Common diesel engines start the battery, there are two main types, one-free battery (dry), no need to add distilled water and adjust the concentration of the electrolyte, is full, no daily maintenance; the other is lead to add electrolyte Acid battery (wet), the first time you must use the battery, the charger can be used, and the daily need to be inspected and maintained. The battery replenishment is actually a more dilute sulfuric acid solution or distilled water than the primary concentration. The user is generally difficult to determine, and the specific gravity of the residual electrolyte in the battery is measured.

In the case of electricity, the specific weight of the electrolyte is higher than its factory standard, and the distilled water or supplement is added. If the proportion is low, it is necessary to add the original liquid. In general, the wet lead-acid battery loss is much moisture, and the sulfuric acid concentration is always easy to be high, so most is the addition of supplementation, as long as the distillation water is added.

Special reminder: When the concentration of sulfuric acid is high, the battery failure will be faster. The quality of the initial charging directly affects the capacity and life of the new battery, so it must be charged according to the requirements below: 1 Shortage, and cleaning work. 2, fill the battery fluid: open the battery cover, put the electrolytic solution of the appropriate density, slowly inject the battery, pay attention to the anti-orthogonal or liquid, generally fill the battery fluid to cover the electrolyte about 5 ~ 10mm.

3, charging: Correctly connect the charging equipment and battery, the positive electrode of the battery, the negative electrode of the battery, and charging the battery according to the regulations. Charging of the first stage: 1/1/1/1 / 16 of the charging current is approximately the rated capacity, the char bubble is released in the charging electrolyte, the single battery voltage reaches 2.4V.

Then reduce the current, transfer to the second stage charging, charging to the electrolyte dramatic sputum, density and voltage last for 2 to 3 hours, stability. All charging time is about 24-48 hours. The electrolytic temperature should be measured frequently during charging.

When the temperature exceeds 35 degrees, the charging current should be reduced, but the charging time is extended. If the temperature continues to rise to 40 degrees, the charging should be stopped immediately. During the initial charging process, in addition to special circumstances (the charging device is faulty, etc.

) is not allowed to be charged within 20 hours. 4 Liquid level height. When the density is higher than the specified value, a part of the electrolyte should be taken out, add an appropriate amount of distilled water; in turn, the partial electrolyte is removed, the electrolytic solution having a density of 1.

40 (strictly forbidden to directly inject the battery adjustment density of concentrated sulfuric acid), and make The liquid level reaches the specified value, recharge 30 minutes. If you still don't meet the requirements, it is repeated several times until it is adjusted until. After the new battery is first charged, the rated capacity is not reached, and it should be charged and discharge cycle.

Discharged with 20 hour discharge (ie, the current discharge of the rated capacity 1/20 is discharged to 1.75 volts), and then the normal charging current is sufficient. After one charge, discharge cycle, if the capacity is still less than 90% of the rated capacity, it should be charged, discharge cycle.

The battery is generally 3% of the charge and discharge cycle, and its capacity can reach 100%.
