THE LEAD-ACID BATTERY
In the automobile industry, Lead-Acid Battery is one of the well-renowned name and the oldest type of rechargeable battery. It comes with low costs led and a relatively large power-to-weight ratio It is considered powerful by providing a high voltage to automobile starter motors and vehicles.
It is comparatively inexpensive to new and high-performance technologies. Mostly lead-acid batteries are used in a large range of industrial sectors, as backup power for mobile phone towers, maintaining and providing high power speed in hospitals, as well as considered as a trustworthy stand-alone power system.
LEAD ACID BATTERY MAINTENANCE
Are you aware of the reason behind the lead-acid batteries breakdown and lose capacity? No? The reason is battery sulfation, it is considered that 80% of issues are caused by this. But don’t worry if you’re using the right tools and give a little time for the maintenance so you’ll make your batteries perfect and keep its performance reliable. Semi-traction batteries, Starter batteries, Stationary batteries, and even traction batteries all of them are need proper maintenance to give you good performance.
Every year Lead-acid battery industry claims their sales figure of approximately 15 billion USD worldwide. Proper maintenance of a lead-acid battery is quite difficult unless you are an expert in the electronics field.
Here are some tricks and tips for you which will help in the maintenance of your lead-acid batteries as well as to guide you that what is the proper way to charge the battery.
Before going to charge your lead-acid battery with an external charger, it is always recommended to be ?” stated the charger manufacturer.
- Place the battery away from the open flames and sparks
- Unplug the charger before removing, rocking, or attaching the terminal clamps
- After removing the vent caps, keep them in a save place
- Always charge the battery in an open or well-ventilated area
You should have to follow the instructions stated by the battery charger manufacturers to avoid harm or overheating.
Explosive gases are produced while the highly dangerous charging process can be burned by a different source which includes naked flames, sparks, and static electricity. It is highly recommended to wear Personal Protection Equipment i-e chemical resistant gloves, safety glasses, and overalls.
INSPECTION OF THE BATTERY
Before taking a start, first, you have to know a little bit about your lead acid battery. Make it sure that you know its compartment size, exact system voltage as well as the energy requirements like for which purpose, you’re going to use this battery, once you have an idea about all these things then you may start work over it.
More than this, you must also confirm the type of lead-acid battery used, selecting from gel or AGM ones to deep-cycle flooded batteries. By selecting the right type will beneficial for your further energy requirements.
However, if you are not sure that which type of battery is better to use and it is recommended to contact your authorized equipment manufacturer for further technical support.
Besides then their type, all batteries are required to be stored at proper temperatures and in an appropriate condition. Normally batteries require approximately 59 degrees Fahrenheit or 15 degrees Celsius temperature.
Normally lead-acid batteries are recommended a full charge before placing it in storage. Nonetheless, an intense temperature of up to -40 degrees Celsius can settle for most chemistry.
A sealed lead-acid battery can be stored easily for up to two years. Before using any type of battery whether it’s new or old, it is suggested to check it first the voltage and the specific gravity and then further charge the battery at least up to 70%.
Always remember that you should manage to place your batteries away from extreme heating or freezing points. In the discharge state, lead-acid batteries can be freeze easily so this is essential to bear in mind. Always keep batteries in a dry and cool place and make sure that you have charged them properly before planning to store it for a long period.
The charging method used by the lead-acid batteries is the constant voltage and the constant current. It means that when the upper charging voltage limit is attained (the point at which you lead-acid battery is completely saturated), the regulated current is ready to pass to your device.
Normally 12 to 16 hours are required by the batteries for the 100% charge but this may exceed up to 48 hours for the large or full-sized stationary batteries.
Further, you can decrease the full charging cycle up to 8 hours by using the higher charging currents or the different-stage charge methods.
This has to be remembered that there are three different phases of charging to charge all lead-acid batteries i-e from the (CC) constant current stage -to- the float charge state.
It is noted that a lead-acid battery is normally charged up to 70% in less than 8 hours on the constant current charge and the other 30% charge can take at least 10 hours with a slower topping charge to make it complete to 100%.
Topping charge is considered the most important as it checks the ability of the battery to arrive at the point of a full 100% charge.
The battery will start losing its power to recognize a 100% full charge if your battery is gradually deprived of the top charging, in this way battery will automatically lose its energy faster and easier.
It is recommended by the experts that always charge your lead-acid battery in the open or ventilated areas to prevent it from overheating and try not to allow the battery to arrive at its freezing point. At the temperature of 49 degrees Celsius, avoid charging your battery.
PROLONGING THE LIFE OF LEAD-ACID BATTERIES
Avoid electrical short, acid stratification or sulfation, dry out and corrosion, if you want the prolonging the life of your lead-acid batteries. Remember, lead-acid batteries require at-least 50 full charging cycles to achieve its peak posting where it gives the best performance.
