Size, terminals and hold-down of the Exide EZ850

In terms of format, the Exide EZ850 measures 353 × 175 × 190 mm (length × width × height) and weighs 25.50 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 B13 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 EZ850: Dual EFB range and EFB technology

The EZ850 is part of the Exide Dual EFB range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family.

EFB combines the robustness of the flooded battery with improved plates and separators. The result is a clearly longer service life in vehicles that start and stop constantly.

How to make it last longer

As a service battery, avoid routine discharges below 50% to extend its cycle life. Protect the terminals with dielectric grease and check the fixing: vibration and swell loosen connections.

Manufacturer's warranty

The Exide EZ850 comes with the manufacturer's official warranty against manufacturing defects. Deep discharge from winter lay-up without charging is not covered.
