Bought the Hitachi 18v cordless drill 3 months ago. I used it back
then and all went well. Yesterday i had to just screw a 1 1/2 screw
into my laundry wooden dryier holder...for one of the legs got loose.
i got as far into with the drill till about a 3/8 of an inch of the
screw. I sort of pushed the drill to complete it, but it could not do
so, so i had to finish it with a screwdriver. I then tried to run the
drill and it would not start...The battery was pratically full when I
stopped using it 3 months ago. The manual says to recharge it again.
No timetable for how long. Anyhow I did, the red light came on and
waited about an hour or so when the red light started to flicker on
and off...so i presumed that *the charge was complete, of course the
manual doesn't tell you time, color or whatever. OK, its working
again...is this typical of these batteries? Are they that sensitive
just to try and screw in one screw? I called Hitatchi support and said
it was normal.

There is a circuit in the battery pack that disconnects the battery
when the voltage gets too low. This is so you don't ruin the battery
by over-discharging it. Lithium batteries do not handle any abuse at
all.

Lithium batteries do discharge over time, but not nearly as much as
NiCds. On the other hand, NiCd batteries can be abused until the cows
come home.

Go back and re-read your damn instructions again, and this time read
the ENGLISH ones... It says how the battery charger is supposed to
work.
