Question 1

Once switched on & mode selected, if there is a power cut, will the unit remember and continue automatically on the resumption of Mains power?

Accepted Answer

The charger remembers the Mode set with the button, but starts at the first step of the charging process for that Mode after a break in the power supply.

Question 2

How does this charger connect to the mains? I can't see a mains lead.

Accepted Answer

The cable on the left in the picture is about 2 metres long ending in a 3-pin 13A plug.  That on the right ends in a mini line connector which mates with either the crocodile-clip or ring-terminal extensions shown (and included).  A "cigarette lighter connector" (to charge through the 12V 'lighter' socket) is also available as is a rubber bumper.  I bought these with the charger.  My car's fuse panel can be configured to make the lighter socket permanently live so the charger can be left under the front passenger seat, invisibly topping up the charge when the car stands unused for days on end.  The rubber bumper fits around the charger's plastic case, both protecting it against knocks and making it far less likely to slide off front wing, top of the engine or whatever.  A brilliant bit of kit.  Its 5A rating may look pretty modest but unlike simple chargers whose output drops sharply once the battery starts to take some charge, the CTEK pumps out a full 5A for the whole of the bulk charge phase; an overnight charge of a completely 'flat' will give you a fully (not partly) charged and reconditioned battery and it can be left connected for months if necessary.  It's worth looking at the full specification on CTEK's own website.

Question 3

What is the mains voltage input range

Accepted Answer

220 - 240v

Question 4

My son has just bought a 125cc motorbike. would the battery connectors on the CTEK charger be small enough to fit onto a bike battery?

Accepted Answer

Yes it will charge a car and bike. It has a dedicated bike mode which lowers the charging rate.
