Review: Works well with my Flex-14API, be careful with connector - Works fine so far, and the tools included are a clever touch to make installation easier. The connector is quite snug, and you sure don't want to force anything, but you must get it plugged in all the way for it to work correctly. Be careful, be patient, be well.

### ⭐⭐⭐⭐ It works, but I've had better
*by M***N on October 8, 2023*

It does the job. It fits my Acer Aspire One. Like every aftermarket battery I've been through with this laptop it's a little bigger and makes the computer sit a little taller. Despite being a bigger battery than the original, it doesn't perform better. The original was rated at about four hours, but only ran for three. This usually lasts for about two. The original died after four years. This one lasted only one and a half years. Aftermarket batteries for this computer (I've been through a few) typically last about two years, for me, which makes the longevity on this one a little less than average but not my worst purchase. How do you know if your battery has reached the end of its life? I'm amazed at how many different ways my computer behaves when a battery goes bad. It's been a little different each time: -Computer produces a notification telling me it's bad -Computer repeatedly beeps as though it were being plugged and unplugged. -Battery indicator light flashes, orange. -Computer drops dead at what was supposedly 50% charge. Yeah, I've been through a few batteries for this computer. So, this one has performed near average for aftermarket batteries, which is not quite as good as the original battery, despite looking like it should be twice as good.
