It is normal if a new THINKPAD T40 battery gets warm when being charged or used. However, close attention should be paid if the battery pack becomes excessively hot. This may indicate there is a problem with the charging circuit of the electronic device. So, it is necessary to have it checked by a qualified technician.
New IBM THINKPAD T40 batteries are hard to be charged.
