Choosing the correct battery is among the most important things to exploit the potential of your electro -helpful, but orientation among the products offered by the market can sometimes be not easy for a less experienced audience that is consequently risks buying a battery that does not respond to your own Expectations: Find out with our advice how easy it is to find the perfect battery for each electro -helpment.


How a rechargeable battery works

 

Often in the vast rechargeable batteries market or electrical charge accumulators, the consumer finds himself disoriented in the choice of the right battery for his own electro -helpment. This happens above all because of the poor technical knowledge of the battery functioning. This guide allows you to know the structure, the components but above all the functioning of your charge accumulators so as to allow you the best possible choice.

Rechargeable batteries are substantially batteries whose electric charge can be restored through the application of a specific and adequate electricity.
In fact, the fundamental characteristics of a battery are its ability, expressed in amps for now or ah, and the tension to the terminals, expressed in Volt or with the abbreviation V.

As a rule, each accumulator bears the type of voltage and capacity in its name or model; It is advisable to always pay attention to these parameters when choosing the battery to entrust to your electro -helpment and if you choose the charger for its charging.

Lithium ion battery, nickel-cadmium or nickel-metal hydruro: what confusion?

 

Li-ion battery, Ni-CD batteries, Ni-MH accumulators: what does this mean?
On the market exist different types of batteries that differ not only for voltage And electrical ability, but above all for chemical composition And size.

Among the secondary batteries for most sold electroutensils, lithium-ion batteries are counted, nickel-metal or nimh nickel-metal batteries and nickel-cadmium or ni-cd batteries. But what's the difference?

 


Lithium ion battery

 

The lithium -ion rechargeable battery is a type of accumulator commonly used in consumer electronics: come on laptops to cell phones, many electro -helpments or appliances are now fueled with this type of technology. But let's see in detail how it works.

Lithium batteries can be manufactured in different sizes and shapes, this thanks toextreme versatility of lithium ions. This feature makes these batteries an efficient top -up tool and an effective optimizer of the work space. The lithium battery is very light equivalent batteries manufactured with other components. This is due tohigh charge density of lithium ions And to the fact that lithium requires less intermediaries for storage, so as to leave room more to the charge.
The accumulators of charge to lithium ions they do not have any memory effect and show a low rhythm of auto-scarica, certified approximately around 5% on a monthly basis. This rate of self-scarb is mainly due to the internal consumption of the voltage monitoring circuit.
Among the disadvantages of lithium ion battery there is the presence of degradation even if it is not used. A lithium battery should never be downloaded under a certain tension so as to avoid irreversible damage. 
Consequently, it is important to check that the lithium batteries are equipped with a special circuit that turns off the battery if it should descend under the default threshold. A further problem related to lithium -ion batteries is due to overheating. If these are left near excessive or not very ventilated heat sources, there is a risk of their overheating and a consequent escape of dangerous liquid. Normally, a good lithium current accumulator requires the presence of different safety systems such as a thermal switch that prevents overheating in case of overload, and a safe with relief valve to control the internal pressure.

Nickel-metal battery hydruro or ni-mh

 

The nickel-metal battery or improperly called nickel-metalhydrate is a model of accumulator similar to nickel-cadmium (ni-cd) but in which the anode, the one who absorbs hydrogen, is a league instead of the cadmium. The cathode for both types of battery remains nickel. 
The accumulator to the nickel-metal hydruro or ni-MH has Two or three times the ability of the homologous (equal dimensions) to the Ni-CD and a less significant memory effect
The most common applications for this type of batteries include consumer electronics such as digital cameras but also hybrid products such as new generation cars.
They very often replace nickel-cadmium batteries if the electro-helpment requires greater power power current.

Nickel-cadmium or ni-cd battery

 

A very popular type of rechargeable accumulators is the nickel-cadmium. This type of battery is mostly used with electro -helpments and consumer appliances, in toys etc.
Ni-CD batteries use nickel and cadmium metals as chemical reagents. Nichel is the cathode while the cadmium is the anode.
Among the advantages of nickel-cadmium batteries there are the less request for care and ease of damage, the greater durability, calculated in discharged-carica cycles, No damage due to the failure to recharge for a long time, smaller charging time
However, all these advantages make nickel-cadmium batteries are relatively expensive in comparison with those to lead.
Ni-CD batteries have a self-scarning rate certified around 5% on a monthly basis.
Most of them have a thermal insulation system that allows you to stop the charge if the temperature is too high. Sometimes this involves the interruption of the charge if the battery is put in charge immediately after use.
These batteries contain the cadmium which is a heavy and toxic metal and therefore requires a lot of care its disposal. This is one of the factors that most affects the price of these batteries, which often includes a dedicated percentage of the environment protection.

The expert advises

 

The expert advises you to discover the new lithium -ion makita battery with 5.0 Ah which completely recharges in just 45 minutes.
This battery was created to respond to the increasingly frequent requests from the end users, requests that demand greater autonomy, not granting changes to weight or size.
The development of this battery responded satisfactorily to market demands, a battery that has maintained identical dimensions and weights to previous versions of 3.0 Ah and 4.0 Ah. Today we can speak of development and evolution of product, we can touch what the path taken by Makita to always be alongside the final user.

The charging system is still one of the main features that differentiates Makita from all atri; The new 5.0 Ah battery records a total charging time of only 45 ', this result of very strong investments in research and development.
Makita technology performs an active control of the current temperature and the voltage of the individual cells component the battery, thus guaranteeing a 22 -minute charging cycle for the 3.0 Ah version, 36 minutes for the 4.0 ah version e only 45 minutes for the 5.0 ah version

 


Guide to the extension of the life of a rechargeable battery

 

First of all, we advise you to always buy original batteries and equipped with a guarantee. For this reason the online store only sells batteries from reliable and renowned producers such as Makita, Bosch And Leica.
Mainly the issues to be taken into consideration if you also want your battery long lasting are two: the temperature and charge of storage and the safety in use of the product.

Unlike the nickel-metal or nickel-cadmium battery, lithium-ion batteries need a very frequent charge-scarco cycle, we even recommend that you never download them completely or keep them download.
If a Li-ion battery were charged it should be used immediately while for their conservation most manufacturers recommend a charge percentage around 50% and cold temperatures, such as those of a home refrigerator.

As for safety, it must always be kept in mind that the batteries can be easily damaged, both by high temperatures and due to falls. Never ever short The battery, since this practice could lead to fire or out of dangerous exits for both the user and the environment.
Never open the external container of the battery, since it very often contains devices to the safety of the same battery that could, if tampered with, stop the functioning of the same.
