Is my battery tender dead? It just keeps going 'click click' every few seconds and doesn’t leave position 2. I connect it to the car, press the reset butt, but this is what keeps happening.

Here's a short video of how it's acting if the attachment doesn't work: https://streamable.com/lgvcee

 

@981WC ,
How is it attached to the vehicle, can you show us ?

981WC,

One of my battery maintainers does that every now and then also. Mine is not the Bentley version, but the CTEK.7002 which seems to be the equivalent version. When mine does it, I disconnect it from the car and the outlet for a few hours and also drive the car some. This usually "resets" the maintainer it goes back to normal. Sometimes it takes a couple of rounds of doing this. I also have two of these hooked up, one per battery and switch them up. Sometimes it takes a couple of times, but it's always gone back to normal.

 

that worked! Thank you Mars!

 

I've used CTEK chargers since 1990's, I think I have five or six now and unfortunately I'm very familiar with their quirks. By far the most common cause for unexplained behavior, lights blinking back and forth, charging being interrupted or not starting at all is a bad connection to the battery. This can be caused by oxidation of the connectors or heat damage. I just replaced a burnt plug on one, after weeks of wondering why the LEDs keep switching between empty/half/full and batteries aren't charged even overnight.

 

Battery Tender products are bullet proof, been using them for 30+ years.

 

Lifetime warranty too. I had one fail once so I called them & they sent a replacement. All I had to do was email a picture showing that I cut the cables off flush to the unit.
