Car battery Deta DB357 Power 35Ah 240A 12V

The Deta DB357 car battery is rated at 12 V, 35 Ah and 240 A of cold cranking current (EN) from the Power range, and is designed for passenger cars with conventional starting, without a Start-Stop system. Measuring 187 × 127 × 220 mm and the positive terminal on the left, it is the direct replacement for cars fitted from the factory with a 35 Ah battery of this format.

• Good balance of capacity, cranking power and price.
• Stable voltage for the vehicle electronics (ECU, sensors, climate control).
• Low self-discharge: copes with long stops without losing charge.
• Designed to last several years under normal daily use.

Dimensions, polarity and mounting

In terms of format, the Deta DB357 measures 187 × 127 × 220 mm (length × width × height) and weighs 8.90 kg. The positive terminal on the left 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 B00 hold-down, 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.

What the Deta DB357 is for

The Deta DB357 covers the needs of passenger cars with conventional starting, without a Start-Stop system: reliable starting, stable voltage for the electronics and a service life of several years in daily use. Check that it matches your current battery in size and terminal position. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 8.90 kg and B00 hold-down.

The Deta DB357: Power range and conventional lead-acid technology

Within the Deta catalogue, the Power series groups the references designed for this use. The DB357 is the 35 Ah model of that family, with the same performance as its siblings in other sizes.

In a conventional battery the electrolyte is liquid and the lead plates are immersed in it. It is a mature, economical and easily recycled technology, ideal for starting vehicles in normal use.

What Deta does differently

Deta combines German engineering with Exide's industrial capacity. Its Power, Senator and PowerPRO series cover everything from urban cars to construction machinery. All the Deta batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty.

Warranty and coverage

The Deta DB357 comes with the manufacturer's official warranty against manufacturing defects; the exact period is stated in the brand's conditions. If it fails through a defect within the period, we replace it free of charge.

Care and maintenance

In normal daily use the alternator keeps the battery charged; if the car stands for weeks, a maintenance charge once a month prevents deep discharge. Avoid leaving lights or accessories on with the engine off: most batteries fail not through defects but through repeated deep discharges.

Delivery times and returns
