Laptop's New Battery stops charging at ~90-92%

The original battery in this ASUS A54C laptop (14.4v, 2600mAh, 37Wh) recently degraded to where it would only keep the unit alive for a few minutes; I normally only use the computer at a desk with AC power, and the system says it charges the old battery to 100% when doing so. [Is it monitoring the voltage?]

Last week I installed a replacement battery of the same specs. (from EBay) but after being on AC, so able to charge constantly for a few days and nights, and after using the system on battery a few times in order to run it down below 50%, the system still stops charging at ~92%. After temporarily reinstalling the old battery, it charged to 100%. Reinstalled, the new battery, it still behaves the same as before. While running on Battery, the system will show the "Time Remaining", it being two or three hours at first, depending on what's open and being done, so the battery at least seems to be good.


In reply to my query about this, the seller said 1) that if the charger (transformer) is over two years old, it should be replaced (it is actually working fine), 2) that I should update the BIOS (??) or change the Power Settings (Nothing I know of in Power Settings is about charging levels, only usage) and 3) I should have the motherboard tested.


Can anyone explain this situation to me and/or give me detailed guidance? Is there some procedure I should try to get the system to reset its battery management program to fit the new battery, or is there something else I'm missing?


I did at one point, while the system was Off, (and AC power disconnected) remove the battery and then hold the On button down for ~20 seconds to discharge capacitors, remove residual charge, or whatever.
