Just got a CTEK 3300 charger...plugged it in to the cig lighter....midldle light on top for charging mode was orange for a few hours...went out to check it...charged light was on solid green but charging light was blinking orange rapidly...is it working correctly? Couldn't find anything in the manual to see whether this means it's in maintenance mode and all is good??? I unplugged the cig lighter and plugged it back in...the charging mode light came back on in solid orange. Any advice would be appreciated!

All the best,
Michael

 

For most chargers that means at 80+ percent of a full charge. Should go solid soon if that's the case.

 

When I plug in my Ctek, the blinking light tells me the state of charge of my battery. It's usually orange. As soon as I choose my method of charging ( motocycle, battery, gel) the blinking light turns green right away and the top light works from orange to green or goes to green right away. I never had the blinking light stay orange after choosing mode it always blinks green then.

 

I found this under CTEK FAQ on their web site, not sure if it is the same issue, see * Fault at the bottom.

Q. When I switch on the charger, the diodes flash alternately. What does this mean?
A. There may be several reasons: Poor contact. Move the connections a little. Check that Comfort Connect (or the white plastic contact on the charger lead) is properly assembled. Sulphated battery, see Charger Academy – Desulphation, is a likely cause and where CTEK chargers have an exclusive feature. A sulphated battery has a layer of insulating lead sulphate on the inside. It does not cover the inside fully as you can still detect voltage across the battery. What happens is that the charger sends out pulses of energy until the battery starts to accept the charge. Batteries that “will not accept a charge” can often be revived using this method. Let the battery charge for one hour. If the charger still flashes, this indicates that the battery is dead and needs to be replaced. If the yellow or green lamp lights, you have activated the battery and it will probably work, but it is nevertheless at the end of its service life. The MULTI US 7000, MULTI US 25000 and MULTI XT 14000 models alert the charger if desulphation has been in progress for more than four hours. Let it charge for a couple of days to boost the power, while being aware at the same time that the battery will soon be dead. There are coarse sulphate crystals which no charger in the world can break down.
* Fault in battery cell. If the battery started charging in the correct way, with the orange lamp, and then starts flashing, this is due to a break somewhere. The most likely explanation is that the connection has simply fallen off, but it could also be a break inside the battery. Turn the charger to OFF/STANDBY and then back to charge. If there is a break, the charge will not start.
