I had 2 incidents with battery tripping.
My Sofirn 14500 tripped so I zapped it with 12v just briefly. It worked in flashlight, stored it away and then no work few weeks later in flashlight.
My Pansonic Eneloop Pro AA went to 0V. It wouldn’t charge again right away. Few hours later put back in charger and it started to charge. Now it’s fully charged and okay! 
Hope this helps.
