Hello,
I got a Motorola NiMH battery for a Talkabout radio. It is 3.6 V, 1400 mAh and very close in size to the Classics power pack.
I checked its size on my HP-65. Acouple pads in the sides (like tha batteries Mike Hoskins sells) and it fits in the battery compartment. But...
There is no indication on Classic calculators battery pack polarity, and I am afraid of any damage due to wrong installation.
Now the questions.
Is it safe to use this battery on a Classic calculator? Which terminal is positive and which is negative on the calculator?
Thanks in advance.
