MG ZR Battery - How Many Amps? (not Volts)

[im]

Hi PH'ers

My son has an MG ZR and is trying to get a 2nd hand battery from a breakers yard who've said they have some but need to know the amps his current battery is rated for.

As this info isn't on the battery itself and he's mislaid the handbook I wondered if anyone here might know.

For once, Goggle has not been our friend.

Frankly, I only ever recall the Volts being relevent but hey, I'm no mechanic.

Any help greatly appreciated.
