You could also use the lamp to drop the pack voltage down to under 10V and see if the roomba takes longer to charge the battery. Don't discharge too far or you could damage the roomba.
That is exactly what you want to discover. If while charging the battery gets warm is an indication that the internal Roomba charging system is functional. There is a portion of the Roomba Built In Tests that will also charge the battery and the result you want to receive is a warm battery. Those test steps can now be ignored since you have proven that the Roomba charging system is functional. Again it would appear that you have a duff battery.
