I thought you always replace the battery pack not just the individual cells. Like a car's tires, I'd think you want everything "balanced." Or buy both shoes, don't just replace the one?
1 - if the laptop has a little value, buy a new battery pack may be too expensive
2 - to replace a pair of cells you spend only 10 euro
3 - even if you buy a new battery pack,, repairing the old, you have a spare or Emergency battery
