I've just bought a CTEK MXS 5.0 battery charger and since I'm going away for ten days tomorrow and have been doing lots of short journeys recently I've connected it up. My car still has the original battery from 2012 so I thought I'd give it a recondition.

Only the instructions are really confusing and badly worded as to whether the recon mode is suitable for AGM batteries, and online isn't much better. Recon mode only appears to be a no-no as that appears to be for older type batteries but what's confusing me is that my charger has an "AGM Recon" mode. The manual, however, suggests that these basically treat the battery in the same way, giving it the same level of voltage.

I've read loads of old forum posts about recon mode and battery charging in general but nothing I could find deals specifically with "AGM recon" on relatively newish BMWs, and I don't want to come back from holiday to find I've killed my car battery so I'd really appreciate any knowledgeable advice. If it's the wrong thing to do I can switch it off recon mode tonight or first thing before we go to the airport.

Thanks in advance!
