• 𝗧𝗘𝗦𝗧 𝗕𝗘𝗙𝗢𝗥𝗘 𝗬𝗢𝗨 𝗖𝗛𝗔𝗥𝗚𝗘 𝗢𝗥 𝗥𝗘𝗣𝗟𝗔𝗖𝗘 — When your vehicle is slow to start or will not start, do not guess whether the battery needs charging or replacement. Check battery health, charge level, cranking performance, and alternator output directly on the screen. Clear results help you identify a weak battery, low starting power, or a charging-system issue, then choose the right next step: charge, repair, or replace.
