Which rechargeable battery is better in shelf life in 2-3 ye

If a battery is on a shelf and you do nothing with it, its voltage will drop gradually, which is called shelf life of that particular battery.

I have recorded daily voltage drop of different rechargeable batteries for more than 10 years. I only put the first two to three year's data on the graph, since the software i'm using will not handle that amount of data.

The batteries which voltages were recorded daily are:

1. Rayovac rechargeable, AAA, NiMH. 1.2 V

2. Energizer AAA, NiMH, 1.2 V, 850 mAh

3. Power Genix rechargeable, NiZn, 1.6 V, 2500 mAh (average of 4 cells)

4. Duracell rechargeable, AA, NiMH, 1.2 V, 2850 mAh (average of 4 cells)

5. Raynovac Hyvrid AA, NiMH, 1.2 V, 2100 mAh (average of 4 cells)

6. 浩霸 haoba, rechageable, NiMH, 9 V, 280 mAh (voltages are devided by 7)

7. Raynovac rechageable, NiMH, 9 V (voltages are devided by 7)

8. Eneloop rechageable, AA, NiMH, 1.2 V, 1900 mAh

9. Digital rechageable, NiMH, 1.25 V, 1800 mAh (average of 4 cells)

10. Rayovac rechargeable, AA, NiMH. 1.2 V, 2000 mAh

11. rechargeabe 9 V,  lithium-ion battery. Missing in the picture, it was not mine, I don't own this battery

12. Tenengy rechargeable NiMH, 4/5A, 2000 mAh

Partial raw data recorded on the sheets:
