Your questions answered

How do I search for a battery by brand and code?

Is this battery easy to lift?

25.5 kg is the listed weight. For larger batteries, a second pair of hands makes fitting safer.

Can a battery be stored before use?

Yes, but all batteries self-discharge slowly. Check the voltage every few months and recharge if needed.

Can you give me the size and weight of this battery?

The case measures 197 × 170 × 342.5 mm and the battery weighs 25.5 kg. Check both against your tray and the hold-down before ordering, and lift it with care.

Before you order: a quick checklist

✓ 400Ah sets how long the battery can power things with the engine off.
✓ This reference uses AGM. If your current battery has a different technology printed on it, find out why before switching.
✓ Grab a tape measure: 197 × 170 × 342.5 mm is what this case needs.

What AGM means for you

Gas produced during charging recombines inside an AGM battery, so it loses almost no water. Because nothing can spill, AGM batteries can live inside a cabin, a boot or under a seat. If the original was AGM, the replacement should be AGM too.
