    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 :D

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