Battery transport

The matters should be noticed in the transport of the battery:

Transport vehicles must be in compliance with the vehicle battery transport standard;

Inside the environment must be kept dry, clean, no debris, no water, no inflammable and explosive materials, no organic solvent; and take rainproof, moisture-proof measures;

The vehicle shall have good shock absorption function;

Stacking neat battery upright way, its height shall not exceed the prescribed number of layers on the packing box;

In the handling, transportation process, shall not be subject to intense mechanical impact and exposure to the sun and rain products, not inverted;

In the loading and unloading process, the product should be light moving light, to prevent a throw, tumbling, weight.

Battery use matters needing attention

1, to prevent over discharge

2, to prevent over charging

3, to prevent a short circuit

4, prevent loose connections and not in prison

Customer service detection step:

Goods inventory number, inventory number must be two or more people.

Unpacking, carefully observe the battery has no leakage, deformation, rupture obvious appearance problems, check whether the assembly and disassembly, shell bottom or side if there are metal foreign body nail, code changes human phenomenon.

Registration battery code, according to the customer, fill in consultation with a single model, the same type of registration and classification.

Classification detection, need discharge detection battery label, customer name, fill in the code group number, battery factory at the beginning of month, for pressure difference is greater than the 0.2 volt battery do voltage flattened processing, the whole group full of after discharge, the initial pressure measurement is less than 0.2 volt battery, direct discharge pressure in the above 12 V battery only put the voltage difference, achieve charging schedule requirements do capacity detection, timely registration discharge data, the standard "T" standard battery charging classification piled up to be processed.

Detection method:

1, add backward battery electric, first of all to backward battery charging rechargeable single, only using a single charger or whole group charger series resistance wire, only the maximum charge voltage of 15 volts each (12 volt battery charging current of 5 amps) within, flat after the entire group charge detection capacity.

2, determine the battery short circuit detection, if the initial test battery voltage too high and there is a less than 11.60 volts, constant current charging whole battery fever existed discharge phenomenon, such as single heating is short, if the initial test voltage above 11.60 charging too fast or discharge in 1 minutes is the short circuit battery.

3, will be fully charged battery in accordance with the 2 hour rate discharge detection, into 25 C capacity is less than or equal to the rated capacity of 30, can determine the existence of short circuit of the battery group.

4, off lattice cell, careful measurements of the open circuit voltage of each battery, about 11.80 volts in general, short-circuit sparking discharge on the low voltage battery, if the ignition spark free can determine the battery off lattice; charging charger series resistance wire, using a multimeter to measure voltage, voltage directly soared is determination of off lattice.

5, the liquid leakage detection and determination of the battery, do visual inspection, find out the leakage position of acid leakage; pry the cover piece look have no signs of leakage, and then open the safety valve with no observation of internal flow of electrolyte in the charging process; acid leakage check wiring terminals of the cut, color rubber check "O" type ring is intact; check 10AH, bottom shell parts of head cell 12AH with welding is broken, the multimeter is used to measure the pits and welding head voltage forming circuit is judged to have holes.

Unable to determine the reason for the battery can call to find return reason to do anatomy analysis.

Common faults of lead-acid battery

1, the battery liquid leakage

Leakage phenomenon common:

One is between the upper cover and the bottom groove seal is not good or due to the collision caused by the cracks, sealing glue, two is a safety valve for acid leakage liquid leakage; the three terminal at the acid leakage leakage; four other parts appear acid leakage leakage.

Examination and processing method:

First appearance inspection, find out the acid leakage liquid leakage location. Pull the cover check the safety valve has no leakage around the acid leakage traces, then open the internal safety valve checking the battery has no flowing electrolyte. After completion of the work, if not found abnormal, do because of tightness inspection (into the water inflating, observation of cells with and without bubbles and bubbles emerge, it shows that the acid leakage leakage). Finally, in the charging process, observe whether to produce a flow of electrolyte, that is if there is reason for production. In the process of charging, with flowing electrolyte should be exhausted.

2 deformation

The fault phenomenon

Battery deformation not burst, there is often a process. The battery in the charging capacity to about entering the 80% high voltage charging area. Then, in the positive first precipitated oxygen, oxygen through the hole in the partition, to negative electrode. The resurrection of oxygen reaction in the negative plate:

A heat generating reaction, when the charge capacity reached 90%, oxygen generating speed increases, the negative began to produce hydrogen. To increase the amount of gas is the battery internal pressure exceeds the valve opening pressure, the safety valve open, gas to escape, the ultimate performance for the loss.

2H2O=H2+O2??

With the increase of the battery cycle times, water gradually reduced, the result of the battery there is the following:

(1) oxygen "channel" to become clear, positive generated oxygen easily reach the cathode through the "channel".

(2) decrease in heat capacity, heat capacity of the battery is the biggest water. The water loss, the battery capacity is greatly reduced, the heat produced the battery temperature rise quickly.

(3) due to the ultra-fine glass fiber separator after dehydration shrinkage occurs in the phenomenon of the battery, so that the positive and negative plate adhesion variation, larger resistance, charge and discharge process of heat increase. Through the above process, generated inside the battery
