Hi fellow DRC 18 owners.
I have now noticed on numerous occasions that when I pull my DRC18 out of the Systainer the battery is empty.
After few first times I though that I just forgot to load it, but then I started to take note on the matter and became convinced that this is not the case.
After latest time (few days back) it had happened again (it had been in the box for two weeks without use) I put the battery on the charger and it seems that battery has been permanently(?) damaged by what I assumed was constant drainage on the battery.
Battery would not charge to full anymore because after charging it it was still blinking 'not full' when connected to the Drill.
So I thought to investigate and wired the battery with jump wires into the drill and hooked my multimeter amperage usage measurement to the drill.
At first it seemed fine. I press the trigger slightly and it goes from 0mA into 'awake' mode and starts sucking 100mA from the battery.
If I press it enough to make the motor spin it will take up to 1.23A (no load).
After releasing the trigger and while of inactivity it drops from ~100mA to 0mA (about 10 seconds or so), good this is what I would have expected.
However in some situations it just stays at 100mA and does not go down. I think this is what has been draining the batteries (and possibly killed one of them).
Has anyone else experienced this? it seems to be somehow connected to the 'forwards/backwards' switch.
if I swap it from one position to another the amperage usage drops from 97.8mA to 96.4mA and then sometimes after a while to zero (which is what I would expect)
Anyone else here with similar battery draining problems on DRC18?
I can demo this rather easily when I take the drill to the maintenance, but it would be nice to know if I am alone with my problem or is it more common.
I hope they can fix this as I like the drill otherwise quite a bit (the quadrive is handy for my applications)
