How does BP-12/24 protect/desulfate lead acid batteries

Although we know that the main way to prevent the battery from ageing is to prevent the battery from over-discharging, it still happens frequently in practical use. This has previously been considered “irreversible”.
The traditional method to repair a lead acid battery is complex. Generally the process replaces low concentration electrolyte, apply with small current charge then discharge, and repeat the cycle. Then increase the electrolyte concentration. This method is time-consuming, energy intensive, and has limited maintenance and can not be used in sealed batteries.
The other method uses a high density current to charge the battery, therefore the negative electrode produces a high negative voltage, which causes large lead sulphate crystals to produce negative blocking. Although this method can repair the negative electrode vulcanisation. However it also causes the formation of battery water loss and positive electrode softening, seriously affects the battery life.
Now our product has adopted is the composite resonant pulse (CRP) repair method, which can turn irreversible into reversible and basically do no damage to the battery electrode. The resonance frequency of lead sulphate crystals in the battery varies. Based on the battery size and the crystallisation range, we apply pulse current with specific frequency and amplitude. While the the lead sulphate crystals resonant with the applied powerful frequencies, the lead sulphate crystals will be “crushed”, “decomposition” and dissolved in sulphuric acid electrolyte, in order to participate in chemical reactions again.
CRP technology has fully taken into account the inconsistent lead sulphate crystal resonant frequency and resonant frequency of the electrode plate, then selected the optimal frequency of pulse waveform and pulse current intensity. It can “break” and ” decompose” the lead sulphate crystals, and ensure the best repair effect the sulphide battery, which will not damage the electrode plate.
