t40 battery need advice

[rook]

hello,

my oryginal battery dies, has 214 cycles and 10Wh capacity left, so i'm looking for new one.
does, anyone hear about battery for thinkpad T40/R50 battery based on Samsung cells ?
i've found 5200mAh battery under $100, and seller is telling me that this battery has above cells.
how do you think it's worth ?

Also OEM is the best for replacement. If you check "Batter Information" with Maximiser you can see the Manufacturer.
