The term "battery" was first used in 1748 by Benjamin Franklin to describe an electrically charged glass plate. Between 1780 and 1786, Luigi Galvani demonstrated what we understand today as the basis of knowledge about electricity and electrical impulses, which was the foundation of later research b ...

Looking at the battery, we can see that it has two poles - one positive, marked "+", the other negative - marked "-". In the case of typical cylindrical batteries, such as R6/AA or R14/C (used, for example, to power flashlights or toys), the terminals are the ends of the battery. In car batteries, t ...

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 ...

The number of people affected by hearing impairments is growing all over the world. According to Hear-it.org data, as many as 16% of Europeans complain about the inconvenience of hearing loss.In the treatment of hearing loss, early detection of the defect is extremely important. In most cases, heari ...

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 an ...

It seems like a simple thing – replacing the battery, but there are a few aspects that are worth paying attention to to ensure a long battery life and not damage the hearing aid.Normally, your hearing aid will let you know that your battery life is approaching, for example with two beeps. These sign ...

We expect hearing aids and implants to perform reliably. In their use, it is extremely important to ensure high quality power supply. A good battery determines the sound quality and the time of use of the camera.This article presents a list of common questions we receive from customers and the answe ...

We invite you to the XXII edition of the Film-Video-Photo Fair on May 23-25, 2019 in the Expo Hall - Łódź (Łódź, al. Politechniki 4).At the Baltrade stand (stand No. D4) there will be an opportunity to get to know (and buy) the best batteries, accumulators and chargers - not only for cameras and cam ...

In this article, we quote the most important rules for the use of hearing aid batteries. ...

The battery life depends primarily on the power consumption of the hearing aid itself and the amplification level you set.The intensity of external noise is also important. The battery life will certainly be longer if the user remembers to turn off the camera when it is not in use (e.g. during slee ...

These batteries have protective stickers on the bottom.After removing them, wait at least 2 minutes before the battery is placed in the camera.This time is needed for oxygen to penetrate the battery - only then does the battery activate and reach the appropriate voltage to work. Failure to follow t ...

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 ...
