I have the standard Acer Aspire one 532h-2Db, I am looking to upgrade the battery from a standard 6-cell to a 12-cell ( for more longer terms away from the mains ) and I've hit a problem, I cannot seem to find ANY battery with the same voltage / more cells for my model.

This is the battery that I thought was compatible as it says 532h but I discovered its 0.3v over the standard and was worried it would cause damage.

Could someone help me and tell me if this will damage the laptop? Also if it is possible for a higher cell battery for this laptop?

This is the original battery

It becomes spam if you keep reposting. Don't do it. –  random Sep 10 '10 at 19:12
    
Ah I didnt realise :/ , thankyou does anyone know what's the answer? –  Ben Sep 10 '10 at 19:26
    
Let's leave the question for a few mins and we will see! :) –  JNK Sep 10 '10 at 19:28
    
will do :) sorry, I haven't had much experience here + got very worried with my choice of laptop as you can imagine :) –  Ben Sep 10 '10 at 19:32
    
.3v will make no difference, if it fits it will work. You can ask the seller a question on eBAy to confirm the compatibility with your system. The quality of the cells inside the battery is another question. –  Moab Sep 12 '10 at 21:28

Can you use an external Universal battery similar to this? Universal Battery

I used one from APC for several years while flying. Worked great and fit the briefcase easily.

It COULD be a possibility but does this hold more charge? I origionaly thought of using a literal car battery with a ac to dc converter? –  Ben Sep 10 '10 at 20:47
    
Car battery and inverter would naturally work. The APC one I had ran my P-3 Toshiba for 4.5 hours. Origianl battery was lucky to get 2.5 –  Dave M Sep 13 '10 at 12:25

With batteries/adapters current rules apply as in all cases.

The concern is not so much voltage as it is amperage. (it needs to be close though)

The biggest problems is if you have a too LOW amperage level, if this is the case the device will attempt to pull more current. This will act like holding a finger over a hose. you will actually cause damage if it is too low!

This is, of course, only true if the current is available to pull and I should mention that it is possible for over voltage to cause damage to sensitive devices, I'm am just speaking in a general sense.

so are you saying that in this case it wouldnt work ? The Voltage for the 12 cell is 11.1volts + 10400mAh The voltage for the current battery is 10.8 volts + 4400mAh so shouldent I worry + I mean will it damage it ? –  Ben Sep 10 '10 at 20:45
    
are you referring to not how many amps it holds but how much it applies? –  Ben Sep 10 '10 at 20:49
    
bump? - need real help –  Ben Sep 11 '10 at 14:00
    
Heh, I'm not going to say either way since this relates to a potential hardware damage. But I will say in the past I've used over amperage levels fine and voltages further then the difference that you have. –  Jeff F. Sep 13 '10 at 16:21

Battery voltage is a function of the cell voltage and the number of cells. Most types of laptop cells produce around 1.2 volts per cell, so, eg, a 12V battery would have 10 cells. A 12 cell battery would have twice the voltage of the 6 cell version with the same cells.

Battery capacity is expressed in ampere-hours, and is a function of the cells used. If you want more battery capacity you need to use (larger) cells with a higher ampere-hour rating.
