a timley reminder when charging batteries

[big-all]

i was working in the workshop this evening routing a moulding on the edge off a dresser top
the li-ion battery started pulsing so put it on charge
10 mins later noticed the red light ouch 3 attempts at resetting no go

then i thought take the spare charger indoors plugged it in the same

back out the worksop to finish assembly off dresser top
then it dawned on me i had been working quite hard and hadnt noticed the temperature had dropped to below 9 degrees

ryobi batteries and chargers along with other manufacturers will not charge hot batteries until they cool or wont charge if the temperature is too cold or too hot

so remember leave your battery and charger at room temperature for 30 mins iff it wont charge to warm up/cool down before deciding its failed

Modern technology is not without it's faults, sometimes it's backward progress, cfl lamps over incandescent, are another example.

Here Here! The new bulbs, say 11W=60W (my arse!), trying to read under them, and it's like I need glasses, and they take ages to get bright. Can't get the right fitment, as one has just blown, they give me a headache, due to a HF flicker?

And I was thinking earlier, the old style bulbs give out a certain amount of heat, so in theory, heating systems were set lower.

But maybe the way forward is to uninvent technology, as automation and efficiency has always put people out of work. So bad technology vs uninvented technology?

with low energy lighting i always say go for a ratio off 4 to 1 so you need 15w to = a normal 60w bulb
modern low energy light up fairly instantly starting at about 80%-90% and full brightness within a min. or so

iff you take an underpowered bulb and knock off 20% your only on half the brightness you need so try a modern low energy bulb and go for the 4/1 ratio

There's also different white 'temperatures'...I quite like the 6400K daylight bulbs but some people find these are too cold, they put out a good amount of light though

It could be the noise... Despite bashing my eardrums with loud music and powertools for many years, I can still hear bird-scarers, switch-mode psu's and... CFLs.

I only noticed it after replacing all the incandescents in my house. Philips too, not cheap unbranded ones.

To be fair, it's only about 50% of them that give off the noise and it is intermittent, but it is very annoying when it's there. Probably a noisy capacitor somewhere in the electronics of it.

I wonder if the people who get ebay-tastic blue-tinged HID kits for their cars also buy blue-tinged CFLs?

Again, another 2 post that I'd like to reply to but don't know how..sob!

My main light in the living room is x5 candle style bulbs @ 40W, but have been replaced, when the origional failed at the specs above, and x2 were faulty on install, headaches, bad eyes, can't see a thing, now down to x2 flo tubes, 1 failed flo tube, 2 failed traditional candle stylee bulb.

When I'm lied in bed, I hear that constant low hum, and I've got in the habit of completely switching off everything near the bed, indeed getting up in the night and switching more off....But where I live, we have constant power cuts, and I believe, that the streetlighting is causing the constant humming. I believe it's got to the point where I get excessive earwax build up, that causes tinnitus(?) whistling in the ear. I know a tuned coil in a radio set could become unbalanced, and cause a high pitched whine, cured with nail varnish, but this contant hum?
