The packaging & the presentation give you a sense that this item is different.
Open the box and just look,please be as good as you look,so far it is.Perfect fit for my Acer, recognized instantly & powered up.It is still in the "running in" period but I am very happy.
This is the most I have spent on a replacement battery,I think I have been buying too cheaply.

I've waited 2 months to test this product before writing a review.

When the product arrived I was pleasantly surprised at the high quality packaging; everything was wrapped and well protected with a friendly, customer focused leaflet introducing Green Cell, with clear instructions.

On first use the battery only seemed to charge to 70%, but after following instructions provided and leaving my laptop on charge for some time, the battery reached 100%. Since then the battery charges fully every time.

After 2 months almost daily use this battery works at least as good as the original battery that came with my Aspire. On full brightness it lasts about 75 - 90 minutes for a 17" screen, which I seem to remember is at least as much as the original battery. So far I've had no issues such as overheating or sudden drops in battery life.

For info, I charge to between 98-100% and discharge to roughly 5%. I have occasionally charged to 100% and forgotten to unplug, with no problems. I

Perfect fit for my old Acer Aspire 6390G laptop. Arrive with approximately 90% charge and calibrated just fine over a few fully charged/fully discharge cycles. I cannot review on the longevity of the battery pack but hopefully will last a few years if stored correctly and used correctly. Arrived from Poland in just under a week with a tracking number, of which, the package could be tracked from initial despatch to delivery. I would use Greencell Energy again if needed.

The battery was very carefully packaged, which was confidence boosting, and it came with very clear instructions to enable me to get the optimum performance out of the battery. I am very pleased with it and I get about the same usage time from the battery as I did from the origonal one that came with the computer when it was new. Good enough for me then!
