How to charge a battery properly

How to charge a battery properly, in theory, the smaller the charge current, the better. Because the current is very small, the smaller the crystal, the more fully the reaction, the more electricity can be stored. Moreover, the current is small, the battery gives off heat is small, the plate is not easy to deform, the effective material of the plate will not fall off. 10 hours to charge, 100 batteries, 10 hours to charge, 10 currents. , The charging time is slightly higher than the “Battery capacity/charging current”. If conditions permit, without time limit, charging current can be reduced to below 10a. The special intelligent charger uses the attenuating current to charge, that is, charging at a higher current (10 hours charging rate) at the beginning of charging. As the battery voltage increases, the charging current decreases automatically, until the voltage reaches about 13V, automatic power cut. A better way to charge is a floating charge, which means the battery will be permanently charged, with a charge current of 1-2a.The first charge of a battery is called the first charge. The first charge has a great influence on the service life and charging capacity of the battery. If the battery is undercharged, its charge capacity is low and its life is short. If the battery is overcharged, its electrical performance is good but its life is shortened, so be careful when the new battery is first charged. For Dry charge Lead acid battery, according to the instruction manual, if the battery needs to be used during the storage period of two years, the battery can be used without charge as long as the specified density electrolyte is used for 15 minutes. However, if the storage period is longer than two years, due to some oxidation plate has film, in order to increase its charging capacity, should be charged before use, use after charging 5 hours to 8 hours. Not Charging (1) some drivers often neglect to charge the car battery while in use. Because the battery is not fully charged in the car, it is easy to vulcanize the plate. At the same time, the amount of charge and discharge in use is unbalanced. If the discharge is greater than the charge, the battery will be in a state of power loss for a long time, the battery plate will be slowly vulcanized. (2) this chronic curing will reduce the charge capacity of the battery until the starting power is weakened, greatly shortening the battery life. In order to reduce the active substance on the plate in time, reduce the vulcanization of the plate, increase the charge capacity of the battery, prolong the service life of the battery, the battery in use should be recharged regularly.When the battery overcharges, the battery often overcharges, even if the charging current is not large, but the electrolyte long time “Boiling”, in addition to the surface of the active substances in small particles easy to fall off, but also cause excessive oxidation grid, leading to the active substances fall off grid. In addition to the active substance, barium sulfate, humic acid, carbon black and rosin are added to prevent the contraction and oxidation of the negative plate. In addition, the number of negative plates is always one more than the number of positive plates, and the negative plate is slightly thinner than the positive plate. (2) when the battery is first charged or recharged, if the polarity of the battery is not paid attention to, the battery will be charged and reversed, the positive and negative electrodes will become granular PBSO4, resulting in insufficient charge capacity of the battery, and even the battery will not work properly. Therefore, when charging must pay attention to the polarity, can not polarity charge and reverse charge.On the use of batteries and maintenance need to pay attention to some issues: , long-term storage battery does not use, it will slowly self-discharge, until scrap. Therefore, you should start your car regularly to recharge your batteries. Another method is to pull the two electrodes on the battery, note from the electrodes below the positive and negative two electrode wire, first pull the negative wire, or the negative wire and chassis disconnected. Then unplug the positive sign (+) at the other end, the battery has a certain life, to a certain time to replace. The order of electrode replacement is the same, but when the wires are connected in reverse, the positive electrode is connected first, and then the negative electrode is connected. When the ammeter pointer shows that the storage capacity is insufficient, it should be charged in time. The storage capacity of the battery can be reflected in the dashboard. As a temporary measure, you can switch to another vehicle. You can use the battery in their car to start the car. The negative poles of both batteries are connected to the negative poles, and the positive poles to the positive poles. Electrolyte density should be adjusted according to different regions and seasons. In the electrolyte loss, should add distilled water or special water. Avoid drinking pure water. Because pure water contains a variety of micronutrients, will have a negative impact on battery life.
