I've just replaced the battery, bought on eBay, in an Acer 5920 running Win 10 Fall upgrade. Although I followed the charging instructions the laptop simply shuts down after about an hour of battery use without any warning.
Running the battery report throws up odd things. When first run on the new battery the report detailed the battery info as follows (which coincidentally is exactly the same as the original battery, even the serial number):
SERIAL NUMBER 22180
DESIGN CAPACITY 48,840 mWh
FULL CHARGE CAPACITY 14,652 mWh
After swapping the batteries about the report showed the new battery to be a Sanyo as follows:
SERIAL NUMBER 63331
DESIGN CAPACITY 47,520 mWh
FULL CHARGE CAPACITY 46,991 mWh
Note the Design Capacity, it should be 56Wh (56000mWh).
The laptop then threw a wobbly and I lost the user account, which is the subject of a separate appeal the BC community. Losing the account also appears to have wiped most? of the battery history prior to it happening.
Today's first battery report on the new battery shows the original battery details again. After running the laptop for about an hour the laptop powered down without warning. Running it now on mains with the new battery installed the battery report shows the Sanyo details again.
The last battery report shows:
START TIME STATE SOURCE CAPACITY REMAINING
20:17:49 Active AC 4 % 544 mWh
20:32:53 Suspended 100 % 14,652 mWh
20:34:11 Active AC 100 % 14,652 mWh

07:29:45 Active Battery 312 % 45,721 mWh
08:25:00 Suspended 312 % 45,721 mWh
08:41:59 Battery changed AC 22 % 10,141 mWh
08:41:59 Active AC 22 % 10,141 mWh
10:05:36 Report generated AC 68 % 31,806 mWh
Note: The 08:25 entry is when it powered down without warning and the entry for battery change is wrong because I did not change the battery. Also note the 07:29 and 08:25 entries show capacity at 312%???????
Why does the laptop power down with out warning and how do I fix this?
Why does the battery report keep changing battery details and how do I fix this?
The short life of the new battery is also an issue which I may have to take up with the supplier if its performance does not improve.
Any help with this will be much appreciated.
