Controller Rechargeable Battery Maintenance

Storing a rechargeable battery is easy once you know how to do it. Here are some tips for storing rechargeable batteries:

1. Separate Brand New and Old Batteries

Keep old (or partially used) and new batteries separate at all times. Why? If you have a lot of batteries to power your equipment, it's preferable if they're all the same age and capacity. Sort your spent and new batteries into different containers or plastic bags, and date them. Batteries of various sorts should be kept apart from one another. They can react and produce a short if they're kept together.

2. Place Them Far Away From Metal Objects

Metal things and batteries aren't the greatest of friends. Batteries may short-circuit if they come into touch with metal. Instead of metal, batteries should be placed in plastic, glass, wood, or any other material. A custom-made battery storage box is another option. Batteries should not be stored with other metal objects in the same container. This applies to all batteries, not just coin batteries, which are more susceptible to short circuits. This also explains why, if you wish to carry money, you should avoid carrying loose batteries in your pockets.

3. Store Them in Their Original Packaging

If at all possible, avoid opening the container until you're ready to use the batteries. Keeping them in their original packaging has various advantages. In their original packaging, your new batteries will be shielded from environmental factors such as humidity, which can degrade battery power. If unsecured batteries come into contact with one another, or if the terminals come into contact with other metal objects, short-circuiting can occur. If you retain them in their original packaging, disaster is unavoidable. It won't be possible to mix new and old batteries either, which is a good thing!

4. Keep Them Safe at Room Temperature

The majority of people keep them at room temperature in a dry place, which is excellent. For most batteries, a temperature of 15 degrees Celsius is optimum, although a bit warmer won't hurt. Direct sunlight, on the other hand, should be avoided at all costs because heat is the number one enemy of batteries.

5. Make Sure it’s Not Too Humid

Condensation, corrosion, and leakage can all be caused by high humidity. As a consequence, you should stay away from it at all costs. Although it is a good idea to put batteries in the refrigerator, the high humidity increases the danger of condensation. If you must store the batteries in the freezer, place them in a vapor-proof container and let them out for at least 24 hours before using. If you store your batteries properly, their shelf life will be extended and the risk of a fire will be considerably reduced.

How to charge rechargeable batteries?

Charging rechargeable batteries is pretty easy. Here are the steps to do it:

1.Make sure the charger you're using is compatible with the batteries you're going to charge. Most rechargeable batteries are charged using an A/C converter that plugs into a standard household outlet. The terminals on these chargers are available in a range of sizes, from AAA to D. Depending on the type of batteries you want to charge, you can usually find a charger suitable for the size of batteries you want to charge at any electronics or hardware store.

2.Only use the appropriate batteries in the charger. You run the danger of corroding and ruining your charger if you try to recharge single-use batteries. Only recharge batteries that have a clear "rechargeable" label. Replace any single-use batteries that have died with rechargeable batteries.

3.Connect the charger to an electrical outlet. On most A/C adapter chargers, a power light should come on automatically or by flipping a "On" switch. You may start charging your batteries as soon as any power indicator lights turn on.

4.Place each charged battery in the charger in the correct order. The positive (+) ends must be connected to the charger's positive terminals, and the negative (-) ends must be attached to the charger's negative terminals.

5.Allow the batteries to charge completely. When the batteries are fully charged, most chargers will change the light from green to red or vice versa. If the procedure is interrupted by unplugging the charger cord or removing the batteries too soon, the battery life will be drastically reduced.

6.Remove the batteries after the charging process is finished. Overcharging, especially with rapid charge chargers, is the most common cause of battery life loss.

Should rechargeable batteries be fully discharged?

It depends on the type of battery. For example, lead batteries should never be fully discharged. Lead acid batteries should never be totally emptied before being refilled, but nickel cadmium batteries should only be almost depleted.

What if you have a lithium-ion battery? If you have a lithium-ion battery, Complete discharges and recharges are preferable to shallow discharges and recharges because they put less strain on the battery, extending its life. When your battery is drained, Battery University recommends merely charging it to 50% capacity before recharging it. When charging a lithium-ion battery, don't charge it all the way up to 100%.

The same goes with storage. The battery should be completely charged before being stored. If the battery will be stored for more than a year, it should be fully charged and drained at least once a year to ensure that it remains in excellent working condition. 

So, everything depends on the type of battery you’re having and the situation you’re using it for. We hope that this article provides an insight on how you can maintain your rechargeable battery properly and keep it longer than you should!
