I bought my Edge 420 two years ago and really love it. But after installing WIndows 8.1 battery life decreased for 2.5-3 hours from one battery charge. I don't wanna back to Windows 7, because I like new OS without any lag and problem. Not long ago I read about 9-cell battery and want to buy it. But where? Which store or place do you recommend for buying?
And I know, that batteries capacity may go down because of time (laptop sales have begun in 2011). Should I buy new 9-cell battery? Or just forget about it and continuing using my old 6-cell?
Thank you for replies!

Welcome to Lenovo Community Forums!
Capacity of a battery declines as the battery ages, with the number of charge cycles and time at high temperature. Under average usage patterns your battery maintains approximately 70% of its power capacity after the first year of operation.
If you feel that the battery backup is too low, try doing a battery firmware upgrade and BIOS update. Check the Lenovo support site for any battery firmware updates for your particular model.
Refer this knowledgebase which explains some tips to improve battery backup.
Still if you feel like getting a battery replacement, I would suggest you to contact Lenovo technical support. I'm sure they would be of great help.
Hope this helps!

But I can't find this service in my country.
How many cost new 9-cell Battery for my laptop?
Maybe, there are somewhere other place, where I can buy what I need? Some online-shops?
