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

this just a li ion thing?

not always ryobi will not charge hot nicads on above 30 degrees

if you have problems with any batteries try a different charger try again after 30 mins at around 22deg this allows the charger /battery to to reach an optimum charging temp

if you actually look in your "battery charging" section it will normally say don't charge a hot battery after heavy use
it will also say do not try and charge with a very hot or cold charger

ahh right. ive once had an issue where my dewalt charger (yellow model) wouldnt charge a battery. the light flashed faster than normal. half an hour after that it was ok.
