Free QuoteTo recover a lead acid battery, charge it for around 10 to 12 hours. Then, measure the terminal of the battery. After that, check the voltage of each cell and identify any cells with a voltage lower than 2 volts.
In this paper, a new method of charging and repairing lead-acid batteries is proposed. Firstly, small pulse current is used to activate and protect the batteries in the initial stage; when the current approaches the optimal current curve, the phase constant current charging is used instead, when the voltage is low.
One of the most common reasons a lead acid battery shows 0V is sulfation. This happens because, inside a lead acid battery, there are lead plates that are coated with lead dioxide and are separated by a porous separator. When the battery is in use, the lead dioxide reacts with sulfuric acid and produces lead sulfate and hydrogen ions.
Nevertheless, it should be clearly understood that wet (filled) lead acid battery is “a live” product. Whether it is in storage or in service, it has a finite life. All batteries once filled will slowly self discharge. The higher the storage temperature and humidity of the storage area, the greater the rate of self discharge.
Yuasa lead-acid batteries are built to the highest standards. They are manufactured, in most cases to correspond with or exceed the vehicle manufacturer's requirements and specifications. Nevertheless, it should be clearly understood that wet (filled) lead acid battery is “a live” product.
To identify the bad cells in a lead acid battery, follow these steps: Charge the battery for at least 12 hours and then allow it to rest for 10 minutes. Open the battery caps and fill each compartment with water to within optimum levels. Measure the terminal voltage of the battery.
