Battery Tender vs Trickle charger

SouthArk370Z · 06-25-2020, 04:30 PM

I wouldn't disconnect the battery from the car as you will lose tuning params and possibly radio presets. You might also need to do a auto-window reset. And the emissions system will reset to a not-ready state.

But none of that is a big deal: the ECM will relearn the tuning after after 15-20 minutes; reentering the radio presets isn't all that difficult; the window reset takes 30 seconds max; unless you plan on doing an emissions test right away it's not a problem - system will be ready after a few drive cycles.
But why have to do any of that when you can just leave the system hot?

I've never disconnected my battery since 2011 when using the Battery Tender. Still have the oem battery.
