Watch out

Why people pick it

  • Supports all common lead-acid battery types: flooded, AGM, gel, EFB and VRLA, per TOPDON
  • Recognizes nine battery standards including CCA, SAE, DIN, IEC, EN and JIS
  • Clamp-powered, so there is no internal battery to charge or replace, and it carries a 2-year warranty
