I bought this battery for my laptop and it works awesome. Just popped right in and now I've got a full battery. Once again I made the perfect purchase but as soon as possible

Correct fit. Battery did run down pretty fast though.

Great fit. Good price too.

I installed the battery into the laptop and charged it. The battery was recognized and charged in a few hours. It works great.

This is my second Futurebatt replacement battery for the HP 593550-001. I exchanged the first one because it would no longer power my laptop despite showing as fully charged. Prior to exchanging it, the battery initially powered my laptop running Ubuntu Server 24.04 for two hours and 19 minutes (100% charge down to 18% charge). The energy at full for the battery was 48.6624Wh during and after that first use. The second time I used the battery I was doing more with the laptop, and it went from 100% to 2% charge (triggering the automatic shutdown) in one hour and 50 minutes. When I restarted the laptop on AC power, the energy at full now showed 46.176Wh (a drop of about 2.5Wh), and the battery fully charged up to 100%, but would no longer power the laptop. I made several attempts to get the battery to power the laptop, but nothing worked, leading to the exchange. The second battery arrived at 56% charge (27.7056Wh) and showed the energy at full charge as 48.6624Wh, the same starting point as the first one. The first time I used the battery it went from 100% charge to 38% after 90 minutes. The next time I ran the laptop off battery power it once again went from 100% to 38% in 90 minutes, then dropped 7% for each of the next two 10 minute blocks until it was at 24% after 112 minutes of use. From there it dropped down to 2% within the next 9.5 minutes and triggered the automatic shutdown. Once I powered on the laptop and recharged the battery the energy at full charge had dropped to 45.8208Wh. It had lost 2.8Wh of battery charge off its maximum. As a result, on its next use the battery went from 100% to 34% after 90 minutes. By this time I realized letting these batteries drop too low clearly impacts their long-term capability, so I altered the power settings on the Ubuntu operating system to consider the power critical once it gets down to 20%, and to automatically shut down when the battery reaches 15%. The first time using the battery after making this change it went from 94% charged to 18% in one hour and 48 minutes. I plugged in the laptop to start the recharge process and the battery wouldn't take a charge. After several hours being plugged in without charging it had dropped from 18% to 17%. I tried unplugging and plugging in the laptop multiple times, along with restarting it, with no success. What finally worked to get it to take a charge again was removing and replacing the battery while the laptop was powered on and connected to AC power. I fully charged the battery (up to its new maximum of 45.8208Wh) and once again unplugged it. I ended up getting distracted and the laptop drained the battery to 15% then automatically shut down. After plugging the laptop back in, the battery recharged to 45.8208Wh, and that continues to show as its energy at full level. I share all of this to say that these batteries work, but with some caveats. They provide a good amount of power, but you have to be extra careful with them and recognize they are quirky and the quality control is not top notch. The fact the original battery very quickly refused to provide a charge, and the second one at one point refused to accept a charge, does not speak highly to the build quality. If you go with one of these, I would recommend updating your power settings to avoid letting them drop below 15-20%. I am using this laptop as a server on an internal network, so the laptop is not getting put through any sort of significantly heavy workload. Under greater strain I would expect the battery to get drained more quickly, requiring extra diligence to ensure it is not drained too low and causing a reduction in its maximum power.
