I am very happy user of Lenovo T520. I have upgraded to Intel 520 SSD disk and ram to crucial 2x4GB DDR3 and laptop is performing very well !
When I bought my T520, I bought one replacement battery- 9 cell battery(laptop came with 6-cell).
I have used it about 10-30 times only and kept it always only 80% charged in cool place(actually at room temperature 22C approx). After one year of no-usage I wanted to start using this replacement battery again.
I am very disappointed and confused. I have inserted my 9-cell battery with only 20 charging cycles and it has very low capacity and runtime. Please help me? What happned with my nearly 3 years old, but never used battery???
My 6 cell battery(about 200 cycles) is like new and performing very well(3 hours runtime and 95% capacity)
Many thanks for any useful advise
