Can you charge through the OBD port?
As long as the charger is a reasonable wattage (not 100W!), you should be just fine. The OBD port can handle 2-5W just fine.
Does obd2 port drain battery?
Battery Drain So a poorly designed OBD device, when left plugged into the OBD port, might completely drain your battery. Worse still, if a device is not carefully designed, it can turn on your ECU even while the car is not running, draining your battery even faster.
What is the difference between an OBD reader and scanner?
Both code readers and scan tools interface with a car’s on-board computer or diagnostic system to identify or troubleshoot problems. A code reader is a simplified version of a scan tool, but it’s only capable of performing basic scans of trouble codes.
Can a trickle charger charge a car battery?
I often had battery issues with my old car because I used the car so little and it gets very cold where I live. Since the car is brand new, and the battery is probably on the dead side since the car has not been used, I purchased a 12V battery charger (trickle charger/maintainer). It has 2 charging modes 0,75 amps and 2 amp.
Is there an OBD port for a car?
There’s still not much on the market for an OBD-II port that isn’t a diagnostic device or some sort of engine computer hack. Nothing that would normally be plugged in constantly. Maybe since cars are removing their cigar lighters the OBD will be the new port people plug their mini-fans and other gadgets into.
How does an OBD-2 diagnostic device work?
You plug in the diagnostics device and it measures the battery voltage through it – which would be ambiguous if there was some logic or relay to turn it on first because that might then be broken. Right. There’s still not much on the market for an OBD-II port that isn’t a diagnostic device or some sort of engine computer hack.
Do you have to unhook the battery to charge it?
In the owner’s manual, it says that the battery should be unhooked to charge it to avoid damaging the electronic equipment. I was wondering if this is actually necessary since jumping the car does not require this (I would assume that jumping the car puts much more stress on the electronics than using a dedicated charger). What do you guys think?
