Need alternate batteries or charger for screwdriver

[zaphod]

about this trickle charge thing.. its dosnt happen..

i deliberately left a bunch of batteries in the nano chargers overnight for around twenty hours..

they came off at around 4.22 volts exactly the same as if they had been removed immediately after the led going green..

Well I always was skeptical about the so-called tickle charge discussion of e-cig batteries.. As far as I know LiIon batteries not only dont need this but on the oposite - they MUST not be overcharged... cause they like to explode
this is not NiMh I read about a boy whose pocked was burned by PSP-s battery... these thing go off pretty easily
I can feel every single LiIon device getting pretty hot with hard use... for example my Qtek S200 windows phone, the Holux 235 GPS, My iPhone 3G and so on... they all get pretty hot and pretty fast same thing when I charge them ...

i have repeated said this leave on ages just to make sure stuff is nonsense zaphod.. but the myth refuses to go away.. not helped by a certain well liked brand name spouting it in their user instructions..

the good old memory myth is showing signs of going away but not the trickle charge one..
