I found an AA LR6 alkaline battery with a capacity of 3000 mAh. Does this mean it can be normally charged to this capacity? Unfortunately, charging such batteries makes no sense and we definitely advise against such action - why? We explain in our article. ...

Unfortunately, not always. The answer to this question is not straightforward, as the simplest testers or chargers can only measure mAh from the charging process. If our charger does not have a dedicated discharging (load) or testing function, its mAh measurement will never be equivalent to the actu ...

The problem is complex, and the answer is of interest to both users and sellers who are dealing with complaints submitted by their customers. We will try to help all interested parties on this topic. ...

When choosing rechargeable batteries, the main criterion for our customers is capacity, possibly brand, and of course price. It has become established that the higher the capacity of such a battery, the better. Such batteries are also clearly more expensive than potentially weaker/less capacious cou ...

On the Internet, we can find a large number of tests of batteries and accumulators. Practically every few weeks we can come across a new news item, video, or mention of further tests. Often, the winner of one ranking performs very average or even poorly in other tests. What causes such a large discr ...

When we buy a battery with a capacity of 2600 mAh and a specified number of charge cycles of 500, we are convinced that with occasional use, we will be able to enjoy its maximum performance for many years. The stated capacity values and the number of charge cycles are often treated as guaranteed and ...

It often happens that when analyzing the technical data of a battery we are interested in, we see, for example, 2 different capacity values expressed in milliampere-hours - mAh. Where do these differences come from? What is typical capacity, minimum, maximum, nominal, rated? ...

Currently, there is a surge of various chargers on the market that, according to the manufacturer's assurances, allow for measuring the mAh capacity of our batteries. But is that really the case? In our article, we describe the most common traps, doubts, and mistakes made by users when measuring the ...

The modern everActive battery, which is the equivalent of a typical 9V block battery, has a declared capacity of 500 mAh, but the inquisitive will notice that it consists of two Li-ion cells with a capacity of 500 mAh each.So shouldn't the total capacity of this battery be set at 1000 mAh? ...

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 ...

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 ...
