Lead-calcium Battery – Charging, Comparison and Recycling
A lead-calcium battery is a special type of lead-acid battery with a few variations. The lead-acid battery manufacturer tried to improve the existing battery and came up with a lead-calcium battery.
The calcium battery is maintenance-free; thus, they are fully sealed. Calcium substitutes antimony in the battery plates, and this makes calcium batteries unique and more efficient. A calcium battery is resistant to corrosion; it has no excessive gassing, less water usage, and reduced self-discharge.
With the improvement in the areas mentioned above, you are sure that this battery will serve you better. The amount of calcium used on the battery terminals is about one percent; thus, most of the components used in making the battery are lead.
Therefore, this is a battery of interest to many people because we do not have time to check our batteries frequently. The current generation is moving towards sealed and maintenance-free batteries. With calcium coming into play, your terminals won't corrode, and the cables won't wear out.
However, we need to look at the process of charging this lead-calcium battery, the difference between a lead-calcium battery, and the methods that can be used to recycle the battery. Thus, it is a good idea to follow this piece of writing to the end.
Lead-calcium Battery Charging
The method and the process of charging any battery is always crucial. Never purchase a battery without asking for directions on charging it because you might ruin your battery after a few days. Therefore, you need to be keen on your lead-calcium battery because you cannot afford to destroy it.
The ordinary lead-acid battery requires a charging voltage ranging from 2.15 Volts per cell to 2.35 Volts per cell. However, the charging voltage of a lead-calcium battery is 14.8 volts. This voltage ensures that the recombination process in the battery occurs appropriately.
The above-mentioned charging voltage of 14.8 volts indicates that it will be almost impossible to trickle-charge a lead-calcium battery. If you are using the battery on your car and the alternator can charge it, it will always ensure the alternator is actively working.
However, you need to be careful with this calcium battery because it has a low voltage but a high current. No one can think of making the terminals meet because it will produce a massive fire or explosion.
The good thing with lead-calcium batteries is a low self-discharge rate, meaning that it will work for an extended period. However, the lead-calcium positive plate can grow because of oxidation caused by battery overcharge. Therefore, you should be careful not to overcharge the battery.
If your battery discharges significantly lower levels, you can connect it to a charged battery using jumper leads. You will need to connect the smart charger to the discharged battery, and it will start charging instantly. Leave the batteries connected for about 15 minutes, after which you can disconnect them, and the smart charger will continue charging the battery.
It is advisable to charge your battery several times a month regardless of the season. Also, a calcium battery requires a special battery charger, unlike other batteries. You can fully charge a lead-calcium battery with a charger producing a voltage between 16.1 and 16.5 volts.
Using a charger that supplies a voltage below 16.1 will mean that your battery will be partly charged. This means that a car alternator will not charge the battery fully unless it can supply the required voltage for an extended period.
Lead Calcium Battery vs. AGM
These two batteries have some fantastic features that make them suitable for their tasks. A lead-calcium battery is used in cranking, but AGM batteries cannot be used for cranking because they need regular charge and discharge.
AGM batteries are charged at 14.7V, while the lead-calcium batteries are charged at 14.4V. This means that charging a calcium battery using an AGM charger will raise the battery’s temperature. Also, there is a risk of electrolyte boil and a reduction in battery life.
The AGM batteries use glass matt as their electrolyte, which means that it is impossible to get electrolyte spillage. They can be recharged quicker and discharged to a deeper level. When it comes to calcium batteries, you can only discharge to about 80 percent.
The good thing with AGM batteries is that they have a low internal resistance; thus, they can deliver high currents. They also charge five times faster than ordinary batteries. The main advantage of lead-calcium batteries is that they can be used for an extended period before recharging.
Therefore, you can choose any battery, either calcium battery or AGM battery, based on the purpose the battery is intended for. They all work well when they are subjected to suitable conditions and the proper charging and discharging tools.
Lead-calcium Battery Recycling
When it comes to batteries, recycling is one of the critical areas. We all know that the environment needs to be protected from chemicals that include the ones found in batteries. Therefore, you should never dispose of your battery in the environment.
Every nation has a recycling center that deals with different types of batteries. However, not all battery types can be recycled. However, most of the batteries can be taken to collection centers before they are taken to recycling facilities.
Lead is a very harmful substance that can cause adverse effects to human beings, especially children. There have been reports of effects caused by lead recycling factories on the surrounding environment. Therefore, you need not dump your lead battery into the environment.
The lead-calcium batteries can be recycled, and the products that are rescued are sold to lead batteries manufacturers. They are then used to make new batteries and approximately 80 percent of the materials used in the new batteries that we purchase come from recycled batteries.
The lead-calcium batteries are chopped into nickel-sized pieces, and the different components are separated. The plastic in the calcium batteries is mostly polypropylene with a high heat tolerance; thus, it can be recycled. The lead is sold to companies that make new batteries.
