Tenergy 10,000mAh battery self discharging too fast?

A few weeks ago I bought 4 Tenergy 10,000mAh batteries based on posts I read at this forum.

But it seems they self discharge really fast.

I charged one today fully to 1.42v…at around 4:00 this afternoon.

8 hours later, it’s down to 1.36v and I think by morning it will be down to about 1.32v

If it stabilizes at 1.30v – 1.32v, is that acceptable self discharge for that kind of battery over a 24hr period or less?

In my experience a 1.32 to 1.36 resting voltage is normal.

Thanks tatasal.

It’s only down to 1.35v after sitting overnight. Seems the self discharge already slowed down.

I think they’re good.

Yeah, the 1.42v reading is just hot off the charger, and will substantially go down to its resting voltage in just a few hours, then stay there.
