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

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 ...

The AG13 alkaline batteries, SR44 silver batteries and 675 zinc-air hearing aid batteries have the same dimensions, i.e. 11.6 x 5.4 mm.Zinc-air batteries have a capacity many times higher than alkaline and silver batteries of the same size, they use a unique technology where oxygen absorbed from the ...

What to consider when choosing a power supply for your devices? In our opinion, the basic determinant of when to use a disposable battery and when to use rechargeable batteries should be the battery life of the device. If the battery is replaced every few months or longer periods of time, the legit ...

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 ...
