Hi

I have an Eltek Valere Multicharger 900, it’s a 12V automotive battery charger. And basically it wont charge anything, it just resets and says no clamp contact. I would like to repair it.
I’ve taken it apart and everything looks ok apart from what I believe to be a capacitor has melted. I’d like some help to identity the component so I can replace it and test.

It has 09 printed on top. From what I can make out, it says C291 or C2911 on the side with 58V and some text like ‘TOE’ but it’s melted.

Thanks in advance CE4AB5BD-8BA4-4EC9-8150-96F24B7761DA.jpeg2F263A53-5984-413C-A420-827F72C392E6.jpegDB623A98-B074-49E8-B394-21A2B65F3E94.jpeg5189B5A1-6FB3-4147-98A1-F5F4D3220591.jpegFB04892D-20D5-46A1-B079-3414A48BFF87.jpeg

That blue box originally had a clear plastic lid so I don't think it is (was) a capacitor.
I think it was either a relay or, more likely, a thermal trip of some sort.

Thanks for the replies
From underneath it’s a 2 pin component with each pin around 7-8mm long so a thermal trip or fuse would make some sense.
Any ideas of the name or manufacturer of it?

Thank you very much!
It looks like the fuse is soldered onto the PCB from underneath.
We can charge batteries with over 100A, I can only assume there was an issue and it’s blew the fuse.
I hope the issue was with the battery that blew it and not an issue internally with the charger.
