双登蓄电池需要进行定期维护，干净干燥如果极板上有灰尘，会导致极板间短路，电池会自行放电。极板上的表面污垢和氧化物应清除，脏水也应防止流入电池，液体帽通气孔堵塞时，充气产生的气体无法逸出。

　　双登电池在严重的情况下，通风孔需要保持畅通，电解质高度当电池使用时，由于电解质水蒸发和溶液溢出，电解质表面会下降。此时，极板容易暴露在空气中，导致极板的电容降低和硫化。电解质表面的高度应定期检查。电解液不纯，如果用工业硫酸代替化学硫酸。使用自来水或河水代替蒸馏水添加到电池中会导致自放电并降低电池的使用寿命，电解质的比重当电池充放电时，电解液会变得更厚或更薄。当检查电解质的比重时，我们可以知道电池储存电的程度。

Shuangdeng battery needs regular maintenance, clean and dry if there is dust on the plate, will lead to a short circuit between the plates, the battery will discharge itself.Dirt and oxides on the surface of the plate should be removed. Dirty water should also be prevented from flowing into the battery. When the vent hole of the liquid cap is blocked, the gas generated by charging cannot escape.

Shuangdeng battery in serious cases, the ventilation hole needs to be kept unimpeded, electrolyte height when the battery is used, due to electrolyte water evaporation and solution overflow, electrolyte surface will fall.At this point, the plate is easily exposed to air, resulting in the plate capacitance reduction and vulcanization.The height of the electrolyte surface should be checked regularly.The electrolyte is not pure, if industrial sulfuric acid is used instead of chemical sulfuric acid.Using tap water or river water instead of distilled water to add to the battery can lead to self-discharge and reduce the battery's service life, electrolyte specific gravity when the battery charge and discharge, the electrolyte will become thicker or thinner.When we check the specific gravity of the electrolyte, we can know the extent to which the battery stores electricity.
