This might be a very silly question but here goes.
Been looking at one of these to replace an ageing smaller model. Upon looking at the online instructions and spec I note that the spec for the MXS 5.0 shows the voltage in desulphation mode is well over 15 volts, which I'm worried might be high enough to damage the car electronics and I don't want to disconnect. Ok, so i never use that mode except that it seems the charger can commence charging on the desulphation cycle in any mode.
So, simple question. Is it ok to use a MXS 5.0 on any modern Merc without disconnecting the battery first ?
