A lead-acid battery is a electrical storage device that uses a reversible chemical reaction to store energy. A lead-acid battery is composed of a series of plates immerse in a solution of sulfuric acid. When the battery is discharged (when it is subjected to an electrical load), acid from the elecrolyte combines with the active plate material. When a battery is recharged, the opposite occurs: the lead sulfate reverts back to active material, and the electrolyte becomes more acidic with a higher specific gravity.
During discharge, the lead dioxide (positive plate) and lead (negative plate) react with the electrolyte of sulfuric acid to create lead sulfate, water and energy. Many new competitive cell chemistries are being developed to meet the requirements of the auto industry for EV and HEV applications.
Even after 140 years since its invention, improvements are still being made to the lead acid battery and despite its shortcomings and the competition from newer cell chemistries the lead acid battery still retains the lion's share of the high power battery market.

With all the alternative sources of energy being explored and implemented; we are seeing a rising trend in demand of Lead acid batteries.
It uses a combination of lead plates or grids and an electrolyte consisting of a diluted sulphuric acid to convert electrical energy into potential chemical energy and back again. Each plate consists of a grid upon which is attached the active material (lead dioxide on the negative plates, pure lead on the positive plates.) All of the negative plates are connected together, as are all of the positive plates. Packaging should be the same as what is found in a retail store, unless the item is handmade or was packaged by the manufacturer in non-retail packaging, such as an unprinted box or plastic bag.

Import charges previously quoted are subject to change if you increase you maximum bid amount.
However, these batteries have a high cost and you will need to spend quite some money to replace them (average life of commercially available deep cycle batteries is 1.5-2 years) when they die out on you. The electrolyte of lead-acid batteries is hazardous to your health and may produce burns and other permanent damage if you come into contact with it. The electrolyte become less acidic in the process, and the specific gravity of the solution drops. If you reside in an EU member state besides UK, import VAT on this purchase is not recoverable.
This is where we come in with our guide on how to rebuild a battery from your dead battery.
The battery is normally mounted on racks and is continuously charged except for intermittent discharging intervals of varying times and power.
Alright, so how do you build a battery from an existing dead battery and more importantly why does the battery die?
In the next few paragraphs the types of plates and grid alloys for the lead acid and alkaline (Ni­Cad), the electrolyte properties, battery charging, battery safety and finally battery maintenance will be covered.
Lead-acid battery constructionFor the lead acid battery, the positive plates a vailable are: the pasted (F aure) plate which comprises of a latticework metallic grid with the openings filled with lead oxide paste. The grid may be made up of lead antimony or lead calcium, the properties of which will be given later .The second type is the multitubular plates, which use porous plates to contain the lead o xide. The grid (lead antimony) is basically a row of spines extending from the top bar to the bottom cap bar.
This results in a decrease in battery’s capacity and consequently failure.You can recover the oxides (covered later in the article) from the positive plates that have fallen victim to the anodic corrosion and use it to make paste for the new plates.
The positive plate consists of a grid (lead antimony) of large area with thin layers of lead oxide. So; we will be using the negative plates to make a new cell with the paste that comes from oxides. This means that you’ll be building a 3 cell battery from 6 cell battery.Advertisement Now to get to the job’ remove the positive plates and have them placed in a metal container, which can take some beating. The grid of alloys, antimony or calcium, serves both purposes gives physical support and strength to the soft lead and acts as an electric conductor.The grid achieves and retains a physical shape and conducts the current to all parts of the material. Use a hammer or anything that is hard that can transfer impact to turn these plates into powder.

Pasted plates with lead calcium alloy grids are used in sealed maintenance free lead acid cells due to the fact that this type does not require watering during its life time.Lead antimony is preferred for installations where elevated temperature and frequent cycling is encountered. Once you have crushed the plates, remove small pieces of lead and grid from the mixture by sieving the contents. Lead calcium is also used for installations requiring longer intervals between maintenance watering. Mix this powder with sulfuric acid and water to form a paste which will be placed into the plate’s grid structure and cured. Mix the fiberglass and glass fibers that have been recovered from the separators to strengthen the paste.
Once the paste has been applied you will need to cure the plates, which is usually done at 30 degree Celsius in high humidity for about 48 hours.
At home, just put them in a pot that is filled with water into the oven and keep an eye on the water level. First off, cut the top off the battery and leave about 5 mm of plastic around the terminals. Now you need to cut the interconnection between the cells and remove the cells from the case.Now you need to perform the process of forming in which, active materials are formed on the new plates. The idea is to pass electric current and then reverse the direction and continue the same procedure for about say 30 times. If you continue indefinitely you’ll destroy the plate.Let’s make some electrolyte, shall we?
Alternatively, you can buy a sulphuric acid solution with 1250 sp gravity from a battery shop to use as a battery electrolyte.
Now all that is left is placing the plates back into the case, sealing the top and filling it with electrolyte. If you still decide to do it, make sure to work very safe as the lead-acid is very dangerous. Required fields are marked *CommentName * Email * Website Notify me of follow-up comments by email.
