Oops may have killed my batteries...

I used my Vivitar 285HV on Friday and forgot to switch it off before I packed it away. Took the batteries (4 x AA eneloops) out to charge this morning and... they didn't register on the charger.

I put them on the Sanyo dumb charger for about half an hour to raise the voltage so the smart charger (Ansmann Energy16) could see them, so hopefully all is good.

Has anyone fully discharged their Eneloops before and noticed any issues after? I know NiMH cells are not designed for deep discharge.

You should have no issues fully discharging a NiMh battery. If youre smart charger isnt reading them Id suspect the smart charger. Upgrade and pick yourself up a Maha C-9000. I have many times done discharge/recharge cycles with all of my Eneloops in my Maha C-9000 and they all work great!

I was following the advice from this blog post and it seems the batteries have taken a full charge. I really should have pulled the voltmeter out to see what the cells were reading in their discharged state.

I take it from your post that the Maha recognizes completely drained cells too?
