Instruction for Daily Maintenance

The battery is FIRSTEK lead acid type Automotive / automobile / car / truck battery. It is guaranteed under FIRSTEK company policy (www.firstekbattery.com)

Check battery, terminal parts, battery holder, specific gravity of electrolyte level periodically if there are problems, and adjust them, if required.

￭Adding Water

Keep the electrolyte level to the proper height by adding distilled water only.

The electrolyte level should be maintained properly. (Do not expose active plates to air and do not over fill)

Never use diluted sulphuric acid in lieu of distilled water.

In the cold season, electrolyte should be agitated fully by gassing during charge after adding distilled water.

￭Charging

If the engine does not start, the head light becomes dim or horn sound weak, or specific gravity of electrolyte is below value, battery is insufficiently charged, so place on charge until each cell gasses freely, the voltage stops rising, and the specific gravity reaches to the value, and continues a constant value for more than one hours.

￭Keeping battery clean and dry

Keep the outside of battery clean and dry. If terminal parts get rusty, ignition becomes hard, charge becomes impossible.

If the terminal cable rust is observed, remove the rust with water or hot water and dry up. Apply with a good quality protective spray after polishing.

Instruction for putting FIRSTEK dry charged auto/car battery into service

· Fill the battery with an electrolyte (refined sulfuric acid) of appropriate gravity. When the electrolyte is filled, the temperature shall not be lower than 15 ℃ (60 ° f) or higher than 30 ℃ (86 ° f). Note: if the battery vent plug is sealed with tape, discard the tape.

· After charging, let the battery stand for a period of time to recharge. If the electrolyte level drops, add more electrolyte until the appropriate level is reached.

· Charge at an appropriate rate until the battery gas is released freely. The voltage and specific gravity are constant. Measure three times every 30 minutes.

· Do not allow the electrolyte temperature to rise above this value during charging. If this temperature is reached, reduce the charging current.

· If the electrolyte is reduced during charging, make up the electrolyte to a proper height with distilled water.

· When the battery is fully charged, the specific gravity of electrolyte is given. If the specific gravity is higher than the maximum, part of the electrolyte shall be taken out and replaced with distilled water. If it is lower than the minimum, use a small amount of 1.400 specific gravity sulfuric acid instead. After adjustment, put the battery in the state of charge, and mix the electrolyte for more than 1 hour.

· After charging, adjust the electrolyte to a proper height.

· Tighten the vent plug. Clean any electrolyte splashed on the battery. ·The battery is ready to use.

Tips for Car Batteries

New Battery Charging

The first charge of a battery is called initial charge, which has a great influence on its service life and charge capacity. If the charge is insufficient, the charge capacity of the battery is not high, and the service life of the battery is short; if the charge is excessive, the electrical performance of the battery is good, but the service life of the battery will also be shortened, so the new battery should be charged carefully. For ordinary batteries, the initial charging must be carried out according to the charging specification before use. For the dry charged lead-acid battery, according to the operation manual, if it needs to be used within the specified two-year storage period, it can be put into use without charging as long as the electrolyte of the specified density is added and kept for 15min. However, if the storage period is more than two years, due to partial oxidation on the plate, in order to improve its charge capacity, supplementary charging shall be carried out before use, and it shall be reused after charging for 5h-8h.

Recharge

Some drivers often neglect to recharge the battery in use. As the battery is not fully charged on 

the vehicle, it is easy to cause the electrode plate to be vulcanized; at the same time, the charge and discharge in use are unbalanced. If the discharge is greater than the charge, the battery will be in a state of power loss for a long time, and the electrode plate of the battery will be vulcanized slowly. This kind of chronic vulcanization will reduce the charge capacity of the battery until it is unable to start and greatly shorten the service life of the battery. In order to reduce the active substances on the battery plate in time, reduce the plate vulcanization, improve the charge capacity of the battery and extend its service life, the battery in use should be recharged regularly.

