What must be paid attention to when using the battery when loading and unloading and connecting? why
Answer: It is necessary to pay attention to insulation; because the battery leaves the factory with liquid charge, it should prevent the danger of short circuit or electric shock due to improper operation.
What is the danger if the connecting bolts are not tightened?
Answer: A loose connection will cause the resistance at the connection to increase, which will easily cause sparks during charging and discharging. In severe cases, it will cause heat and fire, and an accident will occur.
Why does the battery distort the belly?
Answer: The reasons are as follows:a. Overcharge ① Charger float charging current is too large without timing function ② The charging voltage is too high after the charger parameters drift b, the ambient temperature is too high c. Single cell short circuit d, acid density is too high e. The acid error of the battery cell is too large f. Excessive acid absorption and quantitative deviation of the separator g, the plate oxidation is not the sameh, the pressure of the safety valve is not consistent i. The allocation is not strict j. Shell rupture k. The user privately allocates batteries into groupsIt is concluded that for various reasons, water loss is serious, thermal runaway is caused, and the battery belly is deformed.
How to distinguish true and false gel batteries?
A: Colloidal batteries are recognized internationally by using gel-specific separators (PVC, PE, phenolic resin, etc.) as true colloids, and AGM separators as false colloids are not recognized internationally. The definition of true and false colloids still depends on the amount of silica added. The amount of silica used for colloidal separators is more than 5%, and AGM separators exceeding 1.5 are difficult to add.
What problem does colloid solve?
A: The colloid solves the problem of electrolyte layering. For batteries in which the electrolyte is in a non-gel state, the electrolyte layering is affected by gravity. As a result, the negative electrode plate in the lower part is easily sulfated, and the upper grid is easily corroded. The colloid is added into the battery after high-speed stirring. Due to the thixotropic nature of the colloid, the gel rapidly forms a mesh-like whole.
