I have an old Acer Aspire v5-123 which has a 37wh battery with 15V, but it's so degraded that it only charges up to 18wh now, so I want to replace it.

I found an alternative online which has 4400mah and 11.1V which is the same model (AL12B32) and says it is compatible for this laptop, although I am worried about the voltage difference. I investigated a bit and some websites and forums said that replacing with lower voltage is bad for the motherboard and the battery. Is this true? Or will it be okay?

The old battery also has 4 cells, whereas the new one has 6 cells.

Note: I would charge the laptop with the charger I have now as the new battery doesn't come with one.

    The Aspire V5-123 oem battery is a 2520Mah type battery that is either manufactured by SANYO or SIMPLO, there are many battery retailers on the web that sell either genuine batteries lor copies, a 4400Mah battery is way over spec and its nearly twice the capacity of what the normal Acer fitted battery should be for this laptop, and it will be a FIRE HAZARD, so be very careful, as fitting none genuine and over spec batteries will damage your laptop, Only buy the below spec genuine or IF YOU REALLY HAVE TO a copy battery for your Aspire V5-123 laptop, that is my advice to you, good luck and hope this helps you out.

    Note: ZANDPARTS sell the Part Number: KT.00304.004 SANYO genuine Acer listed battery at USD $92.28 + Shipping (which includes their 25% Swedish VAT as that is where ZANDPARTS are located) for your laptop, which the listed Acer KT.00403.004 is a 3920Mah Poly Main Battery and NOT a 2520Mah battery like Acer lists in the Aspire V5-123 SG is, so this higher capacity Mah battery must work with your charger, so do it at your own risk.
