How to maintain the SINOTENG Excavator Battery?
(1) Maintain a High Electrolyte Level
According to operating requirements, the electrolyte level should be 10-15mm higher than pole plate. In order to check this, you can insert a 150mm long glass tube (inner diameter: 4～6mm) vertically into the filling opening until it is in contact with top edge of the pole plate, then press the upper opening of the glass tube with your index finger and take the tube out with your thumb and ring finger. The electrolyte height in the glass tube is the exact height you need. If this height is less than 10mm, you'd better add a certain amount of distilled water timely. Please don't add any liquid like spring water, river water and tap water, as well as dilute sulphuric acid.
(4) Regularly Inspect the Density of Electrolyte
Electrolyte density should be in accordance with the specific season and other conditions. For example, the density of electrolyte is relatively higher in winter.
