Replacement Battery for HP MU06 MU09 Laptop Battery, HP Spare 593553-001 593554-001, Compaq Presario CQ32 CQ42 CQ43 435 436, Pavilion DM4 G4 G6 G7 DV3-4000 DV5-2000 DV6-3000 DV7-6000

The battery is a pleasant surprise compared to other replacement laptop batteries I have purchased in the past. This one installed quickly, fit perfectly in my old laptop and worked immediately. Although it's not as big as the original 9-cell battery, this one is lasting several hours after a full charge. The fit and finish are excellent as there are no gaps around the edges where the battery meets the laptop shell, nor any wiggle or play when locked into place. I highly recommend this seller as I will be coming back for more replacement batteries soon.

As Described the Battery Pack work perfect with my Old Laptop HP Pavilion G6 and have No issues replacing the old battery with. So great that even had power store for me to boot the laptop right from the package and without first charging it. I am very please with the battery quality, the price, the feel of it and how it fit perfect. The installation was super easy, just removing the old one and alining the new one into place.

Battery seems to have taken a charge. I never use the laptop on battery power for long. But I like to get it started while I am setting up the work station. These are inexpensive and do the job. I had an employee leave the computer on when they put it away for an extended time and killed the old one. This is a good replacement.

Reliable but Not Top-Tier Battery Replacement This replacement battery does the job—it charges well, holds power decently, and brought an older HP Pavilion back to life. Out of the box it installed easily, clicked into place without issue, and was recognized right away by the laptop. After a few full charge cycles, I found the run-time landed at about 2–3 hours depending on workload, which is acceptable for basic browsing, document work, and video streaming. The construction feels solid, and it doesn’t wobble or shift once seated. Heat generation is minimal compared to some off-brand batteries I’ve tried, which is a plus. That said, it’s not quite the same as the original OEM battery in terms of longevity—if you’re running heavy tasks or expecting a full workday unplugged, you’ll likely be disappointed. One thing to keep in mind is that these aftermarket batteries sometimes vary slightly in actual capacity despite the advertised numbers. In my case, it performed consistently but never quite matched the original battery’s endurance when new. Bottom line: A good, budget-friendly replacement to get an older laptop functioning again, but don’t expect OEM-level performance. Great as a backup or for light to moderate daily use.

My HP Laptop is sooooo old. But I’m so glad this design still exists. The battery quality is great! Fits my laptop perfectly. Easy removal and was easy to install. I’ll use this company again

is as advertised

Purchased this battery in late 2020 because the original (after about 6 years) was only keeping my laptop on for about 30 minutes unplugged. The replacement held power longer, not as long as the original when new (maybe about 2 hours? or less) when unplugged, an improvement but not great. This is all with normal to light use. Power retention has been progressively diminishing, to the point I hadn't been able to work unplugged for more than 20 minutes at a time for the better part of a year. In any case, by now the battery is effectively dead. Even while plugged, charge only reads 85%. When unplugged, the laptop just dies. No sleep mode, no powering off, just dead as if there were no battery in it at all. You get what you pay for and only a temporary fix.

It fit my computer. I let it charge up overnight before using and it seems to be working well. I did check the battery number and made sure it was a match for the computer before ordering.
