What is a battery ? How does it work?

A battery is a device which stores electrical energy as a chemical energy and gives it out as electrical energy again when needed.

The task of the battery is, first of all, to supply electrical current to start the motor for enabling it to operate in the first moment, send electrical current which shall be used when the motor of the vehicle does not function, to the receivers and balance voltage and amperage in the electrical system while the motor is functioning and, in this way, prevent the receivers to be damaged since the voltage that shall be produced by the alternator may sometimes increase in high circuits.

In that case the battery prevents the increase of the extreme voltage by taking over part of the current produced by the alternator. The 12 volt battery used in the gasoline engines is formed by 6 two volt cells which are serially connected to each other.

Generally there are five pieces of positively and six pieces of negatively loaded plaque which are again serially connected to each other inside each element. These plaques are formed by plastering and firing active substances on the lead-antimone alloyed grills. Positive plaques contain lead dioxide as active substance . Negative plaques contain pure lead as the active substance . Seperators which insulate the plaques are placed between the plaques for the purpose of avoiding short circuits . . Seperators are made of substances with very small pores so that the chemical reaction between the plaques are not hindered. Electrolyte which is a mixture of sulphuric acid and pure wlater is put in the battery . The elements are serially connected through lead bridges.

How is connection from battery to battery is made?

Take care that the battery that you shall use for connection from battery to battery (Jump-start) has the same amper.
Close the motor and everything that is possible to expend electricity .
First of all connect the red end of the cable to the (-) terminal of the discharged battery and then connect the other end of the cable to the terminal of the battery which is fully charged.

Thereafter connect the black end of the cable to the (-) terminal of the fully charged battery and connect the other end of the cable to any metal part in the body shell of the vehicle of which battery has been discharged.
Take care that the cables don’t contact the moving or hot spots like exhaust and propeller.
Start operating first the vehicle with full-battery and then the vehicle with empty battery .
You may dismantle the cables beginning from the vehicle with empty battery after the vehicles have started operating.

What are the battery types, what does fully-closed or dry battery mean?

Batteries are classified into different types according to the different metal types used like lead-acid, nickel- cadmium and nickel-iron.
The type of battery which is the most frequently used one today is the lead-acid accumulators.

And these batteries are mainly divided into two groups as dry and diluted types.

The types of diluted batteries which are most frequently used are the classical type automoobile batteries which we also call Starter or SLI (This word is an acronym formed by the english initials of the starting, lighting and firing functions ). Automobile batteries are divided into two groups as the fully closed ones and the ones of which plugs may be opened . The inner structure of both of these batteries are the same .
In other words both of them are the classical type lead-acid batteries The difference of the closed batteries is the inability of the plugs to open.
It would be more suitable to install these batteries in the vehicles which have a good voltage mechanism since it is impossible to add water to these batteries .
Moreover, stationary and traction (Forklift) batteries are also included in the scope of diluted products although their inner structure and fields of use are different .
Inner structures abd technologies of dry,i.e. VRLA batteries are different . The meaning of the definition of VRLA in turkish is lead-acid batteries with adjusted valve. These batteries are divided into two groups according to their inner structures.
AGM batteries (i.e the batteries of which electrolyte has been let absorbed by the seperators) and VRLA batteries with gel. The main characteristic of these batteries is the non existence of acid overflow or leakage. Gas emissions are at a minimum level . For that reason it is very secure and their shelf lives are much more longer. Besides they are more resistant against vibration in comparison to the diluted batteries. Their shipment and transport is trouble-free. Stationary plastic, UPS’s, boats and power stations are among their fields of use.

What does UPS battery mean?
UPS is an abbreviation of the initials of the expression uninterrupted power supply. And UPS battery is the battery of these sources of uninterrupted power supply. The batteries of the sources of uninterrupted power supply steps in when there is a electricity cut and continue to be a energy store until the electricity is available again. These batteries are VRLA type batteries which we call dry batteries as we have said above and emit minimum amount of gas.

What are the reasons of the discharging of the product , which you have newly bought,in a short time ?
The possible causes of the discharging of MUTLU battery that you have bought.
Negative environmental and preservation conditions , high temperature, humidity etc.
The leakage currents in the vehicle (currents which are pulled high from the envisaged short circuits), open lamps
Short circuits in other electrical devices and equipment
The disharmony of the vehicle and battery , selection of small battery , the additional equipment in the vehicle (sound, light, computer systems , cooling systems )
The undercharging of the alternator (charging generator)

Does the battery freeze?
Yes batteries my freeze.
The freezing heat of the fully charged battery is between -50 C and -70 C. For that reason a charged battery does not freeze under normal conditions .
However the discharged batteries may freeze even at the level of around 0 C and 10 C depending on the level of discharge
Care must be taken for ensuring that the batteries are charged especially in cold seasons .
Are the batteries detrimental to the environment ? What portion of a battery is recovarable?
Accumulators is composed of lead, sulphuric acid solution and polyprolen box .
For that reason batteries become wastes that pose a risk on and are dangerous to the environment when they are no more usable.
However the poliprolen box and lead components of the batteries may be recovered 100 % by means of an effective recycling system . On the other hand it is also possible to recycle sulphuric acid but it is generally preferred to neutralize it.
There is an effective system of recycling for batteries ; deliver your old battery to the seller while buying your new battery .

How must batteries be charged?
See service instructions

How do the weather conditions influence the batteries?
The effects of weather conditions on the battery

1. From the point of view of stock keeping and preservation
Stocks must be kept in open areas. Dust and rains spontaneously increases the dsicharges in case of stock keeping in open air.
Socks must be kept in a as dry and cool place as possible . The discharge rates of the batteries increases or decreases parallel to the temperature . Generally the loss is spontaneously doubled at each increase of 10 C . For that reason stock keeping in the intervals of 10-16 C is much more healthier than stock-keeping in the interval 25-30 C.
2. While working on the vehicle
The starting power of the battery increases in hot weather but the corrosion in the battery also increases parallel to that. For that reason the batteries used in hot climates have a shorter economic life.
The startng power of batteries decreases in cold weather . Additionally the value of startig and accelerating of the vehicle’s motor also increases . Consequently the starting power of the batteries becomes important in cold weather conditions. There is the risk of freezing for the fluid inside the battery (electrolyte). A fully charged battery freezes at only 70 C while a battery in the process of charging may freeze at even -5 C depending on the level of charging. For that reason it is important to keep the battery charged in collection weather conditions
