- 5 Summary
- Lithium batteries are designed to store electrical energy. They use lithium salt as an electrolyte, which allows it to obtain the amount of ions needed for the electrochemical reaction between cathode and anode.
- Their use became widespread in the 90s, associated with the rise of portable technology. They are built from light components and come in compact and easy-to-use formats. They are very resistant to the ‘memory effect’, an issue that other types of batteries have.
- Although the standard and the most used format is rectangular, its structure can be modified and adapted to different devices, so there are cylindrical and even flat versions.

Shopping Guide: Everything you Should Know About Lithium Batteries
Comparing different types of batteries and their features is an important step when making a purchase, but other factors also must be assessed. The main one is to know the product we’re buying (in this case, lithium battery): understand what it is, what it is for and what it can offer us.
What is a lithium battery?
How does a lithium battery work?
What are lithium batteries used for?
Over the years, other uses for lithium batteries have been developed. Currently, they are also used to power hybrid or electric cars, although their battery life remains very limited. Today, lithium batteries are the most common and marketed device in technology market.
What are the advantages and disadvantages of a lithium battery?
What is the ‘memory effect’ and why don’t lithium batteries have it?
This is one of the biggest advances of lithium batteries over other types of batteries that were on the market and more popular some years ago, such as lead-acid and nickel ones. That is why lithium has easily gained ground in recent times over other types of batteries, because they are not subject to the ‘memory effect’ caused many problems and inconveniences to users.
What are charge cycles and how many does a lithium battery offer?
The life of the lithium battery is also linked to their charge and discharge cycles. Each cycle is understood as the time it takes to the energy accumulated in the battery from fully charged to discharge. Lithium batteries have an average life of 500 to 1,200 cycles.
What maintenance does a lithium battery need?
Among others, the main tips we can provide for proper maintenance are: avoid extreme temperatures (above or below 15 degrees), store them with a medium charge during non-operative times and do not keep them with 100% of the load for long periods of time.
How much do I need to buy a lithium battery?
Also, you must consider that some lithium batteries are universal and will be compatible with any device, regardless of the manufacturer, while technical specifications allow it. Others, however, are of exclusive use, more specific, complex and unique features.
Before buying a lithium battery, as with any other product, we must consider some variables. Failing to pay attention to these key aspects will lead us to making the wrong purchase. Next, we will try to detail and specify each of them in an understandable and enlightening way.
- Use and Compatibility
- Physical Characteristics
- Power and Voltage
- Charging Time and Duration
- Lifetime and Charge Cycles
Use and Compatibility
The first thing we have to be clear about is why we need a lithium battery. Certain electronic devices share features and power parameters. Thus, the same battery can be used in the TV remote, a wireless mouse or a toy car, for example.
That is not always the case. Each device will withstand a different voltage, and if we use the wrong batteries, two things can happen: the power will be insufficient (the device will not work) or excessively high (burning the device). Hence the importance of using the right battery, to avoid accidents and frustration.
In addition to technical or energy characteristics, we also have to identify the appropriate format from a physical point of view. Lithium batteries have very varied geometric shapes: flat, rectangular, cylindrical or rounded. Each one will fit in certain devices, but not in any or all.
Beyond compatibility and physical fit, there are other variables that we can assess. Then, if the format we need is rectangular, we will seek within the range of rectangular lithium batteries, the ones that have the exact size.
Additionally, compare the weight, looking for the lightest and most compact model.
Power and Voltage
Voltage can basically be defined as the force or pressure at which power goes out from the battery to the device. Each device will have a different voltage and, using the wrong battery can cause your device to not function properly (or at all), or may even damage it.
This means it is critical to use the battery with the correct power and voltage for your device. The output voltage range of lithium batteries is very wide, depending on the device to be powered. It is the basic feature we must pay attention to before buying a lithium battery.
Charging Time and Duration
First lithium batteries took more than 12 hours to fully charge and only offered a few hours of use. Today, charging times have been greatly reduced while hours of use after fully charged were proportionally extended. But there are still differences.
Therefore, we must pay attention to the milliamps per hour (mAh), which determine the battery life. More mAh means more duration. For example, the lithium batteries of mobile phones are today above 3,000 mAh, which a few years ago barely reached 2,000. Do not overlook this feature.

Lifetime and Charge Cycles
Another important technical aspect has to do with how long lithium battery will last. It is hard to determine time duration without associating it with the use, expressed as loading and unloading cycles. Lithium batteries are sensitive to the number of times they are recharged and stored energy is consumed.
The more charge cycles the technical specifications indicate, the longer the service life. Normally, they exceed 500 and can even exceed 2,000, but it is a very variable parameter depending on the type of battery and utility. The longer the useful life, the more profitable the investment made.
There are many types of lithium batteries, depending on a series of variables we tried to expose in this article. One of them, the main one, is what it will be used for. That is, the electronic device it will feed. Therefore, the features and needs of such device will condition the rest.
And what is the rest? Battery power, physical characteristics (shape, size and weight), the duration of the stored energy, the charging time or service life of the product, among others. All of them have to be considered before buying a lithium battery, after comparing several models with similar features.
