As many of you know, consumer batteries from the Panasonic brand have become difficult to obtain in existing sales channels due to disruptions at the distribution levels by the end of 2025. Therefore, the availability of batteries from this brand in Poland and other EU countries has become uncertain ...

On the Internet, we can find a large number of tests of batteries and accumulators. Practically every few weeks we can come across a new news item, video, or mention of further tests. Often, the winner of one ranking performs very average or even poorly in other tests. What causes such a large discr ...

Batteries and accumulators everActive are subjected to periodic laboratory tests. In 2022, another test was conducted by a certified research unit - Intertek Semko AB. Intertek Semko AB, located in Sweden, is an elite laboratory engaged in, among other things, testing batteries and accumulators. It ...

Do you remember our test from a year ago, where we tested "occasionally" purchased Eneloop batteries? The products turned out to be counterfeit, with performance about 25-40% worse than the originals available in our warehouse. We are supplementing our test with a self-discharge test – measuring cap ...

Currently, there is a surge of various chargers on the market that, according to the manufacturer's assurances, allow for measuring the mAh capacity of our batteries. But is that really the case? In our article, we describe the most common traps, doubts, and mistakes made by users when measuring the ...

The problem with alkaline batteries is that in devices with high power consumption, they are very often inefficient and discharge quickly (the voltage drops very quickly) and need to be replaced frequently. Ni-MH batteries, on the other hand, are ideal for devices with high power consumption. Unfort ...

Recently, we have received alarming information from our customers and readers that questionable quality Panasonic Eneloop batteries have appeared on the market. After analyzing the information received, we made a controlled purchase of batteries on one of the auctions on the most popular site in Po ...

This time in our lab, we decided to thoroughly test the capabilities of block alkaline batteries, Ni-MH rechargeable batteries, and Li-ion in the 9V size (the designation for the alkaline battery is 6LR61). The test involved measuring capacity, energy, and recording discharge curves at currents of 5 ...

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 ...

Among many of our customers, there is still a belief that the slower we charge a given battery, the better it is for its condition and lifespan. Unfortunately, it is very easy to unknowingly damage your batteries. If we charge new AA batteries with a current of around 200-300 mA, we can be quite sur ...

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 ...

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 ...

This is a question that arises very often in our daily work. It is generally believed that Ni-MH batteries cannot replace disposable batteries due to their lower voltage. However, this applies only to certain devices - usually those with low power consumption and typically in configurations where ba ...
