Why choose the Exide EA406

Check before ordering

• ✓ Measure the space available: the case takes up 187 × 127 × 220 mm, and a few millimetres too many can stop the hold-down from closing.
• ✓ Terminal layout: positive on the right-hand side. If your original is the mirror image, choose another reference rather than stretching the leads.
• ✓ Rated 40Ah: check that the charger or alternator in your system can refill a battery of that capacity in reasonable time.

Installation and maintenance tips

Picture a dark January morning: the engine turns slowly, coughs and gives up. A memory saver plugged into the 12-volt socket keeps radio codes and window settings alive during the swap. Interior lights that fade when the starter turns are another hint.
