Can I charge a charged battery? Can I charge a maintenance-free battery?

Without a drive and an additional source of energy, none of the modern mechanisms, gadgets, radiotelephones will work. In all types of vehicles - in cars, diesel locomotives, aircraft - they serve to start engines and support the functions of electrical appliances. Deer, of course, is better, but beyond the tundra they can not leave ...

Structure and principle of battery operation

Can I charge the car battery? Traditional energy storage devices consist of several compartments (cans), united by one strong plastic casing. In each bank, filled with dilute sulfuric acid (electrolyte), there are lead plates. All departments are sequentially connected to each other in a single system. As a result of the interaction of metal and electrolyte, electricity is released. Then everything is simple:

• Current flows through the wires to the starter;
• Then to the spark plugs;
• Petrol cylinders break out in the cylinders;
• The engine starts;
• The generator begins to generate electricity, which accumulates in the electrolyte.

Ideally, all this should happen, but in some cases the car can not be started - the battery "sat down".

How to fix the situation

The cause of battery discharge may be a change in the density of the electrolyte or a general drop in capacity. Sometimes, especially after a long period of inactivity, the lead plates inside the cans fall apart. Can I charge a charged battery? If you want to reduce the life of the device, you can do it all the time. If you approach the process responsibly, it is better to avoid such situations, since when components are overheated, there is a strong gas evolution. The amount of liquid decreases, the proportions are violated, the reaction is wrong, the performance of the battery decreases.

If, however, the level and density of the electrolyte are controlled, compliance with the operating modes of the mechanism during its inactivity, it will not be necessary to answer the question "Is it possible?". Charging a charged battery is only allowed on the phone or laptop. And then within an hour and a half after the readings of the occupancy on the indicator.

Can I charge lithium batteries and how to do it correctly?

For effective operation of mobile electronic devices, powerful autonomous power supplies are now required. Careful use and proper recharging will extend the life of lithium-ion storage. The rules are as follows:

• Do not allow the time of an "empty battery";
• Once in 3-4 months you need to do a preventive full zeroing;
• Store an unused source with a value of 35-50% power;
• For recharging use special devices;
• Do not keep in the sun;
• Alternate cycles of full and partial filling of the battery.

These measures will extend the lifetime of lithium-ion energy storage.

On locomotives and motor ships

In industry, in rail transport and in the shipping industry, larger and more powerful electrical systems can not be avoided. Alkaline and acid batteries work on the same principle, but differ in size. Can I charge a charged battery of such modifications? The main recommendations are true for all kinds of batteries. Regardless of the appearance, the materials of the shell and the composition of the electrolytic filler, the schemes of the occurring chemical reactions are identical.

The main advantages include the ability to work and store at very low temperatures, fast speed of power.

Can I charge an alkaline battery? Of course, the answer is yes. It is important to comply with the regime and avoid overheating, at which the internal pressure increases, oxygen gas is released and the current intensity coefficient decreases.

Existing ways to revive the "heart" of the mechanism

Can I charge the gel battery under a slow voltage? Let's name the types and methods used:

1. "Slow" - the safest, but the longest is considered an impact discharge current of 0.1-0.2 C. By time, it takes 8 to 15 hours.
2. "Fast" - a stronger current (1/3 C), 3-5 hours.
3. "Delta V" or "Accelerated" - in which the initial voltage supply is equal to the capacity of the drive. For an hour and a half, the battery is fully charged. A fairly risky method that can lead to overheating or destruction of the battery.
4. "Reversible" is most effective for alkaline devices with a "memory effect". The process occurs with an alternation of short discharge periods and long charge periods.

In fact, for each type of battery, there is a special device that supplies the currents of the required force and provides a suitable impulse and voltage. Digital indicators are built in to the digital equipment, automatically disconnecting the flow of electricity when the device has a nominal capacity. For power sources used in cars, locomotives, aircraft and other vehicles, there are special devices to restore their performance.

Importance of quantity and quality of electrolyte

A frequent problem with motorists is the battery failure due to a chemical reaction in the banks. Why is this happening? There are only two reasons, and they are associated with a violation of the composition or amount of electrolyte:

• The change in density due to the boiling off of water with frequent overheating;
• Leakage of liquid in case of damage to the hull or strong slopes of the vehicle.

In improperly operated devices, they can scatter the plates themselves, break contact between the banks or there is a shortage.

The density of the electrolyte is regulated by adding distilled water to each compartment. By adding a catholytic liquid of the desired composition, the battery capacity of the whole case is restored.

Features of the newest battery

The system of lead-calcium energy sources is designed in such a way that when operating in them to minimum values, the process of gas evolution and, correspondingly, loss of water is reduced. This allows you to extend the shelf life of the electrolyte to 15-25 months. One of the important operating conditions is the adjustment of the output voltage of the generator to an indication of 14.4 V.

Can I charge a maintenance-free battery? The shell of the device does not have lids and holes for pouring liquids, it is hermetically sealed. The voltage level is indicated by an indicator located inside of one of the cans. By changes in its color determine the state of the battery:

• The peephole glows green - it means everything is in order;
• The color darkens or turns black - it's time to increase the current level;
• The indicator has become yellow or colorless - the device has become completely worthless, it remains only to throw it away.

It becomes clear that any device requires careful and careful handling. And the question "can I charge a maintenance-free battery" with the answer "I need", and on time. Otherwise, you have to spend money on the purchase of a new device.

Differences of gel batteries from liquid

The main advantage of a modified acid device is a dense electrolyte enveloping the plates inside the cans. At any incline of the vehicle (except for the inverts), such a battery continues to work. The body is damaged, there was a crack from the impact - it does not matter, you can just seal a hole. The state and quantity of such catholyte does not affect this, since a thick substance does not flow. This feature is a great advantage in the process of using batteries under extreme conditions. Gel batteries are equipped with military aircraft, scooters, modern cars.

Despite the slow current output, the battery is required from time to time to be recharged by means of a special device. Can I charge the gel battery? The incoming voltage must have a valid value. Exceeding the threshold readings is fraught with the peeling of the electrolyte substance from the lead plates and the failure of the apparatus. With proper operation and recharge conditions, the battery is capable of withstanding up to 1000 cycles, lasting up to 10 years.

How can one act

1. Connect the charger contacts to opposite terminals of the battery.
2. First, insert the memory into the network, and only then connect it to the battery.
3. At the end of the process, first disconnect the positive terminal.
4. Do not pay attention to indicators of devices and indicators.

Can I charge a charged battery? It seems that after reading all the recommendations, this question will become redundant, since the answer itself suggests itself.
