1)Principle “find out the hidden trouble and insure the safety “should be complied
when make test on the battery.
2)Daily maintenance and performance analysis should be carried out strictly
according to the processing plan.
3)Battery parameter setting and operation should be strictly complied with the
maintenance rules and related requirement.
4)Always wear insulated gloves when handling the batteries to avoid electric
shock. Make sure the metal instrument is insulated.
5)Use instrument and meters which meet the test requirement.
6)Physical articles:
(1) Check whether the post and connection is clear or not, whether there is any
appearance of oxidation or erosion. In case it is serious, please clear it and reduce the
resistance.
(2) Check there is any loosen connection, if any, please tighten them up.
(3) Check there is any appearance of acid climbing, leakage of liquid, and
whether there is liquid overflow around the safety valve.
(4) Check there is any damage, leakage and distortion on the battery case and
the post without any damage and distortion.
(5) Check there is any abnormally temperature increase on the battery and it’s
connection.
7)Check and adjust the set of related parameters.
(1) Check the float voltage, equalization voltage, float charging current is normal
or not on the base of technical parameters and site environment. If not, please
process it on time.
(2) Check whether the limited charge current set is correct or not, if not, please
adjusted it on time.
(3) Check the alarm voltage (below voltage and over voltage alarm) of the battery
set is correct or not. If not, please adjust it on time.
(4) If there is off- load set, please check the off - load voltage is correct or not, if
not, please adjust it on time.
