  • Brass copper material is more conductive than other materials. If your battery is lithium batteries, you must choose a brass terminal. It is better to keep the same metal for the cell plates and the terminals. But if your battery is lead-acid batteries, I would recommend you chose a lead terminal, because lead is more corrosion resistant to sulfuric acid.
