Batteries play an important role in our daily lives, powering the devices that keep us connected and productive.Like the electric bicycle we ride in our daily life, it has a special electric e-bike battery, and Godson Technology is one of the largest electric e-bike battery suppliers. However, sometimes the battery seems to lose its spark and refuses to charge or hold its charge. Is there a way to revive a dead battery?
Let's first understand the cause of battery obsolescence, that is, battery acidification. What is battery sulphation? If the discharge is too low, your battery will reach a point where it can no longer be restored and needs to be replaced. This happens due to a process called sulfation. When a lead-acid battery is discharged, small sulfate crystals made of lead and sulfur form on the battery plate. This is a natural part of the discharge process, which goes into reverse when the battery is charged. If the battery is discharged for too long, these soft deposits will become hard, stable crystals, blocking the current flow of the battery, and eventually lead to the battery's demise. Can battery sulphation be reversed? If sulfation is detected early enough, it can be reversed in liquid-rich lead-acid batteries. To do this, you can overcharge a fully charged battery for about 24 hours using a regulating current of around 200mA (mA). This increases the terminal voltage of each cell to 2.50 to 2.66 volts, which helps dissolve the sulfate crystals. If your battery is too low to try this, you can use a battery charger designed to recover severely discharged batteries. These devices work by sending pulses to the battery terminals to reverse sulphation. If you are looking for a charger that can restore sulfated batteries, we recommend you use the X2Power 7.5-amp charger, which has a recovery mode for deeply discharged or sulfated batteries. Keep in mind that sulfation is particularly difficult to reverse in AGM and sheet pure lead AGM batteries, as they do not respond well to low current charging.
One way to do this is to use baking soda and aspirin
Other popular tricks include adding baking soda to revive a dead battery. Baking soda mixed with water is commonly used to clean battery tops and battery terminals because it neutralizes sulfuric acid and acidic corrosion products. Adding baking soda to the battery neutralizes sulfuric acid in the electrolyte into sodium sulfate, which cannot be discharged into lead sulfate in a normal discharge reaction. This also permanently reduces the capacity of the battery, which is likely already low.
Adding aspirin to a battery is another hack, often seen in videos that claim to restore depleted batteries. Weimer says aspirin is acetylsalicylic acid, which eventually breaks down into acetic acid. Acetic acid can corrode the positive lead dioxide plate in the battery and cause permanent damage to it, resulting in shortened battery life. This may show a small temporary increase in capacity, but it will soon drain the battery power.
Pulse charging
If your battery has been sulfated, resulting in low charge and difficulty charging to full capacity, it can sometimes be restored using the appropriate pulse charging technology. However, various devices sold for this purpose use a myriad of pulse charging technologies. These technologies include DC (direct current) pulses using a variety of voltages and currents, and AC (alternating current) pulses with a variety of AC frequencies. Having said that, by testing some very complex and very expensive pulse chargers, they seem to recover sulfuric acid batteries much faster than traditional methods. Most pulse chargers use an external power source (wall AC) to power the device. However, some use battery voltage to power the charging pulse. If connected for a long time without a separate charger, this can drain the battery.
Ultimately, the best advice for possible recovery of sulphuric acid batteries is to save money and try to use a long, slow charge. If your battery charger has a repair or balanced charging mode, then this may be your best choice. Use a balanced charging mode for deep-cycle lead-acid batteries regularly, about once a month, to extend the life of the battery, and regular balanced charging can prevent sulfation and delamination by balancing individual batteries and properly mixing electrolytes. In addition, a long period of slow charging can help restore the already sulfated battery, making it last a little longer. If your charger does not have a balanced charging mode, simply wait for the charger to finish charging normally, then unplug the AC power and reconnect it to restart. The charger should continue charging for 1-3 hours. If the battery wears out due to poor maintenance, excessive deep cycling, overcharging or excessive deep discharge; I'm afraid it's impossible to recover.
