Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 9.30 kg, 3 terminals and B01 hold-down.

The Deta DA406: Senator3 range and conventional lead-acid technology

The DA406 is part of the Deta Senator3 range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family.

The conventional lead-acid battery remains the most widespread technology thanks to its balance of capacity, cranking current and price. Well maintained and kept charged, it offers years of reliable service in vehicles without Start-Stop.

Size, terminals and hold-down of the Deta DA406

The Deta DA406 is made in the 187 × 127 × 220 mm format and weighs 9.30 kg. The positive terminal on the right decides which side the cables end up on: it is the detail that causes most buying mistakes, so check it before ordering. It uses a B01 hold-down and 3 terminals, the system that anchors and connects it in the vehicle. Before replacing it, measure your current battery tray: if all three dimensions and the terminal positions match, the swap is direct and needs no adapters.
