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 ...

The end of the year is a traditional time for summaries. Based on our sales data for 2024, regarding retail sales on hurt.com.pl and total sales including wholesale, we have prepared a subjective ranking of Ni-MH and lithium-ion battery chargers for you. ...

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 ...

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 ...
