I got a new battery for my daughters Dell Inspiron 1501. It is a 9 cell 7800 MAH. I got it on ebay. The charger I also got on ebay last year. It is a model st-c-075-19500334ct, input:AC100-240V~1.5A 50/60Hz Output:19.5V-3.34A. I am wondering because the charger seems to be getting very hot, but the recommended charger on ebay has the same specs. Your help is greatly appreciated!
