If you own a thinkpad, i would highly recommend use the preinstalled software to limit charging to 60-70%. I have mine set to stop charging at 60% due to me using it for work and thus always plugged in. The battery stats still says its above the capacity which is nice.Big hurdle was that lenovo whitelists batteries only made by them. So this battery won't charge until you install patched version of BIOS in your laptop. If you do a search online you'll find it easily.
