Recycling Used Lead-Acid Auto Batteries

Recycling used lead-acid auto batteries is important because of the nature of their composition and uses. Furthermore, people use lead-acid batteries as backup power supplies and to power things like:

• Automobiles
• Electric scooters
• Electric wheelchairs, etc.

The acid provides the electrochemical effect that powers these machines. Similar to every other battery or power source, the lead-acid auto batteries deplete or dilute and the chemicals start to lose their efficiency due to:

• Loss of water
• Overcharging
• Sulfation

Because of the toxicity of the lead-acid batteries, most countries have prohibited the indiscriminate disposal of them, for instance, incinerating or dumping, and have highly suggested recycling used lead-acid auto batteries.

Recycling used lead-acid auto batteries must be done cautiously and with full mindfulness, preferably in a controlled environment a long way from residential areas. So, what are the steps involved?

1. First of all, recycling companies collect dead or used lead-acid auto batteries for battery depositories.
2. The recycling company then neutralizes the acids. Moreover, they present a base that subdues the corrosiveness (toxicity) of the acid so it can be securely disposed of.
3. A hammer mill shatters the battery or breaks it apart. This procedure refers to as hammering
4. Then, place broken pieces in a vat, so that the lead plates and heavy materials sink to the bottom while the plastic floats.
5. They transport the polypropylene plastics into a plastic recycler to melt and refine them.
6. Cleaning the lead plates and heating them in furnaces to melt them. After this, cast the molten lead into an ingot mold. A few minutes later, the impurities float to the top of the cast and they scrape them away.
7. Finally, they remelt the pure ingot casts and use them in new batteries.
