I have a cr2025x1 with international dates and time. Its a calculator and might need new batteries but I can't open the back.

It takes around four hours for a freshly charged main battery to charge the internal backup battery. It you do that and it still doesn't charge it, you need a new internal battery. The fully charged internal battery in most of them will hold the charge for up to 3 weeks with the main battery out of the camera.

Yes, it has an internal button cell battery, type CR2032. You can replace it by removing the calculator's protective cover, and loosening the screws in the back plate. Carefully open the case and do not touch other internal parts. You may use a small screwdriver to aid in removing the old battery.

Insert the new battery in proper polarity and it should snap in place.

The world of compact digital cameras is fast and furious blink and you'll miss the new model. These pocket point and shooters are cram packed full of features that most people neglect to utilize. So it's uncommon for the problem you describe to occur however it's simple and fairly inexpensive to repair. What you need is to replace the camera's internal battery which holds the custom functions and date time settings after the camera has been shut off. Normal internal battery life is greater then five years and a lot of my cameras go ten years before replacement. A camera store not your big box type but one that actually sells cameras and does film and print processing. I don't know where you are to even suggest someone. However at the bottom of the camera where you would place the memory card and batteries there is another slot for the internal battery. This link half way down the page will show the open battery door and where the internal battery is located.

There has been few complaints or problem with this camera except for the very weak internal flash.

Hi there,

Well first of all you can try to reset your calculator, just follow the below steps to know how to reset it -

1. Turn off your TI-83 Plus.
2. Open the battery panel on the back of the calculator and remove one of the AAA batteries. Keep this battery handy, as you'll need it again.
3. Press the "Clear" button, and keep it held down.
4. Put the battery back in and turn on the calculator, with the "Clear" button still held down. When the calculator's screen displays the message "RAM Cleared," release the "Clear" button.
5. Remove one of the calculator's batteries again. This time, hold down the "Del" key.
6. Reinsert the battery and turn on the calculator. Release the "Del" key when the screen reads "Waiting...Please install calculator software now."
7. Use the TI Connectivity cable to connect your calculator to your computer. Run the TI Connect software to reinstall the calculator's operating system. If you don't have an up-to-date copy of TI Connect, see Resources.
8. Turn off the calculator and disconnect the TI Connectivity cable. Remove the AAA batteries, as well as the small, circular lithium battery.
9. Wait five minutes before putting the batteries back in. Turn on your calculator.
Hope it helps ..........

Good Luck!!

Thanks

Your calculator may need to be reset. Open the battery door. There's an internal battery behind a little door with a screw right above the 4 AAA batteries. Take this battery out. Leave it out for about 8 hours then put it and the AAA batteries back in. Hopefully this will solve your problem.

I'm going to quote dsteele04 on this one (he is a user of this site).

1. Switch the GT*RATE SET button to RATE SET.
2. Press the date/clock button to display current time.
3. Enter time wanted using military time. 4:52 p.m would be entered as 16.52 (Note the 16 is followed by . then enter the 52. (ie. 10:45 a.m. would be entered as 10.45)
4. Press the date/clock button again to enter new time.

Just reset mine and is current. If the built in battery needs changed, access panel is on the back. It uses a watch type battery.

never use kodak again!!!

IT MIGHT NEED A NEW INTERNAL CLOCK BATTERY . TAKE OFF BATTERY AND THE LITTLE DOOR FLIPS OPEN . I THINK ITS A CR2525 LET ME NO IF THIS HELPS

Look for the reset button, then remove the batteries - this should fix it.
