No, you should NOT use a battery with different voltage. It may not fry your computer, but it will certainly not work/charge properly.
But it seems impossible, that two batteries of the same symbol have different voltages - one is 3-cell type (3x3.7V lithium cells) and the other is 4-cell (4x3.37V). This usually means, that the second battery will be physically larger (4 groups of cells instead of 3).

If your original battery reads 11.1V, then it's most probably the correct voltage - perhaps there's a typo on the website? Try to consult them so they double-check the specs of this battery.

In fact, some laptops of ACER and DEll have a special design for supporting two voltages. Without doubt, your laptop is just the one which can bear two voltages. So, please don't worry about, you can use the 11.1v or 14.8 battery based on your convenience. battery-adapter.com sells both batteries, you can find their description through this link:

Where can we buy a battery of acer laptop aspire 4736/4736z/4336 series?How to take care of the battery of the laptop especially acer brand?


You should get it at your local computer store.

The replacement doesn't have to be an Acer. I have seen after market replacements, that work better than the original battery.

When you buy a new battery, you should consider looking at the number of mAh. It is written on the battery. This number indicates the time before complete discharge.

I have seen original Acer batteries that were 2200mAh, while replacements were 4400mAh.
So if the 2200mAh gives you 3 hours of working time before recharging, the 4400 could give you twice as much, so nearly 6 hours.

I have used the new Forza brand replacement batteries on a Acer Aspire One, and I am very glad with the results. I am not sure if they have the model you are looking for. if they have it, you should get one.

Hopefully this helps you

I want to overclock my acer aspire 5050 this the review: * Processor: AMD Turion64 x2 TL-50 (1.6 GHz, 512 KB L2 cache total, 256 KB on each core) * RAM: 1 GB 533 MHz DDR2 RAM (2 x 512 MB) * Hard...


I have the same system too. None of the tuners such as RIVA work well w/ integrated notebook card, and u r graphics card is pretty ghetto. I could however, download POWERSTRIP and tune up a minescule 300-400 MHz but it won't let me access memory clock. More than this I could do no further overclocking.

My battery dies within 20 minutes of use. I've let my battery charge overnight but i still only get about 20 to 30 min of life out of it. is that standard for an Acer Aspire 3000?


If the battery is more than one year old, or has been often used with the power supply plugged in, it might have degraded.

Sometimes you can regenerate it to some lesser extent by completely draining it and recharging overnight (but that's apparently what you already did).

So I'm afraid you will have to replace it.

A new Acer battery (4400 mAh) should get you at least three hours life, and up to six hours by being real careful (lowest screen luminosity, no disk activity, no heavy usage: e.g., vanilla word processing)

New 6600 mAh battery won't charge


Is the AC adapter the original that came with the laptop or is it a replacement?
Check the label on the laptop (on the bottom of the laptop) for the voltage and current requirements.
Check voltage output of the adapter with a multimeter, this voltage should be slightly higher that the voltage than what is shown on the adapter's label because there is no load on the adapter.
It could be that the current (amps) that the adapter is delivering less power than the laptop's requirements, whilst it can power the laptop it may not be sufficient to charge the battery fully.
Try charging the battery overnight by shutting down the laptop but leaving it connected to the mains. Then boot up the laptop in the morning and check the battery's charge state. If the battery is at or near full capacity, then the problem is a (part) faulty adapter.
