Hi. A couple of months ago I saw some AAA Ni-MH cells made by GS Yuasa. Since most of the sites you usually recommend to get eneloops or any kind of batteries are in the US and shipping costs make buying from them a bit expensive to me, I got a pack of four enitimes just to try them.
Since my C9000 was busy doing break-ins I used a couple of them in a remote, but I think the drain can be said negligible. The cells are advertised as 750 mAh
First I did a discharge test:
Cell -------- Rate (C/D) ------- mAh ------ V
1 ----------- 0/200 ---------- 624 ----- 1,18
2 ----------- 0/200 ---------- 628 ----- 1,18
3 ----------- 0/200 ---------- 629 ----- 1,14
4 ----------- 0/300 ---------- 616 ----- 1,17
Surprisingly the readings were more stable than expected. The only worry was the lower capacity under higher discharge rate. Then I did a Break-in (Since I couldnt use 750 to specify the capacity I used 700)
Cell -------- Rate (C/D) ------- mAh ------ V
1 ---------- 70/140 ---------- 786 ----- 1,43
2 ---------- 70/140 ---------- 789 ----- 1,43
3 ---------- 70/140 ---------- 794 ----- 1,44
4 ---------- 70/140 ---------- 790 ----- 1,43
Very stable values again and with higher capacities than advertised (as you know thats not common in cheapos).
Since I have some primaries in my AAA devices I dont need them right now and then I decided to let them rest and discharge one at 1 month, 6 month and a whole year to test the self discharge.
Does anyone has experienced with this brand before?
