Have you ever experienced that a freshly inserted new CR2032 lithium battery in the remote control refused to work? Or maybe the device immediately signaled a low charge level despite having a new battery installed? If so, like most people, you probably considered that battery defective and useless. ...

Do you know how your toys, meters, cameras, chargers, flashlights, etc. actually work - what they do with batteries, rechargeable batteries, whether they operate safely and according to accepted standards? Are your rechargeable batteries completely safe when left in your favorite toy or other devic ...

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

Definitely no. Completely discharging a Ni-MH battery before each charge effectively reduces its lifespan. Regularly discharging batteries was recommended for old, practically unavailable nickel-cadmium (Ni-Cd) batteries. Performing a forced deep discharge cycle eliminated and minimized the ris ...

In December 2019, our everActive Pro Alkaline batteries were tested for performance by an accredited research 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 ...

Chargers of the everActive brand UC-100 and UC-4000 have nothing to hide. From now on, their data sheets are supplemented with detailed characteristics of charging cycles for typical rechargeable batteries. The new data sheets are another confirmation of the high quality of everActive devices, along ...

Principle of operation Zinc-air batteries are unique in their construction. The name itself indicates that air plays a special role in them. It is worth knowing what this technology is about, and consequently, how to take care of such batteries and what their lifespan is. From this article, you wil ...

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

Currently rarely used. Previously mainly used in Sony and Ericsson devices. At present, microSD cards along with the appropriate Memory Stick adapters are most commonly used. Types of Memory Stick cards: Memory Stick PRO features increased data transfer speed and larger capacity. Memory Stick D ...

The pendrive initially offered capacities comparable to those of floppy disks, but the rapid technological development of flash memory has caused its capacities to quickly surpass ZIP drives, and it is now comparable to hard drives. Currently (2019), pendrives with capacities up to 4 TB can be found ...

EEPROM (short for Electrically-Erasable Programmable Read-Only Memory) is a type of non-volatile computer memory. It is also referred to as E²PROM. Unlike EPROM memory, EEPROM can only be erased using electric current. The number of write and erase cycles is limited, depending on the type and manufa ...

Lithium-ion cells are the future of powering portable and wireless electronics – they are found in smartphones, MP3 players, remote-controlled models, etc. Their characteristic features are usually small dimensions and flat or cylindrical shapes. These unassuming cells can store twice as much energy ...

Alkaline batteries, due to their readiness for immediate use after purchase and their ability to retain energy for a relatively long period, were previously a better alternative than traditional rechargeable batteries. What has changed with the introduction of new generation rechargeable batteries? ...

Lithium 'button' batteries are often used as power sources for the smallest portable devices (calculators, electronic dictionaries, etc.) - as well as for maintaining memory in similar devices (including maintaining BIOS memory in desktop computers). Lithium technology also produces batteries in sta ...

The popular name for this type of battery comes from the alkaline solutions used in them as an electrolyte. Introduced to the market in the early 1960s, alkaline batteries quickly gained popularity, becoming the main competitor to zinc-carbon batteries - this trend has been especially noticeable rec ...

Ni-MH batteries were relatively slow to enter mass production - 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 only in the late 1960s that it was discovered that alloys of certain metals co ...

Here you will find explanations of the terms most commonly used in connection with batteries and accumulators as well as chargers; do you not know what a term means or how to measure the capacity of cells? Do you not know what internal resistance is, termination current, and does the term CC/CV soun ...

The term "battery" was first used in 1748 by Benjamin Franklin to describe a charged glass plate. In the years 1780-1786, Luigi Galvani demonstrated what we now understand as the foundation of knowledge about electricity and electrical impulses, which was the basis for later research by inventors su ...

Looking at the battery, we can see that it has two terminals - one positive, marked with "+", and the other negative - marked with "-". 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. I ...

In PCWorld.pl you will find a review of one of the latest products from the everActive brand - the UC-4000 charger - a professional and universal processor charger for Li-ion, Li-FePO4, Ni-MH cells. It supports all popular sizes of rechargeable batteries. The product received the recommendation "Ver ...
