Batteries For Emergency Preparedness And Storage

As science and technology advances, electronic devices like smart-phones, tablets, laptops, digital cameras have become an intrinsic part of our everyday life, whether it is for personal usage or professional usage. So, making stock for extra batteries for emergency preparedness is also essential now. But you need detail information to consider which batteries will be best for you.

Alkaline and heavy-duty battery, which is known as a primary cell, works fine with TV remotes and other electronics that are used regularly. But it would not be wise to depend on these for long term use or on emergency.

Which Battery Should You Consider For Emergency Preparedness?

A little understanding of the battery capacity, recharge cycles and also discharge rates will help you to consider the excellent fit for your purpose and to save you money.

  • Battery capacity: The mAh (Milli Ampere hour) denotes the energy of the battery or the battery life. A battery with a massive mAh will run long. A primary cell disposable battery generally has 400 to 900 mAh, whereas a rechargeable battery can have the double or triple capacity.
  • Self-discharge: This is the rate at which the battery loses its stored charge. You will find this characteristic in almost all the batteries, though the rate varies from one battery to another. The discharge rate is dependent on several factors like storage temperature, how it gets charged, and battery types.

Nickel-based battery has the highest rate of decaying, whereas the lithium-based have the least.

  • Charging has a partial connection to the memory: The recharging impacts the memory of some batteries, especially the Nickel-Cadmium based ones. The memory may lose if the recharging happens after partial discharge. But it is practically impossible to every time recharge battery after a full discharge.
  • Charging cycles: There’s no such battery that lasts forever. After several times it gets recharged, it does not work. That number is termed as the charging cycle.
  • The charging cycle makes a crucial factor in determining the difference between shelf life and also the actual lifespan. For infrequent use, shelf life is essential. For occasional use, battery with a long lifespan is suitable for those which are used and also recharged every day.

Comparison Of Rechargeable Batteries For Emergency Preparedness

Low Self-discharge Nickel Metal Hydride (LSDNMH)

It is a popular choice for emergency storage. Though they are available in AA and AAA sizes, you will get adapters to fit them in C and D sizes. They have an average of 20 years of shelf life. Recharging does not impact the memory, and also the discharge rate is quite low. You can replace the alkaline batteries with it in most of the devices. These are a little expensive compared to the primary cell.

Nickel Metal Hydride (NIMH)

This non-toxic option is new in the market. Within a short period, it has become one of the favorite choices for the consumers because of its non-toxic nature and high charging cycles. They don’t even need any particular disposal. It is a suitable replacement for the alkaline variant.
