Dremmel is shite, made by Bosch. Much better to get the Milwaukee M12BLROT. It is a very rare thing when I buy or recommend anything American, but in this case they have got it right.

Annoyingly now that I have the M12 platform, I cant see anything else worth getting.

If you can pick them up from Liverpool you are welcome to them. I'm not putting them in the post though!

 

 

I have never been to Liverpool but, tempting as the offer is, a 400 mile round trip is a bit much unless anyone is passing on the way down.

OK, as regarding batteries that are so flat that the charger doesn't recognise them...

 

It's possible to give them enough of a boost by parallel charging them from a good battery that they are brought up enough for the charger to see them, there's lot's of stuff about this on youtube, worth a go for sure, cheers.

 

 

I'll probably get another battery - I only have one, then I can try this, just a bit concerned it could damage a good battery, is that a possibility?

The initial charge for the dead battery will be charging it from the good battery - have to watch out that you don't get a large rush of current, battery to battery. My view would be an old dumb charger with a current limiter to see if that will do the job. Lead acid batteries will tolerate paralleling batteries, not sure with lithium if it generates a large heat - never tried though.

 

 

However much it is annoying though, how many hours are you willing to spend working out a fix and are the value of these hours more than a new battery in the first place - 10 hours of your leisure time = new battery? - add them up, getting advice, sourcing the kit you want, fiddling about to make something work / not work and try again.... though I am enjoying reading the thread to see what fixes there are out there so maybe 'getting advice' doesn't count as much.
