DIY Change Casio Scientific Calculator Battery

It is quite surprising that there are some people who don't even know how to do basic maintenance or basic repairs of the stuff they have. You spoilt brat you. Ahem. That includes changing batteries of their electronic devices.

Fret not as the resident handyman aka jack of all trades at BenardCometh Revelations will show you how to DIY change the battery of your Casio Scientific Calculator. If you have one that is.

Why Casio Scientific Calculator? Well, it is common and being common means a lot of people own one. Then there is this perception that Casio Scientific Calculator is like the Ferrari of calculators, sort of. Or maybe not.

Anyway, yours truly owns one, In fact he owns a couple of em Ferrari. Changing batteries should not differ much from the different brands of calculator.

For those thinking, "ha I own a solar powered scientific calculator you morons!!!!". Well, good for you. Good for you. -_-"

Lets get on with it shall we?

The only tool you will need is the Philips Head Screwdriver and of course the replacement battery. I got a whole lot of em at some discount store for quite cheap. RM2 for the lot. Cheap stuff.

Batteries


Alright, take your calculator out and make sure you give it a look through to identify where the battery compartment is located.

In my Ferrari case ahem calculator case, flip back the calculator and the battery compartment is located at the top back with two screws fastened to it.

The battery compartment


Unscrew the screw by unscrewing it with the screwdriver. Ha, a mouthful. Ahem. Back to the post, after you unscrew the screws, open up the cover by sliding it upwards then the battery shall magically reveal itself to you.

Proceed to pick out the dead battery and put in a new one. Of course the battery must be dead already, if not why are you even changing the battery? Just for fun is it?

Put in new battery


Put back the cover and screw on the screws by using the screwdriver. **screws**.


There you have it and congrats for changing the battery all by yourself. Be proud of yourself and give yourself a pat on the back.

You big boy you.

You big girl you.

  4. For Casio fx-991MS, after taking out all 5 screws, you can take off the back cover by sliding it up, instead of lifting it up.

  8. Hi. My Casio fx-115n now only works under direct sunlight. I suspect the battery (lithium GR927) needs replacing. The instructions say take to retailer but can you advise how to change it myself? Many thanks. Mark
