MG 5 LR 12v battery replacement

[Rayz]

What is the best type of battery to. Replace on My MG5 EV LR it's maintenance free type 075 12v 55 amp Could do with a bigger amperage?

The amperage is to start the car surely? No crank to turn so high amperage isn't needed?
Then the 400v HV battery kicks in.

As you are aware the early MG models and ZS and the MG5;use 12v halogen headlamps which take 8 amp alone let alone DVD , Radio, heaters, Aircon which take even more. They all work off the 12v battery. The DC-Dc rectifier is voltage controlled not amperage like the standard on Petrol and diesel so that's why the battery is 55amp type. Thanks

I have a 2021 sr mg5 with halogen headlights, in full beam they consume 1amp.
Not even that as the dash shows 1amp with them on or off.
Osram night breakers 150% are only 73watts which would be 6amp
