5 Star Review Feb-14-2014
"Excellent Service! I ordered a new battery and charger at a good price at 10:42am on Wed, got an order confirmation from you at 10:46am, a shipping confirmation and UPS tracking number at 1:42pm and the right product delivered at 9:53am the next day (23 hours later). It couldn't have been easier or faster. Good work. This is exactly how Internet business is supposed to work. My thanks to the team."

5 Star Review Feb-13-2014
"Good morning: The new battery arrived and following the install directions, my laptop registered it to be almost 80% charged. It took the rest of the day to run it down completely, so I'd estimate 7 hrs of use at 80%. I was somewhat cautious ordering this battery as I'd just gone through a headache return project on a battery purchased elsewhere. I'm 100% satisfied with this battery and have already referred a couple of my buddies to your site. Thank you"

5 Star Review Nov-03-2013
"I recently called about replacing a Laptop Battery One battery that would no longer hold a charge. I bought it about a year ago and was amazed how courteous a efficient your company handled everything. No hassle, no problem, just sent it back for a replacement!
I very seldom take the time to email a company about their service, but you are the exception. Can't tell you how pleased I am and I will certainly recommend you to others as well as continue to do business with you. The replacement battery is working fine and holding 100% charge."
-Barry Nelson
4 Star Review Sep-19-2013
"The battery was shipped quickly and without fuss and, so far, seems to be exactly what was promised. Unfortunately, laptop batteries often take weeks or months to show substantial defects, so it's not yet possible to know whether this item will continue to do its job. Assuming that it does, then my experience will have been a satisfactory one."

"This company's website is easy to navigate and the speed of receiving my order was unbelievably fast. The battery fit perfect and has been charged and discharged 6 times per Laptop Battery One's directions. Looks like the battery is holding about a 5 hour charge and my daughter is ecstatic as I also am. Great company with quality grade A cells used. I would recommend this battery company to anyone."

Review Jul-14-2013
"Awesome. I watched laptop battery one's instructional videos, reviewed the competitors information, did my own search and ended up coming to Laptop battery one because they gave such good information at what seemed like a fair price. I highly appreciated all the educational and transparent information that was provided. I also was able to search the web and find a discount coupon which covered, basically, the price of the shipping! Then I received my battery in just two days even though I chose the 7-10 day shipping. Lastly, I highly appreciated the step-by-step instructions on how to set up and use my battery properly. I also felt really get about getting the battery because of the 60 day money back guarantee. Overall, this was one of my BEST shopping experiences ever. If only everyone could sell products like Laptop battery one does, consumers would be much happier."

Review Jul-13-2013
"My experience with Laptop Battery One was GREAT. I was taken care of in a VERY EFFECIENT and TIMELY MANNER. This company guided me through every step of the way and followed up with E mails to make sure I was notified of what was going on throughout the process. I am now enjoying my product and feel so secure that I will use Laptop Battery One AGAIN if the need arises. The PRICES are UNBELIEVABLY CHEAP with the full backing of the company. Thank You Once Again. I have already recommended you to all my friends."
