leaving v2 plugged in

[BAD BOB]

will leaving the v2 thing plugged in to the OBD2 port will it kill the battery? if so how long will it take?

Hi BB,

Yes it will (a few days, maybe more), unless you power it off (the key with the universal power switch symbol on it).

It is not recommended to leave the V2 connected for long periods with the engine switched off.
Depending on the power rating, size and condition of the battery you may be able to leave FlashScan connected overnight or even for a few days at a time. But eventually it will drain the battery.
