replacement batteries and voltage differences

Hello,

I didn't really see an answer to this question as the situation is apparently usually reversed.

I have an Acer Aspire 3680-2682 which I have just replaced the screen on thanks to this forum. Now I'm trying to find a replacement for the dead battery.

Acer offers a replacement model LC.BTP00.001 for this series but does not have any in stock and doesn't give voltage specs. The original battery says it's rated at 14.8v but the LC.BTP00.001, according to every site I have found, is 11.1v.

I've seen useful discussions about the safety and particulars of using a higher voltage replacement battery but nothing about using a lower voltage battery.

Considering the quality and scarcity of documentation I've been able to get from Acer.com and its support techs, I don't necessarily trust that it's the right model just because they have it in their accessories catalog. Besides this partiular member of the 3680 group seems to be a question mark as it is not listed specifically in any of the documents I've seen. It's like it doesn't exist and tech support says it has no specs on this model. So it could be an aberration.

Anyway, if someone knows the mysteries of replacing a 14.8v with an 11.1v, I'm all ears.

TIA

If both batteries are officially sanctioned by Acer (and not cheap third-party rip offs), then I wouldn't worry about the voltage difference. The power regulation on laptops is generally quite forgiving and it already isn't too uncommon to see different voltages on different capacities of battery for a given laptop.

 

Don't go buying batteries in which Acer doesn't support, even something as simple as a battery can damage your entire laptop..
