Small battery 2014 on.
Has anybody charged the small battery with a ctek? Would connecting the charger be similar to the main battery?
Thanks in advance.

I've been charging mine with an MXS10. Connected directly to the battery, as the -ve from that battery is connected directly to the chassis - unlike the main cranking battery which has the BMS connected.
Seems to work fine If anyone knows the spec of the Aux battery or it's part number, I'd like to know, as mine seems pretty poor at holding a decent charge.D4 MY14 XXV - RLD/IID BT

Just found my TOPIx printout of the Secondary Battery spec. It's a 12v 14Ahr 200CCA AGM battery, so i'd suggest using the AGM setting on your CTEK. It's SoC is measured by the GWM, so connecting directly to the battery terminals is fine D4 MY14 XXV - RLD/IID BT
