How to Extend Your Rechargeable Battery Life

Rechargeable Battery Life

A few people wonder why their rechargeable battery life doesn’t endure for a long time. While the rechargeable batteries nowadays are already more heavy duty compared to their earlier versions, appropriate use, treatment, and handling is still necessary in order to get their maximum potential life cycle.

Here are some useful advice on how you can lengthen the rechargeable battery life.

First of all, it is crucial that you avoid overcharging your rechargeable batteries. Overcharging can significantly reduce the rechargeable battery life. To avoid overcharging, utilize timers and alarm clocks while charging so that you’ll be notified if it is already time to remove the batteries. One more solution is by utilizing special chargers like trickle chargers and smart chargers which can avert battery damage from overcharging. Overcharging may damage the cells of the rechargeable batteries, causing the condition referred to as voltage depression. This causes the battery is to be quickly drained even though it is just charged at a full capacity. A solution to this problem  is by putting the battery to another charge/discharge cycle.

One more great method of extending the rechargeable battery life is by only charging them prior to using them. This is especially suitable for nickel cadmium and nickel metal hydride batteries as these forms of rechargeable batteries lose their charge even when they are not being used by any device. This way, you don’t exhaust several unnecessary charge/discharge cycles, especially if you do not use the batteries regularly.

This do not apply to lithium-ions as well as low self-discharge nickel metal hydrides due to their very low self-discharge rates.

Also, storing nickel cadmiums and nickel metal hydrides in the freezer may be a good idea if you don’t intend to use them for a very long time as it will retain 90% of their charge even when stored for months. However, do not forget that you have to cool the batteries to a room temperature prior to using them once more.

Lastly, refrain from fully discharging your rechargeable battery. Contrary to popular opinion, it will not lengthen the rechargeable battery life as it may in fact cause cell damage because of reverse charging. Do a full discharge on nickel cadmium and nickel metal hydride batteries only if you believe that they have a voltage depression. As for lithium-ion batteries, use it for every 30 charge cycles or so on devices that have a fuel gauge (such as laptops), to ensure that the gauge is calibrated and accurate.

The Benefits of Using Nickel Metal Hydride Rechargeable Battery

Nickel Metal Hydride Rechargeable Battery

A nickel metal hydride rechargeable battery is another kind of rechargeable battery that can substitute nickel cadmium batteries. It is dissimilar from nickel cadmium batteries which makes use of cadmium for its negative electrode, since it uses a hydrogen-absorbing alloy instead. However though, these two kinds of rechargeable batteries both utilize nickel oxyhydroxide for its positive electrode. A nickel metal hydride rechargeable battery can be more useful in some situations over nickel cadmium as well as other types of batteries and here are several of the reasons why.

First of all, a nickel metal hydride rechargeable battery has a higher energy density which is about 50% more than a nickel cadmium rechargeable battery. This entails that this kind of battery has the ability to store a larger amount of energy using the same volume of battery cell.

The second benefit of nickel metal hydride rechargeable battery is that is has a low rate of internal impedance. The internal impedance or resistance pertains to the ability of a battery to carry current. A little internal impedance is a good trait of a battery as it signifies that it permits high currents so that more energy can be transmitted to the device at a faster pace. However, the internal impedance of a nickel cadmium batter is still less than that of a nickel metal hydride rechargeable battery.

One more benefit of a nickel metal hydride rechargeable battery is that it is a very durable battery. This battery can endure overcharge and overdischarge conditions. In addition, this battery can also work in various temperature conditions. This makes them a truly multipurpose and convenient batteries.

One of the main weaknesses of a nickel metal hydride rechargeable battery is that it has a very high self-discharge rate which gives it a shorter life span. However, there are now low self-discharge nickel metal hydride rechargeable battery that resolves this issue.

Lastly, a nickel metal hydride rechargeable battery is more environmental friendly than other battery types since it does not have the toxic metals like cadmium. This is significant during those instances when the battery is thrown improperly because it will not cause harm to the environment. Furthermore, this rechargeable battery can be financially-rewarding when recycled, which may promote this particular behavior among people.

Rechargeable Battery 101: How Do Rechargeable Batteries Work?

Rechargeable Battery 101

You may be thinking about how do rechargeable batteries work. Rechargeable batteries are also referred to as secondary cells because their electrochemical reactions can be electrically reversed. To learn more about how do rechargeable batteries work, continue on reading.

The primary thing that you need to understand about how do rechargeable batteries work is the mechanism of batteries. A battery has two terminals, a positive one and a negative one. When batteries are put on a device, a chemical reaction occurs within the batteries. The electrons gather on the negative terminal and head in the direction the positive terminal, producing electrical energy until the battery is depleted. This makes the batteries recommended emergency power source as they can be stored and keep their power until they are needed. Additionally, the flow of electrons between terminals is influenced by the battery’s internal impedance. A lower rate enables more electrons to flow at a faster pace, thus resulting in high currents.

