If you keep the drive battery above 20% the 12V will be charged. Yes, I keep mine plugged in but I don't let my drive battery get below 20% overnight.
Thank you. I keep the battery usually above 50% unless I am driving a couple of hours or so.If you keep the drive battery above 20% the 12V will be charged. Yes, I keep mine plugged in but I don't let my drive battery get below 20% overnight.
Remove it, unless it has the auto-off mode. All other dongles will flatten the 12v battery.For all the folks who use a OBDC dongle...do you leave the device plugged in all the time or only when you need it? My concern is that if you leave it plugged in all the time, is it likely to drain the 12v battery?
Yep, I installed a switch but the manufacturer of the switch was not thinking it though and made the cord too short on one side so it is not as convenient as I hoped. So I only turn it on for road trips and even then I did not want the potential of a wear issue from plugging and unplugging so much.Also to note, unless you have a dongle that has a physical connect button then anyone can connect to it.
This is the reason I made the decision to go with a LifePo from the get go... plus the OEM battery fits in my Miata. But another advantage is the low voltage disconnect and "self jump start" that will allow you to throw the contact again.Remove it, unless it has the auto-off mode.

Cycling the 12v battery via the automatic top-up should be avoided, it degrades the lead acid battery chemistry.
GDS official diagnostic software can retrieve detailed 12V battery data 30 days back, including battery drain caused by any aftermarket devices:
