I have an Acer Aspire V3-771 laptop (which is three and a half years old) with its original battery. As the battery is not holding the charge for as long as it used to I decided to replace it. I inserted he new battery, which already showed a charge of 60%, and let it run down to the point when the laptop turned itself off. However, when I tried to recharge the battery, the battery icon showed "6% available, plugged in, not charging". I contacted the supplier of the battery and they sent me a new one. This showed an initial charge of 93% so, in view of my problem with the previous battery, I decided to try and charge it up to full capacity before letting it run down. But as soon as I tried this the battery icon showed "93% available, plugged in, not charging". So I unplugged the charger and again let the battery run down until the computer turned itself off. I plugged the charger in again but then got "6% available, plugged in, not charging". I have no problem charging the old battery, so can anyone please suggest what the problem might be? I have tried taking out the battery and unplugging the charger and holding down the power button for 30 seconds, but this hasn't worked. Grateful for any advice.
don't know for sure but it sounds like the OEM Batteries you are getting are not 100% compatible with your Model laptop/battery , I'd call the Supplier again ,maybe they have a tip ? or an online FAQ?
I was going to ask about the contacts everywhere being cleaned and refreshed -- however your troubleshooting already did that
Does Acer still sell that battery?
Some OEM's get devious and add technology to their batteries so you can only use battery's supplied by them. Like the chips they add to printer ink cartridges. Do these batteries have a sticker with Acer written on them?
Try this:
Device Manager > Batteries
Uninstall Microsoft ACPI-Compliant Control Method Battery
Restart the machine
Thanks for your replies. I have phoned the supplier of the new batteries (not Acer, who do not appear to have this type of battery on their website) and they cannot provide an explanation. There are no Acer stickers on any of the batteries. I have tried reinstalling Microsoft ACPI-Compliant Control Method Batteryigional battery but that hasn't helped. I note that the original battery is graded 11.1V and the two replacements are 10.8V but I don't know if that is significant. Any further advice would be welcome.
I would return them and try another Supplier while you still can , but others may have other ideas for you.
I suggested uninstall, not re-install......

There's an extended version of those instructions - the same idea, but some additional steps.
Shut down hte machine
Remove the battery - run on AC power only
Device Manager > Batteries
Uninstall Microsoft ACPI-Compliant Control Method Battery
Shut down the machine
Remove AC power
Wait 1 minte
Insert Battery
Connect AC power
Start the machine
Microsoft ACPI-Compliant Control Method Battery should be reinstalled when the machine is booting
But, the .3 volts might be significant - I agree with Kbird
