In this charger no cell from 3.9v will be charged.
A thousand cells when they are at 100% mark 4.195v or 2 figures 4.19 and after a week they are still at 4.19v or 14.185v I am going to measure one now that it has been a week and a few momentary lights.
Proof:
1 week and a few ignitions due to a power outage and looking for things at home, it reads 4.17v, I charged it with a charger that carries the flashlight, I left it at 100% at 4.19v, if I had not used it, it would read 4.19 or 4.185v or so I think.
Now the battery of the S2+ charged last week and used on Sunday in a rally at night (I am a co-driver but I was a spectator that day) to go to the car and play with the children, turbo mode is at 4.14v (not continuous use )
These two batteries do not charge in the Opus that has come to me, because it exceeds 4v.
As you can see in random use and for a week it has withstood the tension very well now they stay that way until the next outing but the Opus won’t let me charge them.
I will charge it as I always do and they will stay at 4.19v
If it went down to 3.8, I could charge them in the Opus and I would leave them at 4.16v, which is the same voltage, using them for a week, this is not worth it, so this charge is useless if I have to take them out and put them in another charger.
100% of this charger leaves them at a very low voltage, the equivalent of several uses and a good week to be exact, about 5 days one and the other I don’t remember.
The one in the photo has been stored for about 4 months without charging and it was at 4.16v but it is recycled, it was charged with a diy charger at 4.19v or 4.20v, I don’t remember which one I used.
I have an RC charger when I was flying helicopters and I calibrated them to three figures 3.xxx both the voltage and the charge and discharge (complicated because these chargers are not exact, I kept 2 figures well 3.xx) but it is a mess of cables every time I have to load them.
I’ll see what happens but I don’t think I’ll want a replacement one, I’ll use mine, I’m more confident, I know it will charge the right A’s because I calibrated it myself and I can cut whenever I want due to temperature, time, voltage and load.
The bad thing about this seller who never answers before or after and maybe it’s false, it’s already stored and I have it packed, I wouldn’t use it or give it away, I should have measured the charge intensity to see if it’s real.
Thank you!
