Introduction
This provides the steps to replace the internal battery in the JAH-A10A (5.5 cup) Tiger Rice cooker. These steps are likely to apply similarly to other Tiger Rice cookers.
Ce dont vous avez besoin
-
-
Unplug the rice cooker!
-
Place a soft item on the bench, to prevent scratching the lid
-
Remove the four screws from the base. Take note - each screw has a black washer, but the rear two screws also include a white spacer.
-
-
-
Lift the lid off carefully (rotate it from the front to the back). It is attached electrical via cords - treat it very carefully.
-
Take note of the connections onto the main board of the rice cooker. Suggest you photograph these connections before you remove any of them!
-
-
-
-
Remove the two phillips head screws holding the main electronic board in place. The arrows indicate location of the two screws (but they are at the back of the board)
-
Once the board is removed, disconnect all the electronic cords connecting the board to the rice cooker. As mentioned before, ensure you take a photo of the location of the connectors before removing!
-
With the board removed, the LCD panel is exposed. Take care of this and the cavity (as any dirt falling in will cover the LCD panel when re-installed)
-
-
-
With the screws removed, the main board assembly can be lifted out. It is connected to the LCD panel and buttons by flexible cable, so be careful working on the board.
-
The battery to be replaced is shown in the picture. As indicated, it is soldered onto the board.
-
The battery removed from the board is shown for reference.
-
-
-
The board must be removed from the assembly.
-
Screws are indicated in the picture.
-
-
-
The battery must be removed by desoldering the two positions shown. Take note of the polarity of the battery before removal.
-
Desolder the points and remove the battery.
-
Solder the new battery in place, maintaining polarity.
-
New battery installed here - the new battery had a plastic ring around it. The tabs may be in slightly different positions and may require manipulation to fit into the existing location
-
Once the battery has been connected, check the display panel to see if the clock is flashing - this will indicate the battery is connected.
-
To reassemble your device, follow these instructions in reverse order.

Pro tip, order a CR2450 battery holder with 20mm pin spacing and solder that in instead. Costs $1. Then use a normal CR2450 button battery, they are cheaper and can be replaced easily next time.
My model was slightly different JBA-T10A.
After removing the 4 base screws I had to lever the base off with a flat screw driver.
No need to disconnect the power wires, the power socket slides out from the plastic base.
3 screws hold the circuit board.
Hi Colin, are you able to post a link to a website that you got the battery holder from?
I got a holder and Panasonic battery on eBay.

Also you could use a cr2477 as it has same diameter but larger capacity.

Thanks for the suggestion about the battery holder. I’ve just replaced the original battery in our ~6 year of rice cooker. I was able to just reflow the existing solder so it was an easy swap. One resistor ended up slightly under the battery holder so the holder is slightly canted, but that won’t be a problem.
My model is also different: JBA-A10U. I found the circuit board is originally designed to install a battery holder, but, probably for cost cutting, a welded battery is attached. From a manufacturing standpoint, it looks easier to install the holder, though.
I installed a battery holder: 534-1053-BH (Keystone Coin Cell Battery Holder, MFG Part No.: 1053 ). This fits perfectly.
Thanks for the instructions. Very helpful. One other tip that might be even easier for the battery holder is a button cell holder with wire leads (ex: https://www.amazon.com/gp/product/B074FZ... ). These holders are made for 2 batteries - but the adivce for one battery use is to put a penny in the other slot.
Removed my battery and used a battery holder for AA batteries. Much easier for me to change battery when needed.
Do you guys know where to find a center sensor for this model?
I did something similar on my old Sanyo EJC-B355. Fortunately, there was a cavity at the back of the case big enough to hold a pair of AA batteries in a holder. I clipped the leads to isolate the onboard coin battery and soldered on leads to the batteries in the holder. That was quite a few year ago and it's still working.
Unfortunately, the cooker has now started to leak somehow, so water collects around the rim of the pot and sometimes runs down to the counter. so now looking into a new cooker. But as far as I can tell they ALL have that onboard battery. How do they get away with that? It's like buying a new Chevy and having to send it to the crushers when the tires wore out!
Had the dead display if not plugged in, but rice cooker still worked if i plugged it in, manually set the time and chose my cook settings. Opened the case according to instructions above - easy - could readily see battery in display. Removed display unit (3 phillips screws) - easy. The battery was held in place by a thin strip of meal on the top and the bottom. Each strip has 2 small points of electric welding holding it to the battery. I grasped the battery firmly with needle nose pliers and used a rigid pocketknife blade to wedge in between the metal strip and the battery and applied a twisting motion to ‘pry’ the metal strip off the battery (no soldering gun needed). Repeat for back. I happened to have a spare 3V lithium cell for my garage door opener - i slid it in between the two metal strips as a test and it worked. Then I straightened the strips and crimped them into a shape to hold the battery - I slid a strip of duct tape under the battery and wrapped it around securely - all good.
