power supply - Using wrong adaptor with same V but wrong amps with my laptop

I have a Toshiba Satellite A200 1-GH. My sister's old laptop was also a Toshiba. The adaptors were mixed somehow, and I've been using the wrong adaptor for a very long time. I've realized this when my computer could not work without the adaptor plugged in. When I checked out the voltage-amps values, the values on my computer were 19V-4.7A, the values on the adaptor were 19V-3.42A.


I bought a new adaptor corresponding to the values written under the computer immediately, but I was wondering if the battery should also be replaced? If so, what happened to the battery technically that made it useless any more?
