Battery Tender Use

SouthArk370Z

It depends on the state of charge when you started, condition of the battery, and how fast your tender will charge. If the charge was low when you started and the tender doesn't charge very fast (I thinks that's true by definition, but depends on the make/model and who wrote the ad copy), I wouldn't be too surprised if it took a few days.

Edit: I'd trying charging the battery with a "real" charger and then see if the tender is happy.

Edit 2: If the battery is in the car, the parasitic load of the control module may be fooling the tender.