The most basic idea behind how do rechargeable batteries work is that the battery is subjected to electrical current so that instead of the electron flowing from the positive terminal to the negative terminal (which is what occurs when the battery is being used), the reverse happens and power is restored. In other words, after the battery is charged, the electrodes head together again on the negative terminal of the battery so that you can utilize its energy once more.

One important issue in how do rechargeable batteries work is the so-called memory effect. Nickel cadmium rechargeable batteries are susceptible to this problem that happens when the battery is recharged before it was discharged by more than 50% of its power. This causes the battery to forget that it can be discharged all the way at 100%, so that in subsequent uses, the battery seems to be drained in an unexpectedly quick manner. This significantly diminishes the capacity of nickel cadmium batteries. A solution to this problem is by allowing the nickel cadmium batteries to fully discharge once every three weeks, in order to avoid the formation of large cadmium crystals.

Tips on How to Buy Rechargeable Batteries

Buying Rechargeable Batteries

Many people purchase rechargeable batteries without even thinking about the differences among each kinds of batteries. However, each type of batteries has its own benefits and downsides hence a specific type may be more ideal in particular situations than others. Here is a guide on how to buy rechargeable batteries so you get the most value out of your money.

The initial thing that you have to consider in how to buy rechargeable batteries is the different types of rechargeable batteries. There are three main types of off-the-shelf rechargeable batteries: nickel metal hydride batteries, nickel cadmium batteries, and rechargeable alkaline manganese batteries. A nickel metal hydride battery is the most pricey of them all because it has the highest energy density.

The nickel cadmium’s energy capacity lies between the nickel metal hydride and the rechargeable alkaline manganese. It has an adequate energy capacity but it is not as high as those of nickel metal hydrides and it can be unstable depending on the temperature. The rechargeable alkaline manganese battery is the most low-cost of the three but it also has the lowest energy capacity and it can only be charged for a couple of times.

The next thing that you have to understand on how to buy rechargeable batteries is type of device that where you are going to attach the batteries. Devices that uses a lot of energy especially those that have LCD screens such as digital cameras and mp3 players can benefit from the nickel metal hydride’s high energy capacity.

Meanwhile those devices that still need a fair amount of power like wireless mouse, battery-operated toys, and portable radios can utilize the less pricey nickel cadmiums. Devices that have minimal power requirements or those that are seldom used like remote controls and flashlights can operate on rechargeable alkaline manganese batteries.

The last thing that you have to take into account in how to buy rechargeable batteries is the estimated frequency of usage of the device where you intend to use the batteries. This is because different types of batteries have different self-discharge rates. Nickel metal hydride batteries self-discharge at the fastest rate at 30% per month even when not contained within a device. Next is the nickel cadmiums at 10% per month. Rechargeable alkaline batteries on the other hand can keep their charge for years.

Every battery type has its own benefits and while it mustn’t be the deciding factor when selecting a camera model, it is still helpful to learn which one is more ideal for particular situations. Here are some data about rechargeable camera batteries that you may find valuable when choosing a camera.

Most camera models nowadays come with proprietary rechargeable camera batteries. These are lithium-ion batteries that include a charger so that all that you require is already within the package. Once the battery is drained, you can just load it in the charger and once it is finished charging, you can shoot picture again. Apart from being practical to use, proprietary lithium-ion rechargeable camera batteries have a relatively low self-discharge rate which is estimated at around 5-10% per month, compared to nickel metal hydride’s 30% per month. Hence proprietary rechargeable camera batteries boasts a very long shelf life, which is ideal if you do not have to use your camera regularly.

Alternatively, the other class of battery that may be used for cameras are off-the-shelf batteries. Cameras typically require CRV3, CR2, AAA, and AA battery sizes. The main thing that you can gain from this class of battery is the flexibility it can give you. While proprietary rechargeable camera batteries are very convenient and ready to use, buying a spare one is actually very expensive, so most of the time, people do not bother buying an extra one.

Meanwhile, cameras that utilizes off-the-shelf batteries can be operated on both disposable and rechargeable camera batteries. While rechargeable camera batteries are more recommended for cameras, disposable camera batteries can be a cheap solution if ever you run out of energy and still need to shoot some more. The best class of rechargeable camera battery is the nickel metal hydride which contains a high energy density that is best for the high power requirements of digital cameras. Unfortunately though, in addition to the batteries, you also have to purchase the charger for off-the-shelf rechargeable camera batteries.

Benefits of Rechargeable Lithium Batteries

Rechargeable lithium batteries also known as lithium-ion batteries is a kind of rechargeable battery that utilizes intercalated lithium compound for its electrode material. This rechargeable battery is often used for medical devices, military hardware, and of course portable consumer electronic products. The popularity of rechargeable lithium batteries may be due to its benefits over other kinds of rechargeable battery and here are a few of them.

