Zojirushi rice cookers cook rice perfectly. These appliances can also steam vegetables, meats, dumplings, and other foods. Here, we will discuss where the battery on this device is located and what it does.

Your Zojirushi rice cooker battery is located underneath your machine. It is soldered in place and can be difficult to replace. If your rice cooker clock no longer keeps the correct time or your delay timer doesn’t work correctly, it may be time to replace the battery. 

Does My Zojirushi Rice Cooker Have A Battery?

Zojirushi rice cookers contain a lithium battery. Zojirushi batteries last between five and ten years. After that time, you may need to replace the battery. You can contact a Zojirushi service center or do it yourself. 

Is The Battery Replaceable?

You can replace the battery yourself if you’re an experienced repair person. If you lack experience, it’s best to contact a repair shop. The battery is soldered in place, so if you decide to remove it, you’ll need a soldering iron and steady hands.

Where Is The Battery On My Zojirushi?

Zojirushi batteries sit underneath your machine. To access the battery, remove the screws on the bottom of your rice cooker. Then, use a flat screwdriver to unclip the tabs holding the base in place. Underneath the bottom board, you’ll find the circuit board that contains the battery. 

You’ll need a soldering iron to remove the old battery and secure a new one inside your rice cooker. If you don’t have experience using a soldering iron, take your appliance to a repair shop or buy a new rice cooker.

What Does The Battery Do?

The battery inside your Zojirushi rice cooker powers the clock and the timer while the appliance is unplugged. A working battery is crucial for the delay timer. The delay timer won’t function properly if your rice cooker can’t keep accurate time. 

The battery doesn’t power your rice cooker. If your battery is failing, you can still use your rice cooker. You will, however, need to reset the clock every time you plug in your rice cooker.

Zojirushi Replacement Battery Cost

Zojirushi replacement batteries typically cost between $7 and $15. Lithium batteries are widely available from Amazon and other stores. The batteries are generally affordable, but only some people have the expertise to replace them. 

Signs You Need A New Battery

If you notice any of these signs, you may need to replace the battery in your Zojirushi rice cooker.

  1. The clock no longer shows the correct time. 
  2. The delay timer fails to work correctly.
  3. The display shows multiple zeros (000). (This may only be true for some rice cookers.) 

If your rice cooker isn’t cooking correctly or is drying out your rice, the issue probably isn’t your battery. It could be one of these issues

3 Ways To Help Your Rice Cooker Last Longer

These tips may not extend the life of your battery, but they will help your rice cooker last as long as possible. 

Measure Your Rice And Water Correctly

Follow the directions that come with your Zojirushi rice cooker. Use the measuring cup to measure rice, then fill the inner pot with water to the matching line. The measuring cup that comes with your cooker is equal to ¾ cup rather than a full US cup.  

Clean Immediately After Cooking

After using my machine, I always remove all parts of my rice cooker and clean them with hot, soapy water. Then, I let them air dry before storing them in my rice cooker.

Store In A Safe Place

Most Zojirushi rice cookers don’t take up much space. Rather than leaving your appliance plugged in on your counter, unplug it and store it safely. I keep mine on a shelf in my kitchen so I don’t accidentally bump it or get it dirty. 

Final Thoughts

Zojirushi batteries last 5 to 10 years on average. You can replace the battery in your Zojirushi rice cooker if you have experience repairing appliances. If not, contact Zojirushi or take your rice cooker to a repair shop if you’d like to replace the battery.
