Batteries using Precautions

What are batteries?

The scientist who first discovered the principles by which the battery operates is the Italian Alessadro Volta, and the first battery was manufactured in the late 19th century and since then batteries have become an important source of energy for many appliances in the household and industry. A battery consists of one or more electro chemical cells that convert the chemical energy stored in the battery into electricity.

What categories of batteries are there? There are two basic categories of batteries: Disposable (primary) and rechargeable (secondary) reusable and rechargeable batteries.

Can all batteries be charged?

No. Only those batteries that have a special chemical composition (Ni-Mh, Ni-Cd, Li-ion; Litium polymer, etc.) and which are intended for recharge may be charged. Such batteries must be marked “rechargeable”.

Do not attempt to recharge batteries that are not intended for this purpose!

Why don't all batteries have the same shelf life and capacity?

Battery life and capacity depend primarily on the chemical composition of the battery. Batteries in their chemical composition can be different: zinc-carbon, alkaline, lithium, zinc-air, Ni-Mh, Ni-Cd, Li-ion ... etc.

Turn off the devices while not in use.

If you are not going to use the device for a long time, remove the batteries from the device.

Dispose of batteries in a dry place and at normal (room) temperature and do not expose them to the sun or other heat sources. Do not leave batteries in the car.

Use rechargeable batteries until they are completely discharged, and then recharge without interruption until they are fully charged.

Do not combine old and new batteries or different types of batteries in the same device.

What Is Battery Formation And Why Is It Important To Do It?

With rechargeable Ni-Cd batteries and Ni-Mh batteries, it is important that you first charge the batteries fully before using them for the first time (do not interrupt charging), it may be the best time to do this overnight. If these batteries are already in the device where you are using them (laptop, camera, cordless phone, mobile phone, etc.), then have that device turned off during the first charge. When the batteries are fully charged, turn off the charger and use the device (without recharging the battery) until the batteries are completely discharged. Only then can you recharge the batteries as needed. This first cycle of charging the battery to the end and draining the battery to the end is called battery formation. In this way the so-called battery is removed from the battery. Memory effect, so batteries that are not fully charged for the first time will not have the capacity to be fully charged the next time, no matter how long we charge them.  

·     How can I improve the battery life of a cordless phone?
Cordless phone batteries (like most other rechargeable batteries for other devices) can usually be recharged about 1000 times according to the manufacturer's declaration. If you return your cordless phone to the charger after each phone call, it is likely that your battery will lose capacity in less than a year. However, if you only put your phone in the charger once every 3-4 days, you can expect your battery to last 3 to 4 or more years. In short: the less you put your phone in the charger, the longer the battery will last!  

·     What type of batteries should I get for my device?

To properly select the batteries for your device, please read carefully the manufacturer's instructions that came with your device.  

·     Can batteries be dangerous and what precautions should I take?

Batteries contain various chemicals, some of which can be aggressive or dangerous to health. In the event that the battery leaks, take care not to allow the liquid from the battery to come into contact with skin or eyes. Otherwise you will need to seek medical attention. Keep them away from young children, eliminating the risk of children swallowing them and poisoning.

Do not dispose of batteries in a fire. Some combustion batteries can produce toxic gases and vapors.

Do not charge non-rechargeable batteries.

Do not open or disassemble the batteries, some of the charged batteries (eg lithium) may be explosive in contact with air.

What should I do with spent batteries?

Do not dispose of batteries with other trash. Batteries belong to the group of large pollutants. They contain heavy metals that can contaminate soil and water to a great extent, and thus reach the food we bring into the body. The presence of heavy metals in food or water can have serious and lasting effects on our health. Take your used batteries to any specialist battery store, regardless of type or purpose. Most such stores have the authority to collect spent batteries and hand them over to recycling centers. You should be aware that for major pollutant batteries, the state mandates an environmental fee that is included in the cost of new batteries, so that each time you buy new batteries, a portion of the price you paid for those batteries is intended to be collected, disposed of and recycled. battery when they become waste one day.

Why do rechargeable batteries get really warm when I remove them from the charger?

It is perfectly normal for batteries to be very warm (up to 55C) when charged intensively as well as during intense discharge. If they get so hot during charging or use that you cannot hold them in your hands, know that the charger or the device in which you are using them is not working properly, and have the charger or device serviced. Otherwise, the use of such a charger or device may be dangerous (fire, electric shock, casing melting, etc.).

What are the batteries that are labeled "Ready to use" or "Pre charged"?

These are the latest generation rechargeable batteries that are ready to use immediately as soon as you buy and unpack them. Their feature is not only that they are factory-charged (and older generation rechargeable batteries are also factory-charged) but, above all, that the batteries remain nearly full even during storage for two, three or more years. Also, when using batteries, when you recharge them, they will have the same feature of staying full for a long time. All other rechargeable batteries, whether they have just left the factory or you have recharged them, if they last for a couple of weeks, will lose more than 50% of the rechargeable capacity, so you have to recharge them even though you have not used them since you last recharged. The first company in the world to patent and launch such batteries is the Japanese company Sanyo with the Eneloop series of batteries.

How does temperature affect battery performance?

When cold, the batteries provide less power, and vice versa, provide higher power at higher temperatures. When it comes to storing or disposing of batteries, it is recommended to keep it at room temperature.

Now I discuss the difference between "ordinary", alkaline and lithium batteries

They all belong to the group of primary, non-rechargeable batteries. Zinc-carbon batteries are "ordinary", have less capacity, after some time of battery usage, electrolyte leakage can occur and the storage period is up to two, two and a half years at most. Alkaline batteries are of higher quality, give a stronger and longer power supply, are protected against leakage, shelf life is up to 7 years. The most technologically advanced are lithium batteries. They provide even larger and longer lasting power, have a shelf life of up to 10 years. They can leak, have less weight and can be used under extreme temperature conditions (-30C to + 70C). The relationship between price and quality is most often on the side of alkaline batteries, so this category of batteries is one of the best selling batteries.
