I'd be happy to help translate the text, but I notice you've only provided: "Quest 1 / Project Name : Battery Keeper" This appears to be a header or title rather than body content to translate. "Battery Keeper" is already in English, and "Quest 1 / Project Name :" are typically labels that remain unchanged. Could you please provide the Korean content that needs to be translated into English? Once you share the actual Korean text, I'll translate it following the rules you've specified (preserving HTML, technical terminology, product names, etc.).
