What Are The Misconceptions About Batteries

No initial charging
The first charging of a battery is crucial to its overall performance and lifespan. If the initial charging is inadequate, the battery's charge capacity will be low and its lifespan will be shortened. On the other hand, overcharging can lead to good electrical performance but a shortened lifespan. Therefore, it's essential to charge new batteries correctly for the first time. Dry charged lead-acid batteries can be used within two years of their storage period by simply adding electrolyte with the appropriate density and waiting for 15 minutes before charging. However, if the storage period exceeds two years, supplementary charging is necessary to increase its charge capacity and should be charged for 5-8 hours before reuse due to partial oxidation on the electrode plate.

 

No supplementary charging
It is crucial for drivers to remember to fully recharge their in use batteries. Neglecting to do so can lead to electrode plate vulcanization, which occurs when the battery is not fully charged in the vehicle. This imbalance between electricity charged and discharged during use can cause long-term depletion, resulting in chronic sulfurization. Over time, this will reduce the battery's charge capacity and lifespan, making it weak to start. To prevent this, regular battery recharging is necessary in order to restore active substances on the battery plates, reduce sulfurization, and improve charge capacity. By following this practice, drivers can extend the lifespan of their batteries and ensure reliable vehicle function.

 

Battery overcharging
Frequently, batteries undergo overcharging, leading to the electrolyte boiling for an extended period, which causes damage to the surface particles of the active substance. Additionally, overcharging can result in the excessive oxidation of the grid frame, causing the active substance to detach from the grid frame and loosen.

 

Reverse polarity during charging
The negative plate of a battery is designed with different materials from the positive plate. To prevent shrinkage and oxidation, various substances like barium sulfate, humic acid, carbon black, and rosin are added to the negative plate. It's worth noting that the number of negative plates is always one more than the positive plates in each single cell battery. Additionally, the negative plate is slightly thinner compared to the positive plate. It is crucial to pay attention to polarity during charging to avoid charging the battery backwards. Charging in reverse can lead to coarse-grained PbSO4 formation on both positive and negative electrodes, resulting in insufficient battery charge capacity and improper functionality. In the worst-case scenario, the battery may even become scrap. Therefore, reversing the polarity during charging should be strictly avoided.
