The storage battery is a kind of chemical energy directly into electrical energy device, is designed according to the rechargeable batteries, rechargeable by reversible chemical reactions, usually is refers to the lead-acid battery, it is one of the battery, belongs to the secondary battery.

Battery is a kind of chemical energy directly into electrical energy device, is designed according to the rechargeable batteries, rechargeable by reversible chemical reactions, usually is refers to the lead-acid battery, it is one of the battery, belongs to the secondary battery. How it works: when charging use external power to make the internal active substances, to store the electric energy to chemical energy, need discharge to convert chemical energy to electrical energy output, such as mobile phone battery is commonly used in life.

Fill it with sponge lead lead substrate grid (body) is also called the grid as negative, fill lead dioxide lead substrate grid as the anode, and the density of 1.26-1.33 g/MLG/ml dilute sulphuric acid as electrolyte.Battery during discharge, the metal lead is negative, the oxidation reaction, generate the lead sulfate;Lead dioxide is positive, reduction reaction, generate lead sulfate.When used in dc rechargeable batteries, the poles producing elemental lead and lead dioxide respectively.Remove the power supply, it back to the front of the discharge state, form a chemical battery.Lead-acid batteries are repeatedly charging and discharging, its monomer voltage is 2 v, the battery is made up of one or more of the monomer battery pack, referred to as "battery, one of the most common is 6 v, 12 v battery, there are other 2 v, 4 v, 8 v, 24 v battery.With such as the car battery (commonly known as battery) is 6 lead battery series into the 12 v battery pack.

For traditional dry lotus lead battery (such as car dry battery, dry lotus motorcycle battery, etc.) in use after period of time to add distilled water, keep the dilute sulphuric acid electrolyte density of 1.28 g/ml;Its use until the termination of life are no longer need to add distilled water.

Chemical reaction equations are as follows:

Overall reaction: the pb (s) + pbo2 (s) + 2 volunteers - h2so4 (aq) reversible symbol 2 pbso4 (s) + 2 h2o (l)

Discharge: negative pb (s) - 2 - + so42 - (aq) = e pbso4 (s)

Pbo2 (s) + 2 e - + so42 - (aq) + 4 h + (aq) = pbso4 (s) + 2 h2o (l)

The total pb (s) + pbo2 (s) + 2 - h2so4 (aq) = 2 pbso4 (s) + 2 h2o (l)

Electrolytic cell when charging

Cathode pbso4 (s) + 2 e - = pb (s) + so42 - (aq)

Anode pbso4 (s) + 2 h2o (l) - 2 e - = pbo2 (s) + so42 - (aq) + 4 h + (a

1, out of the box, and check

Handling:

Prohibited in the terminal area stress, prevent terminal sealing damage and crack;

Avoid battery inversion, a throw or hit;

Absolutely avoid using steel wire and other metal wire, prevent the battery short circuit.

The appearance of the check boxes, battery - no damage;

Check: the battery number, accessories - qi, full;

Refer to: manual, installation drawing, matters needing attention.

2, before the installation

After check the battery without exception, install it in the designated location (battery room);

If the battery in the battery room, should as far as possible put it in the battery room lowest place;

Avoid install the battery in near heat sources (such as transformer);

Because the battery storage of flammable gas may be produced, when installation should avoid close to produce spark device (such as fuse);

Before connecting, polished battery terminals, make its present metal light;

Careful conductive material sub battery positive and negative terminals.

Multiple batteries are used together, the first to ensure correct connection between the battery, connect the battery and charger or load again.In this case, the battery positive electrode should be connected to the charger or load of the anode, cathode and anode connection.If the battery connected to the charger is not correct, the charger is damaged, it is important to note that don't connection error.Bear in mind that connected correctly.

Note when wiring connection is firm, but not too hard, in order to avoid damage to the terminal, recommended tightening torque are shown in table 1.Do not use too much force in the terminal department, each connection nuts and bolts must be tightened, tightening torque according to the table.

A lot of people think the battery is a very simple thing, also did not much care for maintenance at ordinary times, in fact, in the car for daily use, the battery is is one of the most important part, shall not be careless.

