How to Make a 12 Volt 10 Ampere Battery


In this article, we will guide you through the process of making a 12 volt 10 ampere battery. This type of battery is commonly used in various applications such as automotive systems, renewable energy systems, and backup power systems.

Materials Needed

To make a 12 volt 10 ampere battery, you will need the following materials:


  • 12 pieces of 2V 10Ah lead-acid battery cells
  • Alternatively, you can use 6 pieces of 4V 20Ah lead-acid battery cells

Battery Holder

  • A plastic or metal battery holder that can hold 12 cells
  • Alternatively, you can use a wooden or PVC battery holder

Wiring and Connectors

  • 12 AWG wire for connecting the cells
  • Battery terminals and connectors
  • Fuses and fuse holders (optional)


  • Distilled water
  • Sulfuric acid (H2SO4) with a specific gravity of 1.250 to 1.300

Step-by-Step Instructions

Step 1: Prepare the Cells

  • Clean the cells thoroughly with a soft brush and distilled water
  • Make sure the cells are fully charged before assembling the battery

Step 2: Assemble the Cells

  • Place the cells in the battery holder, making sure they are securely held in place
  • Connect the cells in series to achieve a total voltage of 12V
  • Use 12 AWG wire to connect the cells, making sure to connect the positive terminal of one cell to the negative terminal of the next cell

Step 3: Add Electrolyte

  • Mix distilled water and sulfuric acid in a well-ventilated area, following the manufacturer's instructions for the correct ratio
  • Pour the electrolyte mixture into each cell, making sure to fill it to the recommended level

Step 4: Connect the Terminals

  • Connect the positive terminal of the first cell to the positive terminal of the battery
  • Connect the negative terminal of the last cell to the negative terminal of the battery
  • Use battery terminals and connectors to ensure a secure connection

Step 5: Add Fuses (Optional)

  • If you want to add an extra layer of protection to your battery, install fuses and fuse holders

Step 6: Charge the Battery

  • Charge the battery using a 12V 10A charger or a charger with a similar specification
  • Monitor the battery's voltage and current during charging to ensure it is charging correctly

Safety Precautions

  • Always wear protective gear such as gloves and safety glasses when handling batteries and electrolyte
  • Make sure the area is well-ventilated when mixing and pouring the electrolyte
  • Avoid short-circuiting the battery, as it can cause damage or even an explosion


Making a 12 volt 10 ampere battery requires careful attention to detail and adherence to safety precautions. By following these steps, you can create a reliable and efficient battery for your application. Remember to always handle batteries with care and follow proper charging and maintenance procedures to ensure the battery's longevity.
