Problems after 1 year of no usage

Lithium batteries do have a life span determined by how many times the battery is discharged and recharged and how hard it is worked on the tool. Batteries get hot while charging and discharging and heat is what ages batteries. Lithium batteries, depending on usage, will last from one to three years. I've seen some last five years but that's rare. They also have numerous cells and a circuit board that can go bad and kill the battery. Chargers are designed to check the battery's condition and won't charge a battery if it detects something wrong. If your battery is under one year old, it's covered by the warranty. If it's over, you'll have to buy a new battery.

You can do any of the following:1. Buy a new battery from a Nokia Care Center2. Drain Battery completely then recharge fully3. Use some battery saving application from the Ovi Store4. Reduce your Multimedia usage, internet browsing, game playing etc

These batteries never last very long. That model of drill is no longer made but I did find some refurbished batteries on EBAY. However, with EBAY you get what you get. Personally, I would never buy a refurbished battery and besides, they are way overpriced for a refurb. Sorry my friend but you would be better off just buying a name brand drill with Ni-cAD batteries (18V or 24V are the most common). I have a 24V DeWalt that I love and replacement batteries are cheap.

Go to teh phone settings, and under sync accounts disable all teh sync accounts that you are not using such as stocks etc. These constantly use up data and hence drains your battery as they do so in teh background. This should greatly improve your battery. If not, your battery must eb damaged and i woudl suggest you purchase an extended battery which may have up to 40% more battery life.

Yes its normal. To maintain the most power adjust your brightness bar down to 1/4 or 1/2. Keep the push mail function off when you don't need it. Don't recharge the battery until the unit shuts itself off. Then recharge the battery to max before using. This is called conditioning the battery, even though many say you don't need to on lithum ion batteries because there is no memory effect. But their full of sh.t, cause you do the first time you get the battery and should do it once a month to extend the life of the battery.

I use the adapter plugged in all day long, it will not do any damage to your battery. You can leave it plugged in a work as long as you want. Just make sure you get the lithium ion battery as that is the latest..in fact I would get it off of the Acer home page if possible. As for as how long a battery last, depends on the usage and how many times you recharge it. Lithium are good for over 1000 recharges so again depends on your usage. Its the recharge that wears it down. Hope this helps. Pls rate this solution.

i suggest replacing a fresh battery will most likely solve your prob, overtime rechargeable battery can drain easily, try changing with a new battery and see if it does work well, there might be insufficient current, thats why it tends to drop of voltage easily upon using, 
there is a specified lifetime for rechargeable battery, depends on your usage and charging method, theymaybe fully charged but sometimes wont give you enough power to drive 
cheers

I've been having problems with the batteries and the camera refusing to start even with fresh batteries. I bought loads of new rechargable batteries and have finally found some that work. Duracell rechargables. Theyr'e brilliant and keep their charge for ages despite continuous use of the camera! Last summer I managed to take 975 photos before the batteries finally decided to give up!

Nothing is wrong with the camera or the batteries. Rechargeable batteries of all kinds will self-discharge over time. Charge them fully (if they are NiMH completely charge and discharge them a few times), and you should see full battery capacity.
