Many types of modern small technology works only because they put all of us familiar batteries. But today's technology needs a lot of energy, so the usual battery, provided that the device is used quite often, does not last long. The decision to buy the battery pack every time is rather stupid, because it has long been such a thing as a battery charger.
The thing that is needed in every house
Many have already heard of such a thing as a universal battery charger, but did not rush to buy it, because by some criteria this device was referred to as expensive. But if you approach from the other side and calculate the total number of batteries that are now functioning in your house, plus all the batteries, multiply the number by the required number of battery replacements for a year, then multiply by the average price of one battery, you can get a pretty tidy sum,which will be several dozen times higher than the price of such a charger. And this we will receive only the amount that we spend for one ye
How does this device work?
Batteries-batteries and chargers are things that exist in any modern house, because only the discharged batteries and an ordinary outlet are needed for the device to work. That is, first you put the batteries in the charger, after you connect it to the network and very soon you will get really working batteries that will not differ from the new ones just purchased.
's battery charger will also be an indispensable thing in any office, because there is a technology that works from conventional finger batteries. Just imagine, now you do not have to send any of the subordinates to the store for a couple of batteries, just take the battery charger for AA batteries, put them on charge and very soon you will get absolutely workable "fingers".
In addition, it is in the offices there is a lot of technology that works from finger batteries, that is, in fact the charger will be used regularly.
A little about the basic characteristics of the
The average battery charger for finger batteries can charge from one battery and more( that is, you do not need to fill all slots to start charging).Basically they are designed for one type of battery, but there are also combined options( for example, for AA and AAA batteries), but such models will be a bit more expensive.
In most modern models, you are sure to see LED indicators that will notify you about the state of the charge and its termination. A good charger for rechargeable batteries must necessarily have "protection from re-plying", because an excess charge only harms the battery. Excessive charge can simply "kill" the capacity of the battery, that is, after several cycles of charge-discharge, the battery will be completely inferior.
Why not buy from untested implementers?
Many people think that such a product as a battery charger can be bought in ordinary markets, that is, to take cheaper models, which very often do not even have supporting documentation. Deciding on a similar step, you must answer for yourself in advance of the results, because the product without a guarantee is the absence of any possibility of repair or return of money for a poor-quality device. If it "spoils" the batteries that you put in it, it's certainly not a big loss, but you'll be sorry for your own money, which will simply be thrown out into the air.
Features that should be in any modern model of universal charger
Buying a battery charger for AA batteries, you may wonder whether the model you are offering "automatically" can automatically choose the level of the charging current. Only such models are able to charge batteries absolutely without harm to them, that is, their power is preserved.
Another important characteristic - a good battery charger for AA batteries should "cope" with batteries like NiCd and NiMH and it is desirable to do it simultaneously and qualitatively.
Interesting features that are worth knowing about
Some chargers can "quicken" batteries. This process is not just a normal charge, but a renewal of the capabilities of a finger battery, which has already gone through several charge-discharge cycles. This is how you can achieve the renewal of the battery power level, which is already slightly worn out. The charger simply restores the battery, making it again the most rechargeable and hardy.
Universal charging with adapters
Today, more and more popular are universal chargers, which even in the kit have a lot of adapters. That allows you to charge not only AA batteries, but also a technique with a suitable connector. This is very convenient when you know that the batteries, and the phone and, for example, the player can be charged at the same time or alternately and will never have to search for the home or office of the required charger or adapter cord.
Pros and cons of a similar purchase
So, in order to finally find the answer to the question of whether it is worth buying a universal charger for rechargeable batteries, it is necessary to count all its advantages and disadvantages.
The main advantage is, of course, savings. Not only the money that was to be spent on batteries is saved, but also the time it takes to find the right battery in the stores.
The second advantage is the ease of use. A universal battery charger is not a technique to work with which you will have to carefully study the instructions, because even a child can cope with it.
The third main advantage is absolute safety for all members of your family, and for nature. Everyone knows that the disposal of finger batteries is a costly process, and most people just throw them away, thereby infecting our nature with heavy metals. The charger will allow at least a little to save our ecosystem.
Speaking about the shortcomings frankly, they simply do not exist, if we mean certified models that will last even longer than their warranty period.
Only you decide whether to buy such a universal charger for yourself, but one thing is certain - you will never regret such an acquisition when you see the full level of its usefulness.
