This is probably rather simple, but I am having trouble and am asking for help.
I have a "mini lamp" (miniature light bulb) that I bought at Radio Shack, 1.5 volts - 25mA. I need to light it with a tiny battery so I've been looking at hearing aid batteries and small coin cell batteries. I need a battery that can fit into a spot that is 5/8", so I tried a hearing aid battery #317 23-816 1.5v. That didn't work, the light was extremely dim. I added another of the same battery by stacking (in a series), still too dim but better. I then tested it with a 3v CR 2025 lithium coin cell battery just because and that worked perfectly... but that battery is too large (it's about the size of a nickel). So I then tried a 3v CR 1025 23-791, too dim and it just dims out to nothing in about 1-2 seconds, added another, same, too dim and it turns off in 1-2 seconds.
What am I doing wrong?
And why does the smaller 3v battery (3v CR 1025 23-791) not keep the bulb lit? Even when I add another?
Thanks so much for any help you can give!
