Prolonging the Life of Your Calculator Battery
Once you've found the right battery for your calculator, keep it working longer with these battery life tips.
- Remember to power down - If your calculator has an on/off button, remember to power down your calculator when it's not in use. Some calculators also offer power-save options that can turn off the calculator or the screen after a certain amount of time.
- Avoid mixing batteries - Batteries perform best when they're the same age and come from the same brand. If your calculator requires multiple batteries, replace all of them with fresh batteries to get the most from your device.
- Practice safe storage - Avoid leaving your calculator in sunny or warm places where it can overheat. Try to store it somewhere cool and dry, or remove the batteries when the calculator is not in use.
