Embodiment Construction

[0034] The specific embodiment of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0035] The reasons for the reduction of battery capacity can be summarized as follows (without considering the physical damage of the battery): 1. The lead sulfate crystal is too large; 2. The sponge hole of the electrode plate is blocked; 3. The charging temperature is too high; 4. The electrolyte is missing.

[0036]Based on the above situation, the present invention discloses an effective method for restoring a storage battery by combining repair fluid, ultrasonic cleaning and / or pulse charging.

[0037] The recovery method of lead-acid storage battery of the present invention, comprises the following steps:

[0038] Step S1: Check and make sure that the lead-acid battery unit is repairable. Whether the lead-acid battery unit can be repaired can be determined by visual observation and / or instrument inspection. In appearance, the...

Abstract

The invention discloses a recovery method of a lead-acid storage battery. The recovery method comprises the following steps of S1, detecting and determining that a lead-acid storage battery unit can be recovered; S2, adding a recovery liquid dissolved with sulfate into an electrolyte of the lead-acid storage unit; and S3, processing the lead-acid storage battery unit by employing a frequency-variable ultrasonic cleaning mode and/or a frequency-variable pulse current charging mode. By combining the recovery liquid and frequency-variable cleaning and/or frequency-variable pulse current charging,the battery capacity can be safely recovered by 95% or above for a long term by the lead-acid storage battery.

Description

technical field [0001] The invention relates to the field of lead-acid batteries, and more specifically, to a recovery method for lead-acid batteries. Background technique [0002] As we all know, when the lead-acid battery is discharged, the internal resistance increases, resulting in a decrease in the voltage and current supplied to the outside. When charging, the internal resistance decreases. Therefore, the internal resistance becomes one of the factors that characterize the capacity of the battery. [0003] The lead-acid battery needs to be charged according to certain rules to reach the capacity of the battery when it leaves the factory. However, the use of the battery cannot be fully implemented according to the factory standard. For example, the discharge current and time exceed the factory standard, or the charging process does not follow the manufacturer’s regulations. All can cause the service life of the battery to not reach the original service life, generally o...
