Press the 2nd button on your calculator, then either the ▲ arrow key to darken the display or ▼ arrow key to lighten the contrast. Sometimes after changing your battery your calculator home screen contrast may be very dark or very light and you will have difficulty seeing characters on the screen. If you were receiving a warning message about low batteries before changing the batteries, you should no longer see this message. Once you have finished replacing all the batteries, place the battery cover on the back of the calculator, then power up the graphing calculator by pressing the ON button. Also, never mix rechargeable and non-rechargeable batteries. For best results, don’t use both old and new batteries in the calculator.

Ensure that the + and – ends are placed correctly. If you remove all batteries at once and then replace them with new batteries, you run the risk of losing your calculator programs. The best way to replace the batteries is to remove each battery individually, leaving the other three batteries intact, and replacing the battery you removed with a new battery, repeating for each of the four AAA cells. Remove one battery, replace with the new battery, then proceed on to the next battery.

You can also back up the applications and programs on your computer using the TI-Connect software and calculator connector cable, explained here.You can archive your graphing calculator programs and applications, covered in more detail in these articles for the TI-83 and TI-84 Plus and the TI-89 or Voyage 200.Before changing the batteries, it is a good idea to backup any calculator programs you have to avoid potentially losing them, although with good practice this is usually not an issue.

In most cases, you will only need to change the set of AAA batteries. On the TI-83, TI-84, and TI-89, if you look at the backside of the calculator and remove the battery cover, you will notice a small cover held in place by a single screw (#1 in the image to the right) which houses the backup battery, and four visible AAA batteries (#2). Your Texas Instruments graphing calculator has two sets of batteries: a standard set of AAA alkaline batteries for day to day calculator use, and a lithium or silver oxide backup battery which is used for powering the calculator’s memory when the AAA batteries are removed. Notice the location of the backup battery (1) and standard AAA batteries (2) on this TI-83 Silver Edition
