--- Quote ---Anyway, following up on the cheap Aldi cells, after 2 cycles with my charger, they took almost 6000Mah (they are 4000Mah cells) and restituted around 4500Mah with a 0.9A discharge Not bad at all for a 10 euros pack!

Fred,…..look, I know I’m a bit thick & slow on the uptake, :oops: and on top of all that I’m only an Englishman……………but what are you talking about??? :?:
As it reads it seems you’re saying that your 4000mA/h cells took 6000mA/h to charge, and discharged a total of 4500mA/h! How does that work??? :!:

Fred:
Hey Keith,
As far as I understand, if you charge a cell, really slowly, or carefully, you can pack up more energy in the cell, giving you back a bit of that extra energy.
I've heard that a long time ago, when I use to have buddies who worked for Saft (great time, use to have all the latest batteries for free at the time :D ).
I think this is commonly(?) used by the F5 guys.
Anyway, almost 2000Mah more stored, is quiet a lot I think, but that's the numbers the charger give to me :D
No expert in that field at all, but in my experience, not a surprise :?:
Happy Days:
Well,……I’ve never heard of that before. :)
……..There’s an old saying, “You learn something new every day.” :D

Hi fred
When it comes to batteries, if I am not happy with it, I throw it out!, cheaper than replacing a model. The b52 has 2 x 6v 3300 packs, after the test flight I found that one pack had discharged down very low, only it had the back up pack, I could have had a few bags of foam to pick up. I checked this pack, and found a bad cell. The cell showed green on the checker.
Fred:
Hey John,
Same here, that's why I cycle them etc and check the readings.
In this case, the pack is performing great, the issue come from the charger :!:
Lucky that they were holding the charge pretty well, as I was only charging them to 20% of their capacity in fact :shock:
