Default accidently discharged my life battery

As stated I accidently fully discharged my 3000ma life battery I use for my receiver/servos, when I put it on my charger it said voltage low and wouldn't charge it so I had to use NiMh to get some voltage in it before switching back to LiFe function, the battery is fairly new maybe 30 flights on it, never been run down before and I charge it after every flying session, so did I kill it? Or is it still good?

They are pretty tolerant, i'd keep an eye on it and if you're really worried make it a bench battery for setup and testing but it's probably fine

How much did the battery cost compared to how much the plane costs is the question I always ask.

I don't think that this is such an issue, right ?

I did the same to a brand new $110 6S LiPo battery once. Was able to recharge by briefly putting the charger in NiMH mode before switching back.

My battery appears to take the same amount of charge as before. But I don't know if it's damaged and could let me down under heavy load. I did fly it once though, and didn't notice anything.

If you cycle it with realistic loads, and it behaves like normal without getting hotter than your other batteries, maybe it has survived? I don't know...

If you have a charger that shows IR of the cells you will know if you killed it or if its good to go

Default I try to destroy my A123 cells that are from when Black & Decker sold them in their o

I run 1 very old pack down to .25 volts sometimes in a vacuum cleaner. It is still at 90 % on all equal cells. A shotgun will kill them. But nothing else that is reasonable.
