What voltage and amperage are typically required for charging semi truck batteries?

I’m working on a project involving the maintenance of semi trucks and need to understand the specifics of their battery charging systems. I’ve been tasked with ensuring the batteries are properly charged, but I’m unsure about the technical requirements. Could someone clarify what voltage and amperage are typically required for charging semi truck batteries? Any details or recommendations would be greatly appreciated. Thanks!

Semi truck batteries are usually 12 volts. Charging typically requires 20 to 100 amps, depending on battery size and charging speed. Higher amps charge faster but may cause overheating. Always check the battery’s specifications and use modern systems for safe, efficient charging.
