User Reviews about Toshiba PA3399U-2BRS Primary 6 Cell Li-Ion Battery

I'm so glad that I received this. My over-three-year-old laptop battery would only run for about 5-10 minutes unplugged. The new battery lasts for over three hours unplugged (a convenience that I won't take for granted) and arrived in good condition. A good purchase overall. I'm not sure where I could find a better price... -- Good purchase

Quick an easy was how it was to order and receive the item I ordered. Awesome customer service.. THanks -- Quick & Easy

I bought this battery replacement for my boyfriend's 5 year old toshiba satallite laptop. Before, he was getting about 40 minutes use out of his old battery due to its old age. It has been a month since he's received this and with this new battery he has been getting between 4-5 hours on one charge daily. So he loves this.

At the beginning, before my boyfriend used his laptop with the new battery in it, he fully charged it for a good part of the first day. Then, he fully drained the battery. Then he used the laptop like normal. He only did this at the very beginning because he believes this helps to maintain the battery life. There has been mixed reviews on the internet whether this step is necessary or not. But it certainly didn't hurt the battery since he gets great battery life now.

One last note, this battery is Toshiba branded as I made sure to get the real thing versus an unknown third party brand that may not be up to the same quality as Toshiba products. Therefore, I highly recommend this. -- Works like promised
