Vintage Led Calculator
¿I can use a 9 volt battery in an old Led Calculator harvest?
I have an old 33, 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 175mAh rechargeable 8.4 V nickel metal hydride to be exact. The Instruction Manual clearly states that only the use of non-rechargeable alkaline batteries, but it was 33 years ago and I think the batteries are different Now, especially the battery. ¿I can use or not?
Yes you can. I had a Ti30, I used a fine cell 9V battery.
