Can I use a rechargeable 9-volt battery in an old vintage LED calculator?
i have an old 33 year old TI-30 calculator that works perfectly, but it takes a 9 volt battery. I want to save money on batteries and use a 9 volt rechargeable 175mAh 8.4 Volt Nickel Metal Hydride to be exact.
The owner’s manual clearly says to only use Alkaline non-rechargeable batteries, but this was 33 years ago and I assume batteries are different now, especially rechargeable ones.
Can i use it or not?
Yes you can. I had a TI30 I used on a rechargeable 9v battery fine.
