Most of the cars sold now are equipped with maintenance-free battery, so to check the battery liquid just check the window on the battery, look at the color of the window can know the condition of the battery liquid, is not necessary to replenish the car battery.

Usually the window will appear green or blue, which means good

White means low power. If it's black, you'll need to get a replacement at the service station.

Traditional battery Look at the battery electrolyte

If it is a traditional battery, then battery liquid to maintain between the upper and lower limits of the label, if too low to quickly add distilled water, and can only use distilled water, otherwise it will shorten the life of the battery.

Battery The electrolyte level of each cell battery should be 10 to 15mm higher than the plate.

(1) Use a glass tube with an inner diameter of 3-5mm, one end of which is vertically inserted into the battery filling hole.

And against the plate guard, the other end with your finger,

② The use of its vacuum, when the glass tube lifted, the electrolyte suction into the tube,

Electrolyte height is the value of electrolyte above the plate.

When the electrolyte is insufficient, distilled water should be added. Sulfuric acid solution is not allowed to be replenished unless it is ascertained that the level reduction is due to electrolyte spillage. Because the normal reduction of electrolyte level is caused by the evaporation of electrolyte water and electrolysis.

After a period of time, the capacity of the battery will slowly reduce, and the distance will be shorter and shorter. In fact, this situation is not a problem with the quality of the battery, but the battery water loss! Because once the battery has been charged, large current discharge and other problems, it is easy to generate heat and form water steam, a very small part of the water steam will be lost, over time the battery will appear "water loss" state. So what can you do if your car battery loses water? Here are the steps to properly rehydrate your car battery.

Step 1: Pry open the top cover of the battery. Each battery connection is different, in pry open must be based on the connection of the battery, do not hit too hard, damage the cover.

Step 2: Open the rubber cap to expose the vent hole. Electric car batteries have six rubber caps that exhaust gas. When opened, they reveal vents through which you can see inside the battery. Part of the battery exhaust hole bottom valve can be rotated open, this time can be opened through this.

Step 3: Open the end cover for water supply. Normally, the surface of the battery is wet, but if the battery loses a lot of water, it will dry up. After opening the end cover, use the dropper to inject water into the battery. After adding good water, cover the occluder in the exhaust hole. Pay attention not to cover the exhaust hole dead.

Lham has always focused on battery accessories, supporting related business, in the field of safety, convenience, maintenance of automotive battery, industrial battery has a deep accumulation of technology and practical technology patents. At present, the main products of the company are: battery status indicator, battery safety valve (exhaust bolt), battery equalizer, waterproof permeator valve, battery automatic water refill device, battery water shortage alarm, battery water gun and other products.
