Are laptop batteries lithium? Myth about NiCd laptop battery technology

If you have a laptop, its battery life is very good. This type of battery has found applications in consumer electronics, including PDAs and laptop under 200 Euro. They have gained wide popularity for economic and technical reasons, especially because of the great convenience and the difficulties involved.

Laptop battery charging

Lithium-ion batteries have replaced the nickel-cadmium (NiCd) batteries used in laptop launches and the nickel metal hydride (NiMH) batteries that have surpassed NiCd laptop battery technology. Because they are lighter than other laptop batteries, they charge longer than other technologies, and do not affect the effects of memory, and today dominate the laptop battery charging market. A typical lithium-ion battery is twice the energy density of a conventional nickel-cadmium battery. In addition, lithium-ion batteries have a single cell voltage of 3.6 volts, compared to 1.2 volt cells in nickel cadmium batteries.

the disadvantages associated with lithium-ion batteries include: the ability to launch a failed battery pack in bad conditions

However, the disadvantages associated with lithium-ion batteries include: the ability to launch a failed battery pack in bad conditions, and the ability of other battery technologies to be more sensitive to high-temperature environments and save charge, which is why Can damage batteries. They have been completely discharged due to failure, and in contrast to the strong link between battery malfunction and old battery chemistry building / discharge cycle, battery inheritance chemistry is deteriorating with age. Lithium ion computer batteries require circuitry to control the battery compartment, ensuring safe voltage and current levels, as well as ensuring that the battery temperature is within the safe operating range.

The cells of a compact lithium ion battery are typically similar to conventional rechargeable batteries. The plastic housing is housed in several cells, each connected to maximize the required voltage supply and storage quality (measured in millimeters). There are also parasitic lithium ion cells, but they are very small and are commonly used in devices such as cell phones, where weight and width must be considered first.

There are several factors that can affect the life of a lithium ion laptop battery. Keeping the battery in cold conditions prolongs its life as heat can quickly drain the battery. Manufacturers typically offer a storage temperature of approximately 60 F for long-term storage of lithium-ion batteries. These batteries, as mentioned earlier, do not protect the memory from a half discharge cycle, so a full discharge cycle is not required. In fact, running a battery on a semi-motorcycle helps extend its life span. Lithium-ion batteries, like older battery technologies, have a limited lifespan, but are relatively independent of their charging cycle, mainly due to their age. A typical battery lasts 2 to 3 years. This is true even if the battery is not used, so it is important not to replace the laptop before replacing it.

If one of your cell phone managers switches from computer to laptop, you will soon find yourself in a situation where you need to know about laptop batteries. Then, buy them sometimes. Here are some key tips:

Laptop Battery Summary: The most commonly used type of battery is nickel cadmium (NiCd, NiCad) chemistry, which dries very quickly and can handle heavy loads. But these chemicals are very toxic. Next-generation batteries, nickel metal hydride (NiMh, NiMH) batteries, now use nickel and rare metals as electrodes and potassium hydroxide. They are more environmentally friendly than nickel metal hydride, but they have a longer shelf life. The new type of battery is a battery made of lithium ion (LiIon, Li-Ion). Although smaller and lighter than NiCd and NiMH batteries, it offers the same capacity. Also, these batteries do not suffer from “memory effects” and have a low self-discharge rate.

Lithium polymer ion battery: This is the latest battery chemistry. Although they are similar to lithium ions, there are some important differences. Lithium polymer ion batteries use a thin plastic-like membrane such as electrolyte, resulting in significant weight loss and greater gravitational force than most types. They are used in universal laptop batteries. So when you need a new battery, look for a laptop.

SideKick, the backup and recharge gadget for your smartphones

SideKick KickstarterSideKick: A small gadget with so many features for your smartphone
SideKick is a special compact device available in Crowdfunding on Kickstarter designed by Flintu . We are talking about a product that includes a 300 mAh lithium ion battery designed in Japan, the ability to use genuine alkaline batteries to charge your devices, access a fast charging technology, save your files favorites through internal storage (up to 64 GB) and a cable for data transmission.

One of the most common problems present on a smartphone today is the autonomy. This is because the various companies are still unable to tackle the problem properly. So today, we are in the big powerbank to recharge our devices. SideKick was made by Flintu using high quality materials, predominantly anodized aluminum.

SideKick: A small gadget with so many features for your smartphone

We are talking about a safe gadget because inside there are some of the best quality batteries designed and manufactured in Japan . SideKick can be used with Android, iOS and Windows devices as it offers Lightning, USB Type-C and Micro USB connectors. In the case of the Lightning connector, the gadget has obtained the Apple MFI certification.

Inside there is a 300 mAh battery that allows you to use your smartphone for about 2 hours (obviously depends on what you need to do). Alternatively, you can use external alkaline batteries to increase your autonomy. For example, by inserting 2000 mAh lithium units , it will be possible to access 14 hours of autonomy.

The data transmission cable is of type 2.0 with a maximum speed of 480 Mb / s while it can support up to 2.1A. Internal memory, with exFAT file system, can be selected in 8/16/32/64 GB options and provides up to 23 MB / s read and up to 15 MB / s in writing.

Sony improves its external battery for smartphones

The new external battery for smartphones of Sony maintain the quality of its predecessor and become again one of the best solutions power pocket in the market.

The new models are the Sony CP-F1L and Sony CP-F2L, flat design, finished in aluminum and lithium ion polymer

The new models are the Sony CP-F1L and Sony CP-F2L, flat design, finished in aluminum and lithium ion polymer, which allows a quick charge of most of its capacity, which is important for those who always forget time to recharge this type of pottery.

The smallest model is the Sony CP-F1L, with capacity of 3,500 mAh coon in a body weight of 125 grams and a thickness of only 9.4 mm. The model with more capacity, no more and no less than 7000 mAh and 2.1 output, weighs slightly more (198 grams) and bulges three centimeters. In this case you have two ports USB outlet to recharge more than one gadget at a time.

No official price yet, it will come to Europe this month.
