Good service09/27/2019 ByLeigh Tracy Walters I can't fairly rate the battery. The replacement battery I ordered didn't work on my Toshiba Satellite; probably an issue with the motherboard. Communication with NextDayPower.com was easy and professional. I was able to return the battery and get a refund in a few days. I would highly recommend this company, despite my disappointment with the functionality of the product ordered.
