One of the most used batteries in the world which many of us don't even know much about is our cell phone batteries. Many questions come to mind when dealing with a cell phone battery and to answer all those, you need to know a little about the batteries themselves. Most of our cell phones batteries are made up of lithium ions. The reason lithium ion is most commonly used is because it is light and can pack a lot of energy by itself.
The lithium ions are broken down into two more parts consisting of electrodes and electrolytes. The lithium in the batteries are very reactive, so cell phones contain a safe form of it called lithium cobalt oxide. These molecules pull electrons towards themselves when the battery is being charged and when the phone is being used, the power is provided by the release of these electrons.
A battery's capacity is highly dependent on its use. If the cell phone is being used more often and has many other processes running, it will discharge quicker. Hence, it is advised to take caution with your battery to ensure it lasts longer.
A good way to keep a tab on your battery's life is by installing an application that allows you to keep an eye on the life of your battery.
Controlling the power
Keeping a check over your cell phone's battery is very important. This is because the lithium that is contained inside is very reactive. If it gets too heated, it could cause some serious damage to your cell phone and maybe even to you. Cell phones consist of a small technology inside that allows the phone to charge to its complete ability and then puts a stop to power. However, if you feel that your phone is losing the ability to do so (you can tell if the phone starts to get warm every time you charge it), you will need to take it off charge as soon as it is complete.
Frequently asked questions
Will overcharging the battery cause damage?
When the environment around the battery is hot or it starts to warm up from the heat of the power, the lithium ions start to deteriorate. This causes the battery to lose some of its charging capabilities. Otherwise, the modern smartphones come with a technology that allows them to only absorb as much power as required. This statement could not be held true for older phones that do not possess the ability to recognize when the battery has been fully charged.
Do batteries lose their capacity with time?
Batteries do tend to lose their capacity over time. Cell phone battery operates in cycles, and one cycle is equal to one full discharge. A battery has the capacity to withstand 300 to 500 cycles and after that, it will start to lose its battery capacity which, in turn, leads to it losing its life. It is possible for you to save the cycle by not letting your battery completely discharge in one go.
How can you save your cell phone battery?
You can save your cell phone's battery through many ways. Some will even help make your battery life stronger.
- Close all processes that are not being used
- Turn off the location and weather apps
- Turn off the push notifications
- Add a battery optimizer to your cell phone
- Lower your screen’s brightness
Should the phone battery be recharged once it has been used above 75%?
For lithium-ion batteries, it is not feasible to charge for a long period of time as it only uses up their charging cycles. It is better to recharge your phone when it has been partially discharged; around a 50% discharge would do just fine. It would prolong the battery's life, making it more efficient.
Will turning off the Wi-Fi save the battery life?
Keeping other processes running is more likely to deteriorate your battery life than keeping Wi-Fi and Bluetooth on. They do not require as much power as they used to before, but turning them off would at some small level help save your battery. 3G and 4G will drain your battery life much faster than Wi-Fi and so does a cell phone searching for a radio signal. Hence, turning on the airplane mode will probably save your battery.
Should you charge your phone when you first get it?
Before smartphones were common, cell phone batteries used to contain nickel cadmium. It was due to this that batteries were highly dependent on how they were charged; the use of the battery and how you took care of them also mattered a lot. But with smartphones came the modern lithium-ion batteries, which do not require too much care. You can use them straight out of the box until you feel the need to charge them.
It is not a well-known fact, but cell phone batteries can be reconditioned as well. The way to recondition them is fairly simple. You will start by discharging your batteries completely. Once that is done, turn your phone back on and let it turn off itself. Once that has been done, recharge your phone completely and let if charge more for a few hours. After that, you need to repeat the steps at least 3 more times. The battery will be reconditioned and will regain most of its capacity.
