On the Internet we can find a large number of battery and accumulator tests. Practically every few weeks we can come across a new news, video, or mention of further tests. Often, the winner of one ranking performs very mediocre or even poorly in other tests. What is the reason for such a large dispe ...

everActive batteries and rechargeable batteries are subjected to cyclical laboratory tests. In 2022, another test was carried out, performed by a certified research unit - Intertek Semko AB.Intertek Semko AB, located in Sweden, is an elite laboratory dedicated to, m.in the testing of batteries and a ...

Do you remember our test from a year ago, where we tested "bargain" Eneloop batteries? The products turned out to be counterfeit, with a yield about 25-40% worse than the originals available in our warehouse. We supplement our test with a self-discharge test – measuring capacity after 13 months of s ...

There is currently a rash of different chargers on the market, which, according to the manufacturer's assurance, allow you to measure the mAh capacity of our batteries. Are you sure? In our article, we describe the most common pitfalls, doubts and mistakes made by users when measuring the capacity ...

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, our customers and readers have been receiving disturbing information that Panasonic Eneloop rechargeable batteries of dubious quality have appeared on the market. After analyzing the information received, we made a controlled purchase of rechargeable batteries at one of the auctions on the ...

This time in our lab we decided to thoroughly test the capabilities of block alkaline batteries, Ni-MH and Li-ion batteries in size 9V (alkaline battery designation 6LR61). The test consisted in measuring capacitance, energy and recording discharge curves with currents of 50 mA, 100 mA, 200 mA and 5 ...

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 ...

Many of our customers still believe that the slower we charge a battery, the better it is for its condition and life. Unfortunately, it is very easy to unknowingly destroy your batteries. If we charge new AA batteries with a current of 200-300 mA, we certainly do not use their full potential, and we ...

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 ...

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 ...

This is a question that comes up very often in our daily work. It is usually believed that Ni-MH batteries cannot replace disposable batteries due to their lower voltage. However, this applies only to some devices - usually with low power consumption and usually in a configuration where batteries a ...
