An Equalize charge (equalizing) should be used on flooded batteries when specific gravity readings vary +/-.015 from cell to cell on a fully charged battery. Equalizing is an "over voltage - overcharge" performed on flooded lead-acid batteries after they have been fully charged to stimulate gassing and bubbling (essentially mixing) of the
Equalizing charge refers to a deliberate overcharging process applied to lead-acid batteries to balance the voltage across all cells and prevent sulfation. This maintenance procedure enhances battery performance and longevity by ensuring that each cell reaches a similar state of charge, thus optimizing overall efficiency. What is Equalizing Charge?
If you have a lead-acid battery, it''s important to keep it healthy by equalizing it on a regular basis. Equalization is the process of bringing all the cells in the battery to the same state of charge, which is accomplished by
Equalizing lead acid batteries is a process designed to de-sulphate the battery plates by carrying out a controlled overcharge. Battery plates tend to acquire a sulphate coating over time which then hinders the chemical action between the electrolyte and the plate. By equalizing the battery in this controlled overcharge the outer layer of the
The sulphation, desulphation and restoration of lead acid based batteries is widely misunderstood. This presentation describes and explains: – The normal lead based battery charging and discharging cycle – How and why batteries experience sulphation – Normal and harmful sulphation – Why damaging sulphation occurs
In the realm of battery maintenance, equalizing charge is a crucial procedure, particularly for flooded lead-acid batteries. This specific maintenance technique ensures optimal performance and extends the lifespan of batteries by addressing common issues such as
The free sulfur ion crystals build up on the battery''s lead-acid plates. Without intervention, the crystals will grow, harden, and completely cover the lead plates. An equalization charge overcharges the battery at a low, controlled rate. The process slightly heats the electrolyte, forces current through the plates, and removes light
A topic we receive regular questions about is equalizing charges – or the deliberate overcharging of a battery. Since there''s a lot of confusion about what it is, how it affects your battery type, how to do it, and when it should be done, we''ve compiled the
Equalizing charge is overcharging a flooded lead acid battery to counter sulfation and stratification. Sulfation is the process of accumulation of sulfate crystals at the lead plates when the battery is constantly undercharged. This has been discussed in detail in a previous post (Battery Sulfation). Stratification is accumulation of acid at the bottom of theRead More
An equalizing charge is needed because lead-acid batteries have sulfation issues that prevent proper charging. Sulfation takes place because small sulfate crystals form
To equalize a flooded lead-acid battery, first fully charge the battery, then increase voltage to initiate the equalization charge, which causes controlled overcharging.
Manufacturers recommend equalizing the battery once every six months if the battery is not used much. Or, equalizing charge should be applied after 20 cycles. If you are a methodical person you can also take specific gravity measurements using hydrometer and decide accordingly. You can learn all about taking specific gravity measurements in
There, we apply an external electrical current to convert the lead sulfate and water back into lead dioxide, sponge lead, and sulfuric acid. What are the Three Main Stages of Charging a Lead Acid Battery? Bulk, Absorption, and Float are the 3 main charging stages of a typical lead acid battery. In addition, there could be one more stage called
Lead-acid batteries balance their charge using a method called "Equalization." This process intentionally over-charges the cells with the highest charge in the series string. This action helps lower-charged cells receive adequate charge. As a result, it ensures optimal cell performance and extends battery life.
A true equalization should NEVER be done automatically, as the high charge voltages could easily overheat and damage the battery, and/or boil the water over the top. There is also no reason to do a regular equalizing cycle if the SG stays the same across cells (it should). Doing so would be overcharging and damaging to the battery.
Manufacturers recommend equalizing the battery once every six months if the battery is not used much. Or, equalizing charge should be applied after 20 cycles. If you are a methodical person
Equalization is a process of controlled battery over-charging. It is used as a routine maintenance activity and a remedial activity for flooded lead acid batteries. It is part of the multi-stage charging process. Lead acid batteries suffer from ''sulfation''. This happens when the sulfuric acid inside the battery cells form tiny crystals on the lead Read More

Implementing regular equalizing charges as part of your battery maintenance routine can significantly extend the lifespan and improve the overall performance of your flooded lead acid batteries. By adhering to these best practices, you can maximize the efficiency and durability of your batteries for years to come.
The two types of lead-acid batteries that use an acidic electrolyte are wet cell and sealed. Wet cell use liquid electrolyte; sealed batteries use either a gel or liquid electrolyte absorbed into fibreglass material. Terminals. The terminals are the pure lead at the negative side and the PbO2 on the positive side both constructed as ''plates''. With acid electrolyte and lead
For a typical lead-acid battery, the float charging current on a fully charged battery should be approximately 1 milliamp (mA) per Ah at 77ºF (25ºC). Any current that is greater than 3 mA per Ah should be investigated. At a recent International Battery Conference (BATTCON®), a panel of experts, when asked what they considered were the three most important things to monitor on

Regular equalization charging contributes to the overall health of lead-acid batteries. By preventing sulfation and balancing cell voltages, equalization charging can significantly enhance the battery''s lifetime. This proactive maintenance measure ensures that the battery operates at peak efficiency throughout its service life.
Equalization is specific to flooded lead-acid batteries and is not recommended for gel or lithium batteries due to their different chemistry and the potential for damage. Each battery type has specific voltage guidelines for charging and maintenance. What is the duration required to safely equalize a lead-acid battery?
Equalization charge is vital as it maintains the health and extends the life of your flooded lead acid battery. By periodically applying an equalizing charge, you evenly distribute the electrolyte concentration and bring each cell’s voltage to the same level, ensuring your battery operates efficiently.
Each battery type has specific voltage guidelines for charging and maintenance. What is the duration required to safely equalize a lead-acid battery? The duration of equalization can vary but typically ranges from one to several hours. It’s essential to monitor the process as overcharging can occur if equalization is left unchecked for too long.
