I have same battery, my is original to the car so going on to 6 years old and still holding very well. you can look up date of the battery on the negative post, on top. first two numbers are weeks and other two year. my is 34 (mid september) 2011.
AGM batteries need slightly different charging algorithm which in my car I can change with IIDTool.

if the battery is totally flat do this:

Got to say that AGM was only ever fitted to the last of the ffrr's 2010_2012, all the rest had either an 019 or 020...

An AGM battery needs a higher charging voltage than a normal battery to get the best out of it... I'm not sure if you can change the voltage with an IID.

Further more, a heads up for those who need more electricity... LR fitted Varta batteries as OEM... but if you buy a silver Varta battery from elsewhere you will save about a third over stealer prices, and they come with a 5 year warranty, AGM only carry 3 year... why pay more for something that isn't suited to the car, and warrantied for 2 less years? It does not compute

And lastly an 020 is 110Ah, it is the largest capacity battery that will directly fit without a crowbar  Yesterday I couldn't spell Engineer... Today I are one!

BBGR, it is the original battery to the car, so , yes I asume that H8HD means AGM.

I had a somewhat similar issue with my RRTDV8 (08 Luxury 3.6). Battery was 18 months old when it failed to start. Can't remember what the warning was but I had the battery & alternator checked by Royal Auto Club (Qld) and Battery World (retail supplier) .. both saying the alternator was testing OK but but the battery was just in need of a charge. The battery was regularly charged every month overnight on a Ctek (7amp). I did as advised and charged the battery again. It was OK for a couple of days but then wouldn't start the car.

I took it back to the supplier and again it couldn't be faulted so I bought a new one and the other was sent back to the manufacturer for testing. Some 6 weeks later I got a call from the supplier saying that after several tests the battery was found to be faulty. They very kindly refunded the money I had paid for the new battery.
