K2 Energy K2B24V10EB not charging

[Dave (Boog)]

I have two K2 energy 24 volt batteries. One reads 13.8 and the other 14.6 volts. I’m trying to charge these up but ny charger won’t charge them. I’ve tried them individually and in series but no luck.
These are lifepo4 batteries. Has anyone had any luck charging batteries that have been this depleted?
I’ve thought about trying to hook them up to a power supply, to see if they will take a charge.
Any ideas how to revive them or should i just throw them away?

Its been my experience from bench testing with 18650 LFP cells that once they are discharged below their damage threshold, somewhere around 2 volts, they are finished. You probably should try and recycle or dispose of them properly rather than throw li batteries in the regular trash.

I’m going to play around with different ways of charging them. And by throw them out, i don’t mean in the trash. I of course will recycle them.
