Labels: 1. The new battery must be initially charged and should be charged reasonably. The initial charge is the first charge of the battery, which has a great impact on the service life and charge capacity of the battery. If the charge is insufficient, the charge capacity of the battery is not high, the service life is short, and the number of charging times is increased; if the charge is over, the electrical performance of the battery is good, but it will also damage the battery itself and shorten its service life, so a new battery must Carry out the initial charge carefully. For ordinary batteries, the initial charge must be carried out according to the charging specifications before use. For dry-charged lead storage batteries, if they need to be used within the two-year storage period specified in the instruction manual, they can be put into use after adding the electrolyte of the specified density and standing for 15 minutes without charging. However, if the storage period exceeds two years, due to partial oxidation on the electrode plate, in order to increase its charge capacity, supplementary charging should be carried out before use, and then used after charging for 5-8 hours. 2. The battery cannot be overcharged. The above point has been explained. The initial charge of the battery should not be overcharged, but after normal use, it is often overcharged. Even if the charging current is not large, the electrolyte 'boils' for a long time, except for the fine particles on the surface of the active material. In addition to being easy to fall off, the grid frame will be excessively oxidized, causing the active material and the grid frame to loosely peel off. 3. The accumulator should be recharged regularly. As for the left accumulator, the battery has self-discharge. Therefore, the battery should be recharged regularly to prepare for the battery to discharge for too long and shorten the battery life. 4. When charging, pay attention to whether the two poles are opposite. Because the battery positive and negative plate materials are different, in addition to the active material, the negative plate is also added with barium sulfate, humic acid, carbon black and rosin to prevent the negative plate from shrinking and Oxidation. In addition, the number of negative plates of each single cell battery is always one more than the number of positive plates, and the negative plate is slightly thinner than the positive plate. When initial charging or supplementary charging of the battery, if you do not pay attention to the polarity, the battery will be reversed, and the positive and negative electrodes will almost become coarse-grained PbSO4, resulting in insufficient charge capacity of the battery, failure to work normally, or even causing the battery scrapped. Therefore, you must pay attention to the polarity when charging, and do not reverse the polarity.
