How To Change Battery

Changing the battery in your Casio SL-200TE calculator is a straightforward process. Here's what you need to do:

Materials:

Small Phillips screwdriver

Replacement LR44 button battery (also known as AG13)

Steps:

Turn off the calculator. Make sure it's completely powered down before you start.

Locate the battery compartment. It's usually on the back of the calculator. Look for a small panel held in place by a screw.

Use the screwdriver to remove the screw. Be careful not to lose it!

Lift the panel gently to open the battery compartment. You should see the old battery inside.

Carefully pry out the old battery. You can use your fingernail or a blunt object like a spoon handle.

Insert the new battery into the compartment. Make sure the positive (+) side of the battery is facing up.

Replace the battery compartment cover and tighten the screw.

Turn on the calculator. It should come to life with a fresh battery!

Here are some additional tips:

Make sure you're using the correct type of battery. The Casio SL-200TE requires an LR44 (AG13) button battery.

Don't touch the metal contacts on the battery or the calculator with your bare fingers. This can cause the battery to drain more quickly.

Don't dispose of used batteries in the trash. Check with your local municipality for recycling options.

The Casio SL-200TE is a small calculator that runs on solar power as its major source of energy. It also has a rechargeable backup battery that is designed to give power when there is insufficient light for the solar panel. If you're having problems with your calculator and feel the backup battery needs to be replaced, you are requested to take the following steps:

Before you begin, make sure you have a compatible replacement battery for your Casio SL-200TE. To determine the suitable type of backup battery, see the user manual for your specific model.

Before doing any maintenance, make sure the calculator is turned off. If it's turned on, use the OFF button to turn it off. Look for the battery compartment on the calculator's rear. It is frequently fastened with a tiny screw or latch. If there is a screw, carefully loosen it and remove it with a little screwdriver. To open the battery compartment, press or slide the lock.

To reach the backup battery, gently open the battery compartment. Inside the container, locate the existing backup battery. A tiny button-cell battery is often used. If the backup battery is removable, carefully remove the old battery with a non-conductive implement such as plastic tweezers or your fingertips. Take note of the battery's orientation (both positive and negative sides). Insert the new backup battery into the right polarity compartment, matching the positive (+) and negative (-) marks. Close the battery compartment carefully and secure it by tightening the screw or closing the latch. Check that the calculator works properly by turning it on. If so, your battery replacement was a success. Place the calculator in a well-lit location so that the solar panel can replenish the backup battery.