Battery should be paid attention to daily use?Reporter specially interviewed Zhou Yongjian evergreen storage battery co., LTD., vice general manager and in the male Xu Jingxiong industry &trade co., LTD. General manager.Zhou Yongjian said, batteries have starting batteries and batteries, and start the battery including maintenance free batteries and "water" cells.In terms of the car, the commonly used are starting batteries, because it can make the vehicle energy storage, and then released, so start with a good quality battery, the start-up is also more quickly.

Brand battery more secure.

The battery in the use and maintenance need to pay attention to some problems:

1. The battery for a long time need not, it will slowly discharge by oneself, to scrap.At regular intervals, therefore, should start a car, for battery charging.Another way is pulled down the two electrodes on the battery, unplug from the electrode column that should pay attention to both positive and negative electrode thread, to remove the negative line first, or remove negative and chassis connections.Then pull with the positive sign (+), on the other side of the battery service life to a certain extent, to a certain period has to be replaced.When replacement should follow the same order, but in the up electrode wire, order, by contrast, take the positive first, and then connect the cathode.

2. When the ammeter pointer display storage capacity is insufficient, the charge in time.Battery storage capacity can be reflected in the dashboard.Sometimes found that power is not enough in the way, the engine stalled again won't start, as a temporary measure, can seek help from other vehicles, vehicle battery with them to launch vehicle, connected the two battery anode and the cathode, the anode and the anode is connected.

3. The density of the electrolyte should according to different regions, different season, according to the standards for the corresponding adjustment.

4. When loss of electrolyte adding distilled water or dedicated rehydration.Drink pure water instead of avoid by all means.Because water is contained in a variety of trace elements, the battery can cause bad influence.

5. When starting car, uninterrupted use the chance to lead to battery damage due to excessive discharge.Every time the use of the correct way is to launch a car in the total length of not more than 5 seconds, restart time interval is not less than 15 seconds.In the case of start many times still no car from circuit, ignition coil, or oil, and other aspects to find reasons.

6. Daily route should be regularly check whether the battery cover holes.If the battery cover holes blocked, produce hydrogen and oxygen to row out of the electrolyte expands, the battery shell burst, affect battery life.

7. Check the battery level of positive and negative sign of oxidized.Can often watering the wire connection of the battery with hot water, with a clean copper wire brush to clean up, and coated with butter.

8. Check each part of the circuit without aging or short circuit.To prevent the battery retire ahead of schedule because of the excessive discharge.

9. Ban kui electric storage battery, if out of idle days recharging, plate is easy to appear the sulfuric acid salinization, capacity declined.

10. Periodic inspection: periodic measurement of single battery voltage, if there is a battery voltage is lower than 10.5 v, this should find pit inspection or repair, in order to avoid damage to the other two pieces of good battery.

11. The design of the electric bicycle capacity is 75 kg, avoid overweight, please use pedal power during start and uphill.

12. Battery capacity decreases with the decreasing of the temperature in winter it is normal phenomenon, on the basis of 20 ℃, average - 10 ℃ when capacity is 80%.

13. Keep clean on the surface of the battery for a long time, for no exposure when vehicles, vehicles should be parked in a cool, ventilated, dry place.

14. When batteries need to be stored for a long period must be adequate electricity, general complement once every month.

15 vehicles when starting, uphill, overload, against with pedal power, so as to avoid large current discharge.

16. When charge to use the special charger, in a cool ventilated place, avoid high temperature and humidity.

17. Do not use organic solvent cleaning storage battery shell.

18. Do not use the battery positive and negative extremely short circuit, lest produce risk.

19. Forbid a discharge: when the dashboard under-voltage display lamp glow red, suggests that power into the hunger zone, should charge in a timely manner.

20. Forbid a charging: charging time should be according to the length of the range is different, the longer the mileage, charging time is long, short conversely.

21. If a battery fails, please send it to the manufacturer or the relevant authorities to properly handle the authorization.Please don't discarded so as not to cause environmental pollution.