What the future holds
Many scientists have started looking for an alternative to lithium-ion batteries with the main aim of them being able to provide a longer battery life, longer usage time, and an overall more efficient battery. Some have now discovered supercapacitors, which have the ability to perform much better than lithium-ion batteries. There is still a lot of research to be done regarding alternative battery types and only the future will tell what we are in store for.Learn More
It is the battery that is responsible for providing power to all the different electrical components of a car. Speaking in general, it is a rechargeable 12-volt lead-acid battery that is meant to power the electrical systems within the vehicle. What this means is that there are many different chemicals inside the battery, all of which go through several processes and reactions when the battery is in use. The same chemical reactions are, however, reversed when the batteries are being recharged.
Purposes of a car battery
The very first purpose of car batteries is that they are meant to ignite the starter motor and the ignition system. For those who don't know, the starter motor is basically an electric motor that is responsible for getting the main gas engine started. On the other hand, the ignition system is where the mix of gas and air is ignited for the production of combustion required for the engine to keep running.
Apart from that, the car battery also runs the overall electrical system of the car. The most important component in this regard is the lights. The 12-volt battery basically powers all the lights in the car including the trunk light, interior lights, headlights and even the dashboard light. It is for this reason that the battery is going to get drained and you will not be able to start your car if you leave the lights on.
Dealing with a dead car battery
When a car battery dies, there really isn't much that you can do to start it. Although there are many different reasons as to why your car may not start, as long as you hear that clicking noise and don't have ignition, there's a good chance that you are dealing with a dead battery. What the clicking sound implies is that the starter is working but the battery is not fulfilling its purpose. In case the starter is dead too, you will not be able to hear the clicking sound.
What this leads us to is the question, why is it normal for car batteries to get drained so quickly when the lights are left turned on but can power the lights for as long as needed when the engine is running? Well, to begin with, it takes nearly 12 entire volts for the car to get started, which means that if your battery is at 11.1 volts, there isn't much chance that your car will run. Also, the thing with car batteries is that they continue to recharge themselves as they run, which is why the batteries don't run out as long as the engine is running.
How does a car battery get recharged?
All cars come with an 'alternator' which recharges the battery by producing energy through the mechanical motion of the engine and the alternator belt. On the whole, the engine is started by the car battery and it then recharges it while running on gasoline. It is for this reason that it is vital for you to run your car for a while before shutting it off again once you jump start it. The alternator has a small computer attached to it that tells it to keep on charging the battery and when to stop. The reason why this is attached to the alternator is that in case the battery gets overcharged, it may start producing hydrogen which will, in turn, explode the battery.
Of course, you would now want to know why there is a need to purchase a new car battery so frequently. This is because car batteries do not have the potential to continually hold the charge as much with the passage of time. For the record, 12-volt batteries can actually hold up to about 13 volts, but as time goes by, their ability to do so diminishes significantly. The day that the batteries cannot hold more than 12 volts, it's time for you to head out there and get yourself a new battery. It is fairly common for people to refrain from keeping an eye on how much charge their car battery is holding up. In the long run, they learn about its inability to do so when they start their car and it doesn't start at all or has a weak start. It is for this reason that it is best for you to keep a tab on the amount of charge that your car battery is holding up so that you don't have to worry about dealing with a dead one.
Reconditioning a car battery
Replacing a car battery can be rather expensive. On the other hand, reconditioning one is much cheaper and easier. All that you need for this purpose are Epsom salts, a voltmeter, and distilled water. This procedure is going to help you get your battery to start but will only work a few times.
To begin with, use a voltmeter and see if your car battery is registering 12 volts on it. As long as it reads between 10 and 12 volts, there is a good chance that your battery will restore to full operation. Using distilled water and Epsom salts will help you recondition your car batteries in this case. However, for 10 volts or lower, you are just going to end up wasting your time.
With that, make sure that you take a few precautions when restoring your battery. Remember, car batteries contain sulfuric acid, which deems it even more necessary for you to be cautious. When working on your battery, make sure that you do so in a properly ventilated area. Also, while doing so, put on rubber gloves and goggles to ensure your safety. In case you end up with acid on your skin, wash it off immediately with lots of water and make sure that you are nowhere close to open flames.Learn More
