What the Exide ER850 is for

On board, the Exide ER850 provides 180 Ah with a case reinforced against vibration and swell. Keep the terminals clean and protected from salt humidity. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 46.10 kg, EN taper post terminals and B0 hold-down.

Size, terminals and hold-down of the Exide ER850

The Exide ER850 is made in the 513 × 223 × 223 mm format and weighs 46.10 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 B0 hold-down and EN taper post 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.

The Exide ER850: Marina Dual Er range and conventional lead-acid technology

The Marina Dual Er is the Exide range the ER850 belongs to: it shares the same construction and quality criteria with the rest of the series, and varies in capacity and format to suit each vehicle.

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.