Overcharge

The battery is often overcharged, even if the charging current is not large, but the electrolyte "boils" for a long time, in addition to the small particles on the surface of the active material easy to fall off, it will also make the grid frame over oxidized, resulting in the loose separation of the active material and the grid frame.

Polarity Reversal

Due to the different materials of the positive and negative plates of the battery, in addition to the active substances, the negative plates are also added with barium sulfate, humic acid, carbon black, rosin and other materials to prevent the negative plates from contracting and oxidation. In addition, the number of negative plates of each single cell battery is always more than the number of positive plates, and the negative plate is slightly thinner than the positive plate. When the initial or supplementary charging of the battery is carried out, if the polarity is not paid attention to, the battery will be charged reversely, and the positive and negative electrodes will almost become coarse-grained PbSO4, resulting in insufficient charge capacity of the battery, unable to work normally, and even lead to battery scrap. Therefore, pay attention to the polarity when charging, and do not reverse the polarity.

Density "better small than large"

Some drivers think that the higher the electrolyte density is, the lower the discharge degree of the battery is, the higher the terminal voltage of the battery is, the greater the charge capacity is, and it can prevent the battery from freezing due to the freezing of the electrolyte in winter. Therefore, when adjusting the electrolyte density, not only the original electrolyte density is higher than the specified value, but also some distilled water is used to be added in normal use Different density of electrolyte results in higher and higher density of electrolyte. In fact, this approach is very wrong.

As an important sign to measure the discharge degree of battery, the electrolyte density is based on the premise that the original electrolyte density has been determined. Adding electrolyte of different density only means to increase the density of the original electrolyte, even if the measured electrolyte density is high, it cannot mean that the discharge degree is low; increasing the electrolyte density can improve the battery terminal voltage and charge capacity is relative On the one hand, increasing the density of electrolyte can improve the electromotive force of the battery and increase its terminal voltage and charge capacity, but on the other hand, if the density of electrolyte is too high, the viscosity and internal resistance of the electrolyte will increase and the permeability will decrease, on the contrary, the voltage and charge capacity of the battery will decrease. Moreover, if the density of electrolyte is too high, it will also cause more plate vulcanization and diaphragm corrosion The service life of the battery is reduced.

Ignore the check of electrolyte level

Check the electrolyte level of the battery regularly. If the amount of electrolyte is not enough, the upper part of the electrode plate will contact with air and be vulcanized, which will reduce the charge capacity of the battery and shorten its service life. Generally, the inspection shall be conducted once a half month in winter, and once a week if the high temperature water is easy to evaporate in summer. The liquid level of electrolyte is generally 10 mm-15 mm higher than the protection net of electrode plate. Mark the lower limit, so the electrolyte level can only be within the specified range. Although distilled water does not need to be added in use, it is also necessary to check the electrolyte level in combination with the regular maintenance of the car. If it does not meet the requirements, it should be adjusted.

Electrolyte level "better high than low"

When some drivers add electrolyte or distilled water to the battery, they often take the wrong way of "better high than low" to the liquid level. The electrolyte level is too high. In the process of vehicle driving, the electrolyte is easy to overflow from the vent hole and corrode the pole, resulting in poor contact or early damage of the pole. The electrolyte accumulated on the battery cover will make the positive and negative poles connected to form a circuit, which will cause the battery to discharge itself. At the same time, the high electrolyte level will cause the internal pressure of the battery to be too high, and even cause the battery to explode when it is serious.

Add at will

In the daily maintenance of battery, when the electrolyte is insufficient, distilled water should be added generally. But sometimes the electrolyte reduction is caused by the crack of the battery shell or the electrolyte leakage caused by the loose cover of the charging hole. While some drivers often don't pay attention to the difference between electrolyte leakage caused by battery shell damage or other reasons or normal loss when checking the liquid level. As long as the liquid level of electrolyte drops, distilled water will be added, resulting in obvious electrolyte density.
