Frequently Asked Questions (FAQs)

1. Can we change battery of scientific calculator?

On the back of each calculator, you can see a small slide with an arrow on it. If you push slightly on this while sliding it down, the slide will come off. Then you can see a small button cell battery which you can replace. Just take it out with a small object like a paper-clip and replace the battery.

2. Which battery is best for calculator?

NiMH or Lithium non-rechargables would be good options. Alkaline batteries can leak and damage the circuit board (I've repaired 2 calculators because of this damage).
