It's because they now identify as my other half, too hot, too cold.

You'll probably find that only part of the battery is too hot, some vague places will simultaneously be too cold.

🤔

It’s possible.

How long had you had it before it packed in?

No, the batteries weren’t warm; the charger was flashing before a battery had been put into it and when there was one put in, it just continued flashing the same way. 

It’s the only time I’ve had a problem with the charger itself and it will be way out of warranty by now. 

Yeah had it about 3 years before it stopped working. I have a feeling the battery terminals got wet doing work on a rainy day and must have blown it.

I strongly advise you do not try to replace this fuse, it has blown for a reason, if you do try use a very low amp fuse, I tried and the damn thing went bang big time.

Yeah it’s a glass fuse I think it’s 2amp or something and not sure if it’s a slow blow fuse. But not in any hurry to repair it. I just use the slow charger and it’s been fine for at least 2 years. 👍

I read that online. 
I can’t understand why though as the charger and batteries were all in the same place they always have been. 
Thanks for the tip though, I will warm them up and try again. 
👍🏻

Warmed both charger and battery up - no change.

I shall probably end up getting a replacement.

It is a LONG time since i was up to speed with electrical things, but i can tell you that fuses [like MCB's] come in different types according to their "characteristics" So, you can have two fuses of the same current rating, but they will be VERY different.

 

One might be designed so that it is very fast acting and if sensitive to slight overloads [instead of letting them drag on for hours] and another might only be designed to be slow acting and will permit quite high short duration overloads and only really be sensitive to short circuit currents..

 

I too, would not be replaceing the fuse unless i was certain i was replacing like for like. Even then, as you very rightly say, the thing blew for a reason.. Fuses can blow due to age mind..

Is there a flashing light if its got a head ache ?

My QC330 stopped working after 10 months charging 2 batteries a couple of times a week for the summer.

I managed to get it replaced and this unit has now burnt out after 5 months of very light use.

Not impressed
