My battery will not charge to 100%
I have had this unit for about 6 months. I use it on battery almost daily. Just in the last few days the battery stopped charging all the way. The battery only charges to about 50%. I have the 9 cell long life battery. I understand that batteries get old but at just 6 months this happened all at once.
any insite on how to get back to a full charge would be appreciated

li-Ion batteries have a bad habit: whenever fully depleted, they lose a few cells, to the extent that they might not be able to hold a full charge if enough cells are damaged. In other words, repeatedly using a laptop (or any other Li-Ion powered device) to battery depletion can shorten the battery's life significantly. You might want to keep the batteries fully charged whenever possible and avoid fully depleting them too often.
There is also the habit of "re-setting" the batteries by using the "fully deplete-fully charge" procedure. It only applies to niMH or NiCD batteries ( and is used to erase the "memory effect") but is damaging to Li-Ion batteries for the reason mentioned above. Unfortunately, not a lot of people know that and they start doing this tho their cellphone's batteries and to other devices that use li-Ion.

You probably got a lemon, a remanufactured one, or simply a knock-of.
Your best bet is to RMA it.

Not being able to charge at all is a known issue with some acer products. The fix is to update the bios. You can find the bios files and how to update on the acer web site.

Acer knows that their Aspire Laptops have battery failures and they still sell them without fixing the problem. The only resolution is to spend your own money shipping the Laptop back to them and wait two weeks to get it back. They know there are problems and they elected to keep shipping faulty product because it's cheaper than fixing it. Acer believes it's cheaper because most people don't understand PC's. DO NOT BUY ACER LAPTOPS!!!
