The Tudor TK620 at a glance

The Tudor TK620 is a battery for cars with Start-Stop: it withstands many more starting and partial-discharge cycles than a conventional battery and powers the electronics every time the engine stops at the lights. The TK620 is designed for cars that switch the engine off at every stop and restart it dozens of times per trip.

At 62 Ah it is the usual size for compact diesels and mid-size petrol saloons. The TK620 belongs to the Tudor TUDOR AGM range. See all Tudor batteries

Before ordering the TK620, check this

  • The TK620 needs 242 × 175 × 190 mm of space (European case size L2): measure it with the hold-down clamp in place.
  • The TK620 has the positive terminal on the right: compare it with your current battery.
  • Capacity of the TK620: 62 Ah; the same as your current battery or slightly more is fine.
  • Check the EN amps on your battery: if it says 680 A or less, the TK620 covers your engine.
  • The TK620 is AGM: it replaces an AGM or an EFB of the same size. You can swap an EFB for an AGM, but not an AGM for an EFB.

Inside the TK620: AGM technology

The TK620 is AGM: the electrolyte is absorbed in glass fibre mats, so it is sealed and spill-proof. Being sealed, the TK620 can be fitted in the boot or under a seat with no risk of spills.
