Perfect ENVY 13 battery replacement
Fit into an Envy 13 perfectly. It is more rigid than the original but seems to work fine. Easy to install and only about 1/2 hour of time.

Holds a charge
No instructions but was easy to install. So far so good. Holding a charge and slow to drain. I ordered a second one for another laptop and very satisfied with both.

Good Fit. Ok Battery life
The battery was shipped in a bubble mailer inside a larger box. The picture shows it would have been shipped inside a smaller box too. I prefer this as the battery and small retaining tabs will be more protective. However at this price point I understand why it was shipped this way. I only ask that the pictures shown offer an accurate representation of what will be received. The battery fit good and the overall color was accurate. Battery life is ok ranging from 1:30-2:00 hours depending on what you're doing. Time will tell for longevity. Would definitely recommend and buy again.

Not working right only 2 months since purchasing
I was originally very happy with this battery that I purchased on April 22, 2025. Now only 2 months later the battery is not working right. I have done all the battery testing and calibration that I can find to do on my laptop to no avail. There were a couple days where the battery charged back up to 100% and seemed like it was working again, but that only lasted a few days and now the highest it will go is 26% and that's with keeping it plugged in while using it. Sometimes it won't even charge that high, or charge at all. If I unplug from power, the battery will quickly go to 7% and shuts down my laptop. It never seems to reach 0%, but hangs at 7-9% most of the time. This is UNACCEPTABLE!! The purpose of the battery is so I can use my laptop while not having to be plugged in. What is the warranty on this battery? I'm for sure not looking forward to replacing the battery again so soon. It is kind of stressful going through the steps to replace it. Does this company send batteries that die this soon on purpose? I wish we could chat back and forth with others on here to find out if this is a common occurrence. Maybe the vendor will contact me after seeing this review??

This battery seems legit after several days of usage!
I'm impressed so far! My battery arrived ~70% charged. I drained it down to 5%, charged it up to 100%, and repeated this process two more times. I've been using it for a few days, disconnected from power supply and it seems to hold a pretty good charge. I'm able to go 4-8 hours of continued usage before I need to charge back up. Thus far, this is a 5 star battery replacement in my book. I'll plan to update this review if battery quality goes south in the next year or so.
