Batteries are part of everyday life – they power remote controls, toys, watches and even industrial equipment. Choosing the right type of battery can affect the comfort of using the device, its performance and operating costs. Knowing the differences between the different types of batteries allows y ...

The operating time of a flashlight is one of the factors significantly affecting the efficiency and reliability of its operation. This issue is particularly important in emergency situations, as well as during long-term use. The flashlight's operating time is largely influenced by the way it is powe ...

Has it ever happened to you that newly installed batteries or charged rechargeable batteries do not give any sign of life?The basket in which the batteries were installed has started to melt, or maybe there has been a battery spill in the power compartment of your device? In this article, we explain ...

As you know from our other publications, 1.2V Ni-MH batteries, in particular the typical R6 (AA) and R03 (AAA) batteries, function very well in most devices, being an ecological and economically justified replacement for disposable 1.5V batteries. On a daily basis, we use devices that tolerate worki ...

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 ...

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 ...
