Battery for Acer Aspire 5920G

Hi guys,

My original battery is almost dead, and I'm looking for replacement battery. I noticed that there are two kinds of batteries for the 5920g, one 11.1v and the other one 14.8v. My original battery is AS07B32 14.8v 4,800mAh. Should I look only for 14.8v battery or the 11.1v will fit ok too ?

Thanks

 

Isn't the other battery- the 11.1v one- 4000mAh?

 

Nope, they all 4,400, 4,800 or 5,200mAh

 

you can any of these and it will all work just fine...
but remember 14.8V + 5200MAh cells give you about 75Wh which is very high and gives you a quite good run on battery...

 

As long as the voltage is the same, get the one with the highest number mAh

 

it can run on both types of battery, i have tried it on my own but do what Arminator says

 

It's hard to find more than 4,[email protected] on ebay. Do someone know this website - Cheap laptop batteries ?

Can you recommend a place to buy that ships worldwide ?

Thanks

 

Why you wouldn`t take a 14,8V with 5200mAh cells, the same one I am using?
My works like a charm and I have no regrets... It gives me over 2 hours of normal use (surfing, word processing etc) even with my power hungry old Turion X2...
In other words on your Intel platform it should give you much much more if compared to your stock 4400mAh battery...
To compare check this: 14,8*4400=65120mWh vs 14,8*5200=76960 mWh... The later has almost 20% more capacity which in real time usage would mean this: if your 4400mAh battery lasts 2 and half hours (I am talking about a new and fresh battery), then the one with 5200mAh cells would last around 3 hours, with the increase of about a half an hour what IMHO is more than a very strong argument why to get a battery with higher capacity cells...

Hope this was useful...

Cheers

 

I'm using the original Acer 4,800mAh which is 14.8*4,800=71,040mWh and it lasts 3:45~ hours.

I found a 5,200mAh 14.8v battery on ebay, but from my experience I'm not sure if the Chinese replacement will last more than the original...

Anyway I think I'll just buy it.

Thanks!

 

I am glad we gave you useful advices...

Cheers

 

Couldn't find a definite answer for my question so I will post it here.

I still own my 4 years old Acer 5920G (301G16) and it's going pretty strong still. About to purchase an SSD to make it perform better.

The battery inside is AS07B31 11.1v 4000mAh. Even after 4 years and some months, I get like 30 minutes of battery life out of it.

My question is, will a 14.8v battery work on my laptop? I will be buying a compatible one from eBay. I found a:
14.8v 5200mAh 8 cell
http://www.ebay.com/itm/140619548720?ssPageName=STRK:MESINDXX:IT&_trksid=p3984.m1436.l2649#ht_2074wt_984
and a 11.1v 5200mAh 6 cell
http://www.ebay.com/itm/270750492419?ssPageName=STRK:MESINDXX:IT&_trksid=p3984.m1436.l2649#ht_3895wt_1185
batteries compatible for my laptop. I guess the 14.8 with 8 cells would give me more battery life, but I have found mixed results whether it would work. I also read the service manual for the 5920G, but it doesn't state anything about voltage for the battery. They are both 5200mAh, but the 14.8v is 8 cells. I don't know if that means better battery life.

What would you do in my place? Purchase the 14.8v or the 11.1v and would the former work?

Thanks to anyone for replying.

 

14.8V * 5200mAh = 76960 mWh
11.1V * 5200mAh = 57720 mWh

So, get the 14.8V one, it will last 33% longer than the 11.1V one.

 

Thanks for replying NetRoller 3D! I am fully aware that the 14.8v battery will give more juice, my concern is whether it would actually work. If it would work however, can the 14.8v battery be harmful for my PC and fry something inside.

 

No it won't be harmful. Input voltage into your machine is not the one used by components.

 

The only component that directly connects to the battery/AC is the MXM card, which is designed to accept anything from 7 to 22 volts (values from MXM spec).

 

Thank you guys for the replies. I'll believe your judgement and purchase a 14.8v battery.
Cheers!

 

Hi,

Did the 14.8V work?

I'm afraid that the 14.8V battery can cause harm to my 5920 which untill now has an 11.1V model.

I'm also confused because the AC adapter output is 19V DC.

At least one of the replies you've got seems to say that the computer is able to convert both 11.1V and 14.8V to the voltage that it internally needs.

I just want to confirm with you before I go and order an 14.8V. The original battery was made in Japan and the replacement battery I'm running now is Made in China and the performance has been very poor since day 1, compared to the original one.

Thanks