First of all, rechargeable batteries have the best energy density for any forms of rechargeable batteries.

They can store a lot of energy compared to other types of rechargeable batteries considering their size. The reason is that lithium is a highly reactive element which lets for a large amount of energy to be amassed in its atomic bonds. Additionally, they also are composed of a high open circuit voltage, which lets for more energy transfer at a lower rate of current. Hence it is recommended for devices that uses up a lot of energy such as mp3 players, computers, laptops, cameras, and the like.

An additional advantage of rechargeable lithium batteries is that they can be produced into a range of shapes and sizes, making them well-suited for many devices.

Furthermore, lithium-ion batteries are not heavy. That is the reason why they are recommended for medical devices since they need batteries that are not bulky and must be able to last for an extended period of time. Rechargeable lithium batteries are often utilized on cardiac defibrillators, neurostimulators, cardiac pacemakers, and drug infusion systems. Furthermore, there is a new type of rechargeable lithium-ion batteries, called lithium-ion polymer batteries, which can be made as thin as a wafer and yet still be flexible and reliable.

Last but not the least, rechargeable lithium, batteries have a very low self-discharge rate which makes it ideal for occasional use.

As a matter of fact, rechargeable lithium batteries can hold their charge and only lose around 5-10% of their energy for a month of storage, while nickel cadmiums and nickel metal hydrides can lose about 1-5% of their energy daily, even when they are not attached to the device. Furthermore, rechargeable lithium batteries can survive up to hundreds of charge/discharge cycles.

Basics of Rechargeable Alkaline Batteries

Majority of alkaline batteries that can be bought today are disposable ones but are you aware that there are also rechargeable alkaline batteries? These batteries, like the common disposable alkaline batteries, can be bought in a variety of sizes such as AAA, AA, 9-volt, D, and C batteries. Rechargeable alkaline batteries have a dissimilar composition than compared to typical rechargeable batteries such as nickel cadmiums and nickel metal hydrides hence they have a different usage. Here are several significant information that you need to know concerning rechargeable alkaline batteries.

A rechargeable alkaline battery is also called as a rechargeable alkaline manganese battery. The primary thing that you have to learn about these batteries is that their initial energy is even less than the ordinary disposable alkaline batteries. Additionally, every charge cycle will further lessen their energy capacity. The reason is that rechargeable alkaline batteries are characterized by high internal impedance, so that they are not capable of allowing high currents. This considerably impacts how this type of battery is utilized.

One more limitation of rechargeable alkaline batteries is that they only have a very brief life cycle. The key in lengthening the life cycle of this type of battery is through recharging it before the energy level gets too low. Discharging this battery by a smaller amount than 25% will let you charge it again for approximately a hundred cycles, by smaller amount than 50% it can be recharged for a few dozen cycles, while completely draining it will only allow you a not too many charge-discharge cycles.

Rechargeable alkaline batteries are ideal for two kinds of devices.

Low-drain gadgets like clocks, wireless mouse, remote controls, wireless some detector, and the like are very appropriate for this sort of rechargeable battery because they don’t use up too much power. Devices that are used periodically like flashlights, handheld electric fans, portable radios, emergency lamps, and so on also work well for this kind of battery since you don’t often use them. In addition, a rechargeable alkaline battery has maintained the alkaline battery’s capacity to preserve its charge for years due to its very low self-discharge rate compared to nickel metal hydride batteries. Unfortunately, this battery is not recommended for devices that uses too much power like cameras, wireless drills, and so on.

Tips on Charging Rechargeable Batteries

Charging rechargeable batteries is an essential factor that influences the life cycle of this kind of battery. Rechargeable batteries can be unpredictable at times and so in order to utilize its maximum potential, you need to understand the proper way of charging rechargeable batteries. Here are some charging guidelines that can help you lengthen your rechargeable battery life cycle.

With numerous types of chargers that may be purchased today, there are now a lot of ways of charging rechargeable batteries. Each type of charger of course has its own advantages over another and therefore it may be more useful in certain situations than the others. There are three major rates of charging which is determined by how long the electrical current is applied to them: the overnight or slow charging which is around 14 to 16 hours, the quick charging which is about 3 to 6 hours, and the fast charging which can be accomplished in less than an hour. Though fast charging and quick charging are easier than overnight charging, it causes the batteries to become more prone to overcharge because a higher current is applied on the batteries.

Overcharging must be averted when charging rechargeable batteries because it can damage the cells. A good technique when charging rechargeable batteries is employing timers and alarm clocks. These common devices can help you remember if it is already time to turn off the chargers.

There are also specially-designed chargers that can help you extend your rechargeable battery life. One of them is the universal charger that comes with a sensor that can determine the type of battery that is being charged so that the right amount of current is applied.
