Do lead acid batteries have a memory effect?

Lead-acid batteries have no memory effect. Although lead-acid batteries can also have capacity decay if they are not used properly, it is sulfidation, not memory effect. And the memory effect and vulcanization are not the same way to deal with it.

The response to the memory effect is to drain the battery with regular deep discharges, while the response to vulcanization is to try to fully charge it every time.

Lead-acid batteries have developed into lead-acid maintenance-free batteries and gel maintenance-free batteries, and there is no need to add electrolyte or distilled water in the use of lead-acid batteries. It is mainly used to produce oxygen at the positive electrode, which can be absorbed at the negative electrode to achieve oxygen circulation, which can prevent the reduction of moisture. When the discharge is carried out, the concentration of the sulfuric acid solution will continue to decrease, and when the density of the solution decreases to , it should be stopped for charging.

Unlike other secondary batteries, lead-acid batteries have no memory effect, which means that lead-acid batteries do not need to be discharged before charging. Theoretically, all lead-acid batteries can be recharged anytime and anywhere after they have been replaced.

However, due to the limitation of the number of charging and discharging times of lead-acid batteries, it is also necessary to charge the electric vehicle battery at the most appropriate time, so as to maximize the service life of the electric vehicle battery. Generally speaking, the new battery of the newly replaced electric vehicle, due to the impact of its own self-discharge, generally only has about 70% of the power left from the factory to the user's car. For electric vehicles, users can use it up to 30% and then charge it, so the charging effect is optimal.

Lithium batteries have no memory effect.

Battery memory effect refers to the phenomenon that if the battery is a nickel-cadmium battery, it is easy to leave traces in the battery and reduce the battery capacity if it is not completely charged and discharged for a long time.

The battery memory effect means that the battery seems to remember the user's daily charging and discharging amplitude and mode, and it is difficult to change this mode over time, and it can no longer be charged or discharged by a large amount. Lithium-ion batteries do not have this effect.

The electrode is mainly made of lead and its oxide, and the electrolyte is a kind of battery with sulfuric acid solution. English: lead-acid battery.

In the discharge state, the main component of the positive electrode is lead dioxide, and the main component of the negative electrode is lead. In the charging state, the main components of the positive and negative electrodes are lead sulfate. It is divided into exhaust batteries and maintenance-free lead-acid batteries. X0D X0A battery is mainly composed of tubular positive plate, negative plate, electrolyte, separator, battery slot, battery cover, pole, liquid injection cover, etc.

The electrodes of the vented battery are composed of lead and lead oxides, and the electrolyte is an aqueous solution of sulfuric acid. The main advantages are stable voltage and low price; The disadvantages are low specific energy (i.e. energy stored per kilogram of battery), short service life and frequent routine maintenance. The life of the old ordinary battery is generally about 2 years, and the height of the electrolyte needs to be checked regularly and distilled water is added.

However, with the development of technology, the life of lead-acid batteries has become longer and the maintenance is simpler.
