A rice cooker machine is a handy kitchen tool that allows you to quickly steam rice without having to boil it in a pot. If the display on your rice cooker flashes or no longer appears, you may need to replace the lithium battery in the unit. The timer and clock display typically run on the battery, while the rest of the unit receives power through a wall outlet. It's important to change the battery for the unit so that you can properly use the timer when cooking your rice.
Turn off your rice cooker by pressing the "Off" button. Unplug the power cord for the machine from your wall outlet.
Plug the rice cooker back in and press the "On" button. View the display to see if a number flashes.
Press the "Clock" button, then press the up and down arrows to change the time on the rice cooker. If the time won't change, the battery needs to be replaced.
Turn off and unplug your rice cooker again. Turn your rice cooker on its side and locate the battery compartment.
Use a screwdriver to remove the screws in the battery compartment or unsnap the compartment with your fingers, depending on the cooker.
Remove the lithium battery and place it into a ziplock bag. Take the battery to an electronic or jewelry store to get the exact replacement, or you can order the battery online.
Insert the new lithium battery into the compartment and close it. Reinsert the screws, if necessary, and then plug the unit back in. The clock on the rice cooker will now work.
