The CTEK has surge protection built in.pvr said:That is not true though - the front connector (+) has surge protection on it, the battery obviously not.
What you are on about is more to do with jump starting and using a booster to start the car and yes your dead right with using the front connecters, but the OP is on about charging .pvr said:But they do / can fail. I would rather use the car's own electrical fail safe protection than bypass that.
+1 - with charging, it makes no difference how you connect to the battery. In fact with intelligent chargers such at the CTEK, having any additional car 'protection' in the way may make it more difficult for the charger to gauge the state/condition of the battery2dogs said:What you are on about is more to do with jump starting and using a booster to start the car and yes your dead right with using the front connecters, but the OP is on about charging .pvr said:But they do / can fail.

And we are not offcially "recharging" the battery, we are keeping it steady at full charge. Huge difference.
Good point though.

I don't know how much more specific the manufacturer can be?

No worries on that front !
Just a guess here, but I would say that you don't use the under bonnet pins?![]()
