Has it ever happened to you that a new CR2032 lithium battery freshly inserted into the remote control refused to work? Or maybe the device immediately signaled a low charge level despite installing a new battery? If so, you probably like most people considered such a battery to be defective and use ...

Do you know how your toys, meters, cameras, chargers, flashlights, etc. actually work? - what do they do with batteries, rechargeable batteries, do they work safely and in accordance with accepted standards?Are your rechargeable batteries completely safe when left for a long time in your favorite to ...

The memory effect is characteristic of older Ni-Cd batteries.  The effect of this unwanted phenomenon was a reduction in the usable capacity of the battery.The battery, when discharged, only partially "remembered" the moment of charging. During later use, it became increasingly difficult to use ...

Definitely not. Completely discharging the Ni-MH battery before each charge effectively reduces its life. Regular battery discharge was recommended for old, virtually unavailable nickel-cadmium (Ni-Cd) batteries. Performing a forced deep discharge cycle eliminated and minimized the risk of the ...

In December 2019, our everActive Pro Alkaline batteries were tested for performance by an accredited testing laboratory in Poland. The Central Laboratory of Batteries and Cells in Poznań (CLAiO) is a specialized scientific unit with many years of experience in the field of chemical power sources. T ...

EverActive UC-100 and UC-4000 chargers have nothing to hide. From now on, their data sheets are supplemented with detailed characteristics of charging courses for typical batteries.The new data sheets are another, in addition to independent tests, confirmation of the high quality of everActive devic ...

PrincipleZinc-air batteries are unique in their design. The name itself indicates that air plays a special role in them. It is worth knowing what this technology is all about, and consequently, how to take care of this type of batteries and what their service life is. In this article, you will learn ...

Compact Flash cards were first introduced in 1994 by SanDisk Corporation. They provide full PCMCIA-ATA functionality (which in practice means that every Compact Flash card is simply a PCMCIA card, but smaller!) and ATA/ATAPI-4 compatible TrueIDE functionality. At present, they are the most common st ...

Nowadays, they are rarely used. Previously used mainly in Sony and Ericsson devices. At the moment, microSD cards with appropriate Memory Stick adapters are most commonly used.Types of Memory Sticks:The Memory Stick PRO features increased data transfer speeds and higher storage capacity. Memory Sti ...

Initially, flash drives offered capacities comparable to floppy disk drives, but the rapid technological development of flash memory caused that it quickly exceeded ZIP drives in terms of capacity, and now it is comparable to hard drives. At the moment (2019), flash drives with capacities of up to 4 ...

EEPROM (Electrically-Erasable Programmable Read-Only Memory) is a type of non-volatile computer memory. Also referred to as E²PROM. The EEPROM memory, unlike the EPROM memory, can only be erased using electric current. The number of writes and erases is limited, depending on the type and manufacture ...

Lithium-ion cells are the future of powering portable and wireless electronics – they are found in smartphones, MP3 players, remote-controlled models, etc. Their feature They are usually characterized by small dimensions and flat or cylindrical shapes. These inconspicuous cells can store twice as m ...

Alkaline batteries, thanks to their readiness for immediate use after purchase and thanks to their energy retention for a relatively long period of time, were a better alternative to traditional rechargeable batteries in the past. What has changed after the introduction of the new generation of rech ...

Lithium 'button' batteries are often used as power for the smallest portable devices (calculators, electronic dictionaries, etc.) - and for memory backup in similar devices (including BIOS memory backup in desktop computers). In lithium technology, batteries are also made in typical AA and AAA stick ...

The popular name of this type of battery comes from the alkaline (alkaline) solutions used in them as an electrolyte. Introduced to the market in the early 1960s, alkaline batteries quickly gained popularity, becoming the most important competitor to zinc-carbon batteries - this trend has been espec ...

Ni-MH batteries did not enter mass production for a relatively long time - although hydrogen is very well suited for the anode, the design of cells using hydrogen requires absolute tightness and high pressure inside the cell. It was not until the late 1960s that it was discovered that alloys of some ...

Here you will find explanations of the terms most commonly used in connection with batteries and chargers; Not sure what a term means or how cell capacity is measured? You don't know what internal resistance, termination current are, and the term CC/CV sounds like a cipher? Is the 'primary' battery ...

The term "battery" was first used in 1748 by Benjamin Franklin to describe an electrically charged glass plate. Between 1780 and 1786, Luigi Galvani demonstrated what we understand today as the basis of knowledge about electricity and electrical impulses, which was the foundation of later research b ...

Looking at the battery, we can see that it has two poles - one positive, marked "+", the other negative - marked "-". In the case of typical cylindrical batteries, such as R6/AA or R14/C (used, for example, to power flashlights or toys), the terminals are the ends of the battery. In car batteries, t ...

In PCWorld.pl you will find a review of one of the latest everActive products - the UC-4000 charger - a professional and universal processor charger for Li-ion, Li-FePO4, Ni-MH cells. Supports all common sizes of rechargeable batteries. The product has been awarded the recommendation "Proven product ...
