A. Check and correct electrolytes
The electrolyte density is based on 25 ℃.Therefore, when m easuring, if the tem perature of the electrolyte
is higher or lower than 25℃, every 1℃ higher, should be measured from the actual density value plus
0.0007;On the contrary, lower than 25 ℃, every 1℃ , should be minus 0.0007;If the temperature difference
is large,
Can be corrected by pressing the following formula:
Standard temperature of electrolyte (25℃) Density is converted acco rding to the following formula:
D25 = Dt + 0.0007(T-25)
D25 -- electrolyte density at 25℃
Dt -- T ℃ m easured electrolyte density
T -- Temperature of electrolyte when measuring density
Under the condition of normal working of charging function, the density of 1.26±0.005(25 ℃) tem perature
below 30℃ sulfuric acid electrolyte into the battery, liquid level requirem ents higher th an the protection
plate 0.6 ~ 1 in.
Leave the battery to rest for 3-4 hours, no more than 8 hours. Initial charging can be carried out only
when the liquid temperature drops below 35℃.If the electrolyte level drops after standing, the electrolyte
should be replenished.
The discarded batteries must be recovered and stored in the specified environmental protection area or
the specified waste disposal area in accordance with the local laws and regulations, and the work must
be carried out by qualified professional companies.
