Customer ratings and reviews for HP MU09 Long Life Notebook Battery

Rated 4 out of 5 by It's a good product I think there isn't a lot you can say about a new battery. The "shipping" was perfect, the product fits perfectly in my laptop and it last for longer than my 6 cells battery because this one has more capacity (9 cells). August 21, 2013
Rated 2 out of 5 by No Good this MU09 long life battery-lousy- ONE [1] day, after full chg. & its COMPLETLY drained!! My original battery NEVER did this....would expect more from a $ 140+ battery!! VERY unhappy--sorry i bought it.... rec'd it fast--which was nice... June 21, 2013
Rated 5 out of 5 by much better! My old battery not only had minimal life in it but the system was starting to shut down with no notice whatsoever. This new battery, while only a week or two old, is up to 4 hours of runtime. Free at last, free at last! June 14, 2013
Rated 4 out of 5 by Great life and prop features My last battery died while I was abroad, so you can imagine what a life-saver this new one is for me. It lasts about 4-5 hours (more when I don't use video) and I love that the battery props up my computer. I had a little trouble with making the battery fit but for the most part, the battery is perfect for my Pavilion dv6. June 10, 2013
Rated 5 out of 5 by good Great customer service!! Great battery! May 24, 2013
Rated 4 out of 5 by This product is great. This battery last longer than the original battery that came with my G6 computer. I am very pleased. May 20, 2013
