CT200h 12V auxiliary battery replacement — AGM or EFB?

My 2013 CT200h wouldn't start this morning: completely dead, no lights, no response. Breakdown came out and jump started it, and the low battery warning came up on the display confirming it needs replacing.

The battery sits enclosed in the boot so I've been told to avoid standard flooded batteries. I'm planning to get an AGM but wanted to check:

  1. Is AGM definitely the right choice over EFB for the CT200h?
  2. Any specific brands to recommend or avoid in the UK?
  3. The spec I'm looking at is 12V 45Ah AGM (S46B24R) — does that sound right?

Thanks in advance!
