What are the misunderstandings of maintenance-free batteries?

Maintenance-free batteries need to be maintained Everyone has the following misunderstandings about maintenance-free batteries. Misunderstanding 1: When using maintenance-free batteries, simply think that maintenance-free means that there is no need for any maintenance. Misunderstanding 2 There is no need to deal with the corrosive matter on the surface of the battery pole post terminal, as long as it is not loosened. Corrosion appears on the exterior, and the inner surface of the terminal will also corrode, which will increase the resistance value and affect the normal charging and discharging of the battery. It must be dealt with in time. Misunderstanding 3: When the liquid level is low, replenish electrolyte or add pure drinking water instead of distilled water. If the electrolyte containing sulfuric acid is added, the electrolyte concentration inside the battery will increase, boiling, acid fog, etc. may occur, which will seriously affect the service life of the battery; use pure drinking water instead of distilled water, which contains a variety of trace elements. It has an adverse effect on the battery. In fact, maintenance-free storage batteries just don't always check the electrolyte level, but it definitely does not mean that maintenance-free storage batteries don't need to be managed after being installed in the car. In fact, the maintenance-free battery needs some maintenance during use. If the maintenance is proper, its service life can be greatly extended.
