Original 6 Zellen 4400mAh Akku Acer Aspire AS7552G AS7552G-5107
[DEKD-Acer-6Cell-Aspire-4551-423]

Good replacement for an Aspire-4551 battery,Purchased this to replace the original Acer Laptop battery which is now 5 Years old and no longer holds it’s charge. It fits without a problem, I don’t expect it will last anywhere near as long as the original, but time will tell. I will post an update should the battery not perform as expected. Hope this helps with your purchase.
