Laptop battery repair, help

Probably (thermal)

Can't read the part number - look for it on google first

I wouldn't. Assuming fairly modern battery it will need monitoring for temperature rise.

You could also try sci.electronics.repair (but have the part no. etc off the device first)

Look on eBay for an old battery which only holds a few minutes of charge. Or tell us which laptop model it is and someone here may have one.

Well, it is a Klixon so a thermal cutout device, almost certainly. Where you would get a quantity of 1 from, I don't know. It is there to stop a fire if the battery overheats. You could short it out but don't blame me if it catches fire!

It's Klixton 10v9K 4MM70B1 I have googled, and couldn't find anything apart from Klixton having discontinued this device.

Thanks I will try that if all else on here fails. Mark

Looks like

Thanks that's useful but they don't seem to have a UK distributor

Try posting to comp.systems.laptops - there are some very knowledeable people there who know all about batteries.

Try these UK guys, they do klixon

Quick heads up - Those cells are Lithium... If the cutout has failed it may be for valid safety related reasons. Replace it by all means, but don't leave it unattended on charge for at least the first few sessions.

All other precautions handling lithium batteries and avoiding burns ... etc...

Just replace it with a non resettable thermal fuse, plenty to choose from in RS, here's one:

You need both.. just put them in series.

It's probably a thermostat, the make - Klixon (clicks on!) is the clue here, there is normally a non- thermal fuse as well, which operates at a higher temperature, say 105deg.C incase the Klixon goes short circuit. I can't seem to find the website , they seem to be owned by Ti these days.

I did email both the US and Europe distributor, the device is discontinued

I have now replaced it with a thermal cut-out and a normal fuse, it now works fine.

Thanks for your and everyone else's help and suggestions.

I?ve found it
