Lead acid (Tubular) battery maintenance

A lead-acid battery is a type of battery in which the electrodes are mainly made of lead and its oxides, and the electrolyte consists of sulfuric acid and distilled water. It is mainly used for a variety of purposes such as stationary power systems, marine propulsion systems and de-vehicles, and is one of the most popular types of batteries, mainly because of its long history of development, mature technology, and favorable price, among other things.

However, when we use lead-acid batteries, we also need to be aware of the chemical reactions that occur in the batteries leading to degradation of the plates, which can lead to a decrease in the capacity and performance of the batteries. Therefore, we also need to maintain the lead-acid batteries in order to allow the batteries to perform their optimal function and to prolong the service lifespan of the batteries.

Maintaining lead-acid batteries
1. Battery Filler
In order to maintain the water level in the battery cells, you can use a specialized battery filler with a nozzle that allows you to add water to the battery cells precisely without spilling liquid, preventing safety accidents or damage to components.

2.Cleaning Brush
When cleaning the battery terminals, you can use a special terminal cleaning brush. The cleaning brush effectively removes corrosion and debris from the battery terminal posts, cable clamps and connections. Keeping the battery free from corrosion and debris buildup allows for effective power supply.

3. Battery lifting tools
Some lead-acid batteries are very heavy, the use of battery lifting tools can firmly grasp the battery to prevent electrolyte leakage, to avoid causing personal health and safety.

4. Avoid over-discharge
When the lead-acid battery is discharged to the cut-off voltage, the concentration of electrolyte will be very thin, over-discharge internal resistance will have heating phenomenon, and volume expansion. If the discharge current is too large, there will be obvious heating and deformation, then the concentration of lead sulfate will be very high, it is easy to form irreversible sulfation, and the internal resistance of the battery will increase, at this time the charging recovery effect is very poor, and even can not be restored. So we should avoid over-discharge to keep the battery in the best condition.

5. Avoid overcharging
Avoid overcharging is in the full charge, to immediately unplug the charger, not in the full charge continuous charging of the battery, overcharging will cause the active substance of the pole plate off, will cause the battery deformation and loss of water phenomenon. Also note that the charging current should not be too large, the charging current limit of lead-acid batteries is usually 20% of the battery capacity, overcharging may lead to internal damage or melting of the battery, which may cause thermal runaway phenomenon.

6. Choose the right charger
There are many charging methods for lead-acid batteries, and the correct charging method can prolong the service life of the battery, we have to choose the charger with the right parameters and specifications, and not to change the charger arbitrarily.

7. Proper storage of lead-acid batteries
If you plan not to use lead-acid batteries for a long time, you need to store them correctly. Before storage, it is best to charge the battery, and after a period of time you need to regularly charge the battery. You also need to avoid being in a high or low temperature environment, in which the life and performance of the battery will be affected, and store the battery in a dry and ventilated place to avoid other factors affecting the battery.
