The current reading on a tester is independent of the battery in the tester. The battery is there to provide a tiny amount of current so you can read the resistance on a circuit in ohms.
What probably happened is that the useage selector switch was in the wrong position when a measurement was made for voltage of other and being in the current position created a short and the current measurement circuit was burned out.
for more details, please follow up with questions/comments

read the manual - your unit cannot measure current
If batteries fail, it may appear that current is dead even if it is not. Note: always test the voltage-tester before using it.
