I would've thought the charger would reach absorption (14.4 - 15V (AGM)) after just a couple hours if the battery already had 12.4V (approx. 75% charge level). 75% is usually about where the charger goes from bulk charge to absorption, where it stays until approx. 90% charge level and goes into float charge - 13.6V. 2007 L322 3.6 TDV8 Stornoway

CTEK MXS10 is brilliant. Use it on 3 different cars and just fit the quick connect leads to them all. I have a Bentley that spends weeks on charge with no problems 2015 L405 SDV8 Autobiography

I have mine on a lowly Ctek MXS 3.6 and it's managing just fine to keep the battery topped up while I am awaiting delivery of a new starter motor. Current: FF Westminster money pit

Had an MSX7 which combusted itself when charging a caravan battery.......

I now have a MSX10 which is currently charging the battery on my M3, which it comfortably did overnight to full charge, and its now on trickle so im not left stranded at Tesco like I was last night! There is nothing that can't be fixed with a hammer😜😜

NmJ,
I wish you hadn’t said that about “combustion “, because I am now on holiday and mine is plugged in to a CTEK 5
Having said that, I have done it several times in past years.

I've used a ctek 5 for months at a time over several years with no trouble. On my previous L322 it was connected via a permanently live cig socket and now in my current one through the towing electrics.  2012 5.0L S/C

Cheers Nomad,
I will rest better for the next 4weeks
I have left both B.B and my previous Td6 many times connected to a trickle charger.
