Suggestions

Check the power source.

Check the battery contacts. If available, try another battery and ac adapter.

Move the computer away from any nearby heat source. Unplug the ac adapter and allow the battery to cool down. Check for blocked air vents.

Check the power source.

Make sure main battery is fully charged. If not, secondary battery will not charge.

Check contacts on second battery.

The Time Remaining is an estimate based on how quickly the computer is using power at the moment. It therefore depends on the current task, and assumes that power will be used at the same rate until the battery runs out. So, for example, if the computer is performing a task requiring a good deal of power (such as reading from a CD or DVD), the value will probably show too little time remaining.
