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 ...

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 ...

Many of you have probably experienced a situation when when trying to charge a small portable device (smart band, smart watch) from your power bank, it is difficult to get 100% charged, and sometimes the power bank turns off after just a few seconds, leaving our device discharged. Why does a typical ...

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 ...

We are used to comparing the value of capacity, expressed in milliampere-hours [mAh], which is given in virtually all commercially available batteries.However, on disposable batteries, in particular typical LR6 AA, LR03 AAA batteries, specialized batteries, or those dedicated to hearing aids, such i ...

We present a practical guide that will allow you to get to know Ni-MH rechargeable batteries better. We recommend reading it to both beginners and advanced users.Have you ever had a fresh battery pack that doesn't want to charge when you take it out of the device, or maybe the charging turns off alm ...

Powerbanks are devices that have achieved great popularity in a few years. Manufacturers outdo each other by adding new features to devices, increasing their power, increasing their capacity, etc. The mentioned capacity of the powerbank is the main criterion for users according to which they choose ...

Hearing aids and cochlear implants of speech processors use a special type of batteries - zinc-air batteries, thanks to their unique design, combine high efficiency and small size. However, they require special treatment. We encourage you to read the following articles on the use of hearing batterie ...

More and more users, following the trend of environmentally friendly solutions, decide to replace disposable batteries, in particular the so-called AA/AAA "sticks" with rechargeable batteries that can be recharged multiple times. We buy branded, capacious Ni-MH batteries, invest in a good charger, a ...

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 ...

The article in "Puls Biznesu" describes the history of Baltrade and its current situation in connection with the developing COVID-19 pandemic. Michał Seredziński, Vice President of the Management Board, reveals what are the plans for the coming years."The Gdańsk-based electronics wholesaler is rapid ...

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 ...

During the holiday season, mosquitoes can be a real nuisance limiting the pleasure of relaxing together. There are more and more UV lamps available on the market, which help to control the number of insects in the vicinity with the help of the emitted ultraviolet light. Below we explain the principl ...

Has it ever happened to you that a new CR2032 lithium battery freshly inserted into the remote control refused to work? Or maybe the device immediately signaled a low charge level despite installing a new battery? If so, you probably like most people considered such a battery to be defective and use ...

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 ...
