Analysis of Perkins diesel generator battery how to charge normally

The purpose of normal charging of the battery is to restore the capacity of the lead battery in time, so as not to damage the battery due to long-term discharge. Normal charging can be used by two-stage constant current charging method, constant current before constant voltage charging method (or current limiting constant voltage charging method) and fast charging method. When the two-stage constant current charging method is adopted, the first stage is charged with 10h rate current until the single cell battery voltage reaches 2.4V, which generally lasts for 5-6h. The second stage uses 20h rate current to charge until the end of charging, this stage generally lasts about 8-10h.

After activating the battery, it is charged under the following circumstances, which is called normal charging.

① When the battery has been discharged (should be carried out within 24h).

② Partial discharge or small current gap discharge, although the discharge capacity does not reach half of the rated capacity, but the discharge time after more than a week.

③ The battery does not discharge within a month.

The end of the charge is marked by the following aspects.

（1）The positive and negative plates bubble violently.

（2）Electrolyte density reaches the specified value: fixed type battery rises to 1.200-1.220kg/L, mobile type battery rises to 1.280-1.30kg/L, and does not rise.

（3）The single cell voltage of the battery reaches 2.7-2.8V and does not rise.

 (4) The positive plate of the coated plate becomes brownish-red, and the negative plate becomes dark gray.

In the charging process, pay attention to the following aspects.

(1) Check the liquid level before normal charging. If the liquid level is found to be lower than the lower limit of the specified height, add pure water to the specified height.

(2) Should be the same model, discharge degree and new degree of the same battery in series charging.

（3）In the process of charging, the terminal voltage, current, electrolyte density and temperature of the battery should be regularly measured and marked, and the gas emergence of each battery should be observed.

(4) Before the end of each stage and the end of charging, the whole battery group should be tested in order to timely find the problem battery and avoid battery overcharging.
