NP9150/P150EM Replacement Battery and mSATA question

I have two questions in regards to my Sager NP9150 (Clevo P150EM). One is I just bought an EVO 840 250GB mSATA drive since it was only $100 on amazon. If I recall correctly, the mSATA slot on this model runs at SATA II speeds not SATA III correct?

Secondly, I've been running with a near useless battery for years now. I typically burn through a battery fairly quickly. Maybe within a year and a half before I'm already down to 70% wear. Where can I buy a brand new battery and/or AC Adapter (it is starting to fray on some of the shielding)? I looked on Sager's website about 6 months ago and they had them for sale but I decided to hold off till I started using my laptop on the go more, which I have been now recently. Unfortunately I just checked their website and they don't seem to offer them any longer for my model. Anyone know of a reliable retailer where I can purchase replacements from? Also in regards to the wear of a battery, any tips for reducing how quickly a battery wears out for someone that uses their computer about 80-90% of the time?

 

Yes it runs at SATA II.

The SM series battery should fit IIRC, but contact your reseller and they should be able to help you.
