Inside the TB621: lead-acid technology

Inside, the TB621 is classic lead-acid: liquid electrolyte and lead plates. It is a robust, well-known technology with a good capacity-to-price ratio, and still the basis of most cars, trucks and traction equipment.

Check this before ordering the Tudor TB621

  • If your car has Start-Stop, the TB621 is not the right one: it needs an EFB or an AGM.
  • Check the EN amps on your battery: if it says 540 A or less, the TB621 covers your engine.
  • Capacity of the TB621: 62 Ah; the same as your current battery or slightly more is fine.
  • Polarity of the TB621: positive terminal on the left (if yours has it on the other side, the cables will not reach).
  • Measure the space: the TB621 takes up 242 × 175 × 190 mm (European case size L2).
