I'm on the verge of ordering the CTEK CT5 charger which has the lower output voltage (MB handbook stipulates a maximum charging voltage of 14.8V) and is designed for start / stop batteries but can be used on standard units. There seems to be many conflicting ideas on whether you need to disconnect the battery or charge it in situ connected. My MB indy recommends disconnecting although CTEK confirm you can safely charge with it connected.
To confuse matters further I had to take the XC60 to the Volvo dealership this morning. Whilst there I took the opportunity to ask them about charging the battery as I frequently get a 'low battery charge' light after listening to the radio with the engine off (apparently a common Volvo problem). They advised disconnecting the batterybefore charging! Does anyone (indies included) have a definitive answer to this? Access to the battery on the W203 is a pain as you have to remove the filter housing to the heater fan as is the Volvo with various bits of trim / panels you have to remove.
