What is a lead acid battery?
Current collectors in lead acid batteries are made of lead, leading to the low-energy density. In addition, lead is prone to corrosion when exposed to the sulfuric acid electrolyte. SLI applications make use of flat-plate grid designs as the current collectors, whereas more advanced batteries use tubular designs.
What happens if you overcharge a lead acid battery?
Due to the production of hydrogen at the positive electrode, lead acid batteries suffer from water loss during overcharge. To deal with this problem, distilled water may be added to the battery as is typically done for flooded lead acid batteries.
Why do lead acid batteries lose water during overcharge?
In addition, the large size of lead sulfate crystals leads to active material disjoining from the plates. Due to the production of hydrogen at the positive electrode, lead acid batteries suffer from water loss during overcharge.
Why should you repair a lead-acid battery?
Effective repair of the battery can maximize the utilization of the battery and reduce the waste of resources. At the same time, when using lead-acid batteries, we should master the correct use methods and skills to avoid failure caused by misoperation.
Do lead-acid batteries fail?
Lead-acid batteries are widely used due to their many advantages and have a high market share. However, the failure of lead-acid batteries is also a hot issue that attracts attention.
How does corrosion affect a lead-acid battery?
Corrosion is one of the most frequent problems that affect lead-acid batteries, particularly around the terminals and connections. Left untreated, corrosion can lead to poor conductivity, increased resistance, and ultimately, battery failure.
