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 ...

The world is increasingly aware of the negative impact of waste on our environment. In recent months, you may have heard about the announcement of the withdrawal from the sale of traditional batteries by one of the largest retail chains. As an alternative, we are increasingly using rechargeable batt ...

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 ...

Eneloop is a popular and respected brand of Ni-MH batteries. Currently, it belongs to the Panasonic concern, although many remember that they were once signed with the Sanyo brand. We would like to reassure the latter right away - the batteries have not lost their quality and are still produced in t ...

Do you know how your toys, meters, cameras, chargers, flashlights, etc. actually work? - what do they do with batteries, rechargeable batteries, do they work safely and in accordance with accepted standards?Are your rechargeable batteries completely safe when left for a long time in your favorite to ...

Many of our customers still believe that the slower we charge a battery, the better it is for its condition and life. Unfortunately, it is very easy to unknowingly destroy your batteries. If we charge new AA batteries with a current of 200-300 mA, we certainly do not use their full potential, and we ...

The memory effect is characteristic of older Ni-Cd batteries.  The effect of this unwanted phenomenon was a reduction in the usable capacity of the battery.The battery, when discharged, only partially "remembered" the moment of charging. During later use, it became increasingly difficult to use ...

Definitely not. Completely discharging the Ni-MH battery before each charge effectively reduces its life. Regular battery discharge was recommended for old, virtually unavailable nickel-cadmium (Ni-Cd) batteries. Performing a forced deep discharge cycle eliminated and minimized the risk of the ...

Alkaline batteries, thanks to their readiness for immediate use after purchase and thanks to their energy retention for a relatively long period of time, were a better alternative to traditional rechargeable batteries in the past. What has changed after the introduction of the new generation of rech ...

Ni-MH batteries did not enter mass production for a relatively long time - although hydrogen is very well suited for the anode, the design of cells using hydrogen requires absolute tightness and high pressure inside the cell. It was not until the late 1960s that it was discovered that alloys of some ...

Here you will find explanations of the terms most commonly used in connection with batteries and chargers; Not sure what a term means or how cell capacity is measured? You don't know what internal resistance, termination current are, and the term CC/CV sounds like a cipher? Is the 'primary' battery ...

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 ...

If you want to replace disposable batteries with Ni-MH rechargeable batteries, it is worth following a few rules that will allow you to take full advantage of the capabilities of the new cells. Following a few simple rules will allow you to use your rechargeable batteries optimally, economically and ...

Charging Ni-MH batteries with the lowest possible current is not always the most beneficial for their service life. With modern automatic chargers, the assessment of when the battery is fully charged is largely dependent on the value of the charging current.The best charging result is achieved with ...

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 ...

Every European manufacturer is obliged to provide reliable information on the capacity of batteries.The technological maximum limit of currently achieved capacities for Ni-MH batteries is about 1100 mAh for R03/AAA ('small fingers') and about 2700 mAh for R6/AA ('ordinary fingers') - although even t ...
