My W540 is asking me to consider replacing the battery. The original battery is a 57++, 9 cells, 11.1V, 8.96Ah 100Wh, Li-ion00 battery.
Searched on ebay, cannot find an exactly the same one. The closest match one is this:
----- does this one is better than mine original because of its lower V?
----- do you have a reliable seller from ebay or amazon to recommend ?
From the Battery Maintenance window I found there is a Battery Health Mode feature somewhere. But where I can find it?
