frozen electrolyte and check for leakage;
1.5.23.16
Cause of electricity insufficiency of battery
1.
The machine is parked for long, the leakage current is too high or additional electrical equipment
is applied, causing battery discharging;
2.
Abnormal operation such as switching on the electrical equipment for too long while the machine
is not started;
3.
The machine is started frequently;
4.
The fault of the machine charging system, for example, failure of the generator and its electronic
elements, the too low set charging voltage of the generator voltage regulator, the loose engine drive
belt, results in abnormal charging of the battery, thus causing electricity insufficiency, blacking of the
battery charge indicator or even the failure to start the machine.
5.
The unloaded battery is stored for more than 6 months;
Tips: The battery with insufficient electricity due to above causes can be recovered to normal working
conditions through correct charging processes.
1.5.23.17
Before charging the battery, check the appearance quality of the battery. Perform the
following operation if abnormality is found:
1.
If the battery shell is broken or the battery leaks acid, it shall not be charged. Replace the battery
after identifying causes;
2.
If the terminal post is broken, the battery shall not be charged; replace the battery after identifying
causes;
3.
The battery with white charge indicator shall not be charged. Replace the battery;
4.
If there is oxide scale on the surface, clean the terminal post and remove the oxide scale before
charging.
1.5.23.18
Charging of battery:
If incorrect operation is performed to the battery in charging status, it may explode; please follow the
processing regulations and instructions to charge the battery, and pay attention to the following notes:
1.
The mixture of oxygen and hydrogen may be released from the vent hole during the charging and
testing of battery; when the concentration of the hydrogen in the ambient air exceeds 4%, aopen flame,
a sparkle or high heat may cause explosion, so when charging, always keep ventilation and do not
smoke to prevent sparkles and open flame;
2.
The battery shall be charged under normal temperature; put on protective glasses when charging;
3.
Connect the battery’s cathode first after charging; disconnect its anode first when disconnecting
before charging;
4.
Connect the anode (+) charging clip of the charger to the positive (+) terminal of the battery, and
then the cathode (-) charging clip to the negative (-) terminal; secure the two terminals, and never
connect the batteries in series (24 V) for charging;
