Hanatora

[SoooBueno]

I just purchased the Hanatora 5-in-1 charger. Connected all 4 batteries, but it just keeps cycling through the 4 stations flashing “checking”. My batteries have been sitting for a couple years. Could my batteries be bad? This is for my Mavic Air artic white.

Try charging them one at a time on the original charger.

For sure. That's the most common way to kill batteries.

Try what @mobilehomer recommended to rule out a faulty charger.

@msinger I know to wake the batteries from hibernation usually requires the use of the original charger, do batteries that have been sitting for a long time go back into hibernation mode at some point or do they just eventually go bad?
Thanks

they will of course eventually drain completely and that will eventually be their downfall so yeah...nothing to do but try the original charger and see if it brings them back to life.

Right. There is no such hibernation feature that will prevent DJI batteries from completely depleting.

This is interesting, but from what I noticed, once I flew my Mavic Air 2 to 0%, and after landing it, immediately it turned off automatically, and the battery wouldn't flash when clicked, I plugged it to charging (original charger) and it would still not do anything, but after a while (about 15 minutes) it started charging and works perfectly to this day.

Do the same test again, but let the battery sit for 2 years before attempting to charge it. I don't think the results will be the same.

That's true. I missed the fact that the batteries were sitting for that long.

My batteries have been sitting for a couple years.

And completely discharged too? Yeah, probably dead batteries then.

Still, try leaving them for a few hours on the original charger, without the hub, the battery directly connected to the charger, maybe there's still a chance...

When I put my batteries (which are cool either hours after using or the next day after using) on the Hanatora charger in the off state, with the charger unplugged and then plug the charger in (red main led on charger) the batteries just blink with one light at a fast blink and charger displays "checking"

I have to turn them on before installing on the charger for them to charge.

From what I read here this is not normal.
