of hazards to children including choking, toxicity, electric shock, and burns. There are thousands of different batteries on the market and all contain a variety of chemical agents. They come in various shapes and sizes, ranging from giant bricks to tiny cylinders. One of the most dangerous types of battery for children are lithium coin cell batteries, which are quickly becoming very popular among manufacturers due to their relatively small size and high performance. Being able to power a device with such a small battery is great and convenient for manufacturers and for users, but these batteries becoming so small pose a serious risk for children. The round shape of lithium coin cells and shiny metallic finish can be mistaken for a piece of candy or small food item by a child. Ingestion of a lithium coin cell battery can sometimes not be an issue as they can normally be passed through the system with little issue. In many instances, complications can occur which can be very serious and life threatening. The biggest hazard is the battery being logged in the esophagus, causing choking or even serious burns. If you suspect a child has ingested a battery or any other non-food item it is best to seek professional medical attention right away. 

PREVENTING HARM

I can remember hammering on a C-cell after an unsuccessful attempt to pry it open with a screwdriver. It was the 1970’s, and like most kids in their single-digit years, I was curious. I had no clue that my forceful attempt to discover what lies inside could result in a painful experience. Spring forward to 2020, I wonder if the potential hazard would have been recognized even by the average adult; awareness of existing dangers lurking in everyday products does not seem to have been quite as widespread then as it is now.

With today’s variation in battery compositions, it is important that we understand some of the hazards posed by their modern chemistries and some precautionary measures against them. My brute force attempt to open what I am guessing was either a zinc-carbon or an alkaline battery, might have been met with dire consequences had it been one of today’s battery chemistries.

Let’s take a look at a few battery types with regard to safety.

PROTECTING OUR CHILDREN

In the United States alone, 2,800 kids require emergency treatment for swallowing button batteries annually. That breaks down to approximately one child every three hours. In 2017, there were 1,986 ingested battery cases involving children under 6 years of age. I recently viewed a heartbreaking video published by Child Accident Prevention Trust (CAPT) about a Hampshire toddler, Francesca Asan, who tragically died from ingesting a button battery from a pair of 3D glasses stored in a cabinet.

With the development of more advanced battery chemistries and more batteries in the home to power our gadgets, serious injuries and deaths from their ingestion have multiplied by nine times in the last decade.

Hearing aid batteries typically come in 4 basic designations of sizes. The difference between different models of hearing aid batteries come from their physical size as well as the power and output of the battery. The 4 main sizes of hearing aid batteries are Size 10, Size 13, Size 312, and Size 675. Hearing aid batteries are conveniently color coded in order to easily identify the size of the battery.

All batteries should be kept out of children’s reach to avoid accidental battery ingestion.  Particularly prone to ingestion are the small, round, miniature batteries, often called coin cells or button batteries.  These batteries are composed of metals like zinc, nickel, silver, cadmium, and lithium.  Some contain concentrated solutions of caustic electrolytes, and even mercury.
