valve regulated lead acid battery Old SLA Battery Recovery

Any battery will be dead in a few years, but you can give it a 1up.
Everything is not permanent, everything will be done after a period of time.
What you can do with the big bang.
Nothing will disappear, it will become another substance, that is, the theory of atoms.
The lead-acid battery, invented by French physicist Gaston puller in 1859, is the oldest rechargeable battery.
Very low energy though. to-
Weight ratio and low energyto-
Volume ratio, its ability to provide high surge current means that the battery has a relatively large powerto-weight ratio.
These features, along with their low cost, make it attractive to use in cars to provide the high current required by the car to start the motor.
Because they are cheap compared to newer technologies, they lead the way
Even if the surge current is not important and other designs can provide a higher energy density, acid batteries are widely used. Large-format lead-

For these roles, a modified version of the standard unit can be used to increase storage time and reduce maintenance requirements. Gel-
Cells and absorbing glass
Mat batteries are common in these roles, collectively called VRLA (valve-regulated lead-Acid) battery.
In valve-regulated lead-acid batteries (VRLA), most of the hydrogen and oxygen produced in the batteries are regrouped into water.
The leak is small, although some electrolyte will still leak if the composite does not keep up with the evolution of the gas.
Since the VRLA battery does not need (and is not possible) to check the electrolyte level on a regular basis, it is called a maintenance free battery.
However, this is a bit of a misnomer.
The VRLA battery does need maintenance.
VRLA battery will "dry" when electrolyte is lost"
And lose capacity.
This can be detected by regularly measuring the internal resistance, conductivity, or impedance.
Regular tests show if more testing and maintenance is required.
Recently, maintenance procedures have been developed to allow "re-Replenishing Moisture", which can usually recover a large amount of lost capacity.
Okay, now we're going to weaken the dry battery.
You can recover 99% if not more than 5 years.
If it's only 5 + years left and is not used, you can restore it to about 50-75%.
Due to sulfuric acid, the crystal of lead sulfate, when the discharge time is too long, the lead-acid battery loses the ability to accept charging.
They generate electricity through a chemical reaction of double sulfuric acid.
The active materials lead and sulfur dioxide on the panel react with sulfuric acid in the electrolyte to form lead sulfate.
Lead sulfate is first formed in a finely divided amorphous state, which is easily reduced to lead, sulfur dioxide and sulfuric acid when the battery is charged.
When the battery is cycled through a large amount of discharge and charging, some lead sulfate will not be re-formed electrolyte and slowly converted into a stable crystal form and will no longer dissolve when charging.
As a result, not all lead is returned to the battery sheet, and the number of available active materials required for power generation decreases over time.
When the lead-acid battery is not fully charged during normal operation, sulfuric acid will occur.
It hinders charging;
The sulfuric acid precipitation will eventually expand, breaking the plate and damaging the battery.
In the end, so many panel areas do not provide current that the battery capacity is greatly reduced.
In addition, the sulfuric acid part (of lead sulfate) will not be returned to the electrolyte as sulfuric acid.
It is believed that large crystals physically prevent the electrolyte from entering the pores of the plate.
If the battery is fully charged immediately after the discharge cycle, sulfuric acid can be avoided.
The white coating on the board may be visible (in a battery with a transparent housing, or after removing the battery ).
The sulfuric acid battery has a high internal resistance and can only provide a small part of the normal discharge current.
Sulfuric acid will also affect the charging cycle, resulting in longer charging time, lower charging efficiency, incomplete charging and higher battery temperature.
Sulfur removal is the process of reversing the sulfuric acid of leadacid battery.
It is believed that the high current pulse generated between the terminals of the battery can realize the sulfur removal.
Who believes [?
This technique, also known as pulse regulation, can break down the sulfuric acid crystals formed on the panel.
The duration of the pulse must exceed the resonance frequency of the battery.
The short pulse simply inputs the wasted energy into the resistor element of this resonant circuit, without actually entering it into the battery.
Electronic circuits are used to regulate pulses of different widths and frequencies of high current pulses.
These can also be used to automate the process because it takes a long time to completely digest the battery.
Battery charger designed to remove lead
Commercial acid batteries.
If the active material is lost from the plate, or the plate is bent due to excessive temperature or overcharging, the battery will not be able to recover.
Batteries that have not been used for a long time may be the main candidate for clutter.
Self for a long time
The discharge makes the sulfuric acid crystals form and become very large.
Some typical cases where lead-acid batteries are not often used are in use by aircraft, ships (especially sailing boats), old cars and home power systems with battery libraries.
Some charging technologies can help with prevention by regularly discharging and charging, such as balanced charging and cycling.
It is recommended to charge properly according to the instructions of the battery manufacturer.
SLI batteries (start-up, lighting, ignition; i. e.
Car batteries) are most damaged due to the fact that the vehicle is usually not used for a relatively long period of time.
Deep Circulation and power cells are overcharged under regular control, so eventually yield to the corrosion of the positive plate grid rather than sulfuric acid.
Extreme weather can also cause vulcanization in batteries.
The summer heat has increased the amount of sulfate from the battery.
Electronic components that are constantly consumed on the battery will also increase the amount of sulfuric acid.
Keeping the battery in a cool position and keeping it charged helps prevent this.
You can see the lead plates in the picture, they are inside the battery.
I bought it with a 6 v lead acid battery.
When they responded, the supply voltage was lower.
So this shows that I only recycle dry batteries.
We can't collect the broken lead plate.
You can now see that the battery voltage is 0 v.
We will see changes after recovery! 1.

Safe first clean workplace! ! !
In doing so, please use safety gloves and goggles.
Because battery acid can leak, this is important at 2nd.
Sulfuric acid is corrosive, and it will get hot when splashed on the skin.
It can eat your skin in a minute. NOT IN SECONDS! ! !
Pump some water with a syringe.
As the number of your batteries changes.
So, pump water before each battery is full.
Let them sit for a moment and close the lid and hat.
Shake your battery, if you can hear the sound of water, as you hear when you shake your drink, it means there is too much water, so be careful not to overdo it.
You can replace cloves with a Y tube, and it is recommended to use acid for batteries over the age of 5.
Or you can use both methods, but be sure to dry the battery to reduce moisture.
Charge the battery with the right matching charger.
Don't overcharge!
, And can use about 1 v more than the battery voltage.
The battery may heat up.
But this is not a good bad signal. OK!
My battery is recovering very well!
You can use a multimeter or LED, DC motor to determine its recovery.
If your battery is not good, you will have to pump sulfuric acid instead of water again.
If any of these methods don't work for you, it means the panel is done! ! !
