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.

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

This battery fits my old HP Pavilion laptop perfectly. I followed the directions for charging it properly and the battery came up to 100% with no problem. I find that it loses small amounts of power even though the laptop is always plugged in. Using a technique that I found online, I unplug from the outlet, remove the battery, wait a about 10-15 seconds, replace the battery, and finally plug the cord back into the outlet. The battery will then come back up to 100%. However, I do not think this is a fault of the battery but rather Windows 10 since I have seen this complaint on various internet posts. My laptop is 8 years old, and I keep it as a spare because it still works fine. I would recommend buying this replacement battery if it fits your laptop. I have not had it long enough to comment on longevity.

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.

It fits perfectly, installs easily, and instantly gives my laptop new life. I now get several hours of use on a full charge, which is a huge improvement compared to my old battery. It charges quickly, doesn’t overheat, and keeps my laptop running smoothly throughout the day. If you’re looking for an affordable and reliable way to extend your laptop’s life, I definitely recommend this battery!v

Perfect fit works like new again. A great price for new battery.

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.

This was the correct replacement battery for my laptop. It charged right up and works well so far.
