New users of chargers may have doubts when their new, advanced Ni-MH battery charger (popular AA batteries) is supposed to charge 4 batteries at 1A, while it is equipped with a power supply rated at 1A. After all, 4 batteries charged at 1A require a total of 4A of current, right? ...

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 ...

When we buy a battery with a capacity of 2600 mAh and a specified number of charge cycles of 500, we are convinced that with occasional use, we will be able to enjoy its maximum performance for many years. The stated capacity values and the number of charge cycles are often treated as guaranteed and ...

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 ...

Just like last year, we decided to test suspicious batteries described as Eneloop Pro, offered through the largest shopping platform in Poland. The price – really "bargain" – over 30% lower compared to current prices from official distribution – what could go wrong ;) ? Last year (2021) we alread ...

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 ...
