Why are Panasonic-9Cell so much cheaper than Sanyo????

[Volker1965]

Hi,

yesterday I wanted to buy a 9Cell-Battery for my T60. While cheking what FRU I'll have to take, I dicovered that there are two FRUs which fit my T60.

Batteries with the FRU 92P1131 (Sanyo) are about 186 Euro
and
Batteries with the FRU 92P1133 (Panasonic) are only about 82 Euro

Both Batteries have the same marketing-number: 40Y6797

Is there a difference in quality, lifetime or something?

I'm still wondering why they sell at such different prices.

Does anybody know something about the reasons?

thx
Volker
