Ni-MH rechargeable batteries cause much more problems when assessing the current state of charge than alkaline or Li-ion batteries.While in the case of typical disposable batteries or Li-ion rechargeable batteries, we can orientate the level of charge of the cells and their condition based on the vo ...

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 ...

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 ...

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 ...
