Rechargeable Battery Basics: Long-Term Storage

It is a given that food will eventually go bad when it is bought. You can be sure to check the expiration dates on your food and other products. You are also aware of the places food should and shouldn't be stored. Did you know that batteries work in the exact same way?

These mini power cells, just like food products are perishable. They start to deteriorate as soon as they are manufactured. There are many ways to store and keep these mini power cells. These are the steps you need to take to prolong the battery's life.

A rechargeable Lithium golf cart batteries should be kept at 60 degrees Fahrenheit. They lose some of their charge as they sit. Self-discharge is the process of a battery losing its capacity while it is not being used. Different types of power cell have different self-discharge times. Nickel-containing power cells discharge the fastest. Nickel-Metal Hydrate and Nickel-Cadmium rechargeable batteries will discharge slightly faster than the others.

It is possible that you have heard it said that it is a good idea for your batteries to be kept in the fridge. It is not always true. You don't need to refrigerate your pets if you live in a moderate climate where the average room temperature is around 60 degrees. The refrigerating them will prolong their lives, but it is not really worth the effort.


- You live in very hot conditions. A battery can lose only about 20% in one year even if it is kept at 85 degrees. It will lose 1/4th of its life if it is kept at 100 degrees.

- You store Nickel Cadmium (NiCd), or Nickel-Metal Hydrate(NiMH) power cell batteries. They will lose some of the capacity each day if they are not kept in a refrigerator or at 70 degrees room temperature. You may not have any problems if you can keep them somewhere that is cooler than that.

Refrigerating your batteries can make them last longer. However, it is better to keep them at room temperature for a few hours before you use them.

Acid-based batteries should be kept at full charge. Half charge or 40% should be kept for nickel and lithium-based power cells. You will get better performance when you use them.

Do you feel like you are being bombarded with a lot of information at once? It can be confusing to understand battery technology, so let us break it down. Below are some guidelines that you can follow.

A cool and dry area is the best place to store your batteries. Keep them in the fridge if your room temperature is above 60 degrees. Before using, allow them to come up to room temperature. Keep power cells out of the freezer.

Keep the lithium and nickel-based rechargeable batteries at half charge. They will last a lot less if they are full charged. The exact battery type will vary, but generally around half-charged or 40% is sufficient. Keep lithium batteries with no charge out of reach. You should charge the battery a little before you store it, if it's below 0.

Lithium batteries are not as long-lasting as other types. So make sure you only use them when they're needed. While it is okay to keep a few extras on hand, it is not worth buying a lot and storing them until you are actually using them. There won't be any more charge after that point.

Follow the instructions manuals to ensure that heavy-duty, lead-based power cells are properly maintained. These manuals will provide guidelines regarding storage, including how to charge them and what conditions they should store under.
