New registrants: if you try to register you will get a message that we are not accepting new members. Due to the limitations of this forum software which is not designed to deal with incessant CIA harrassment, we have no alternative but to disable automatic registration, and then we can't change this automatic message. Your account needs to be created by admin before you can post in the forums. Because otherwise, almost all registrants are CIA sock puppets. To get a forum account you need to send a brief presentation email to loohanforum at gee mail dot com, also suggesting a user name. Then we can enable you manually. But before you even do that, take a look around the forum and my site and decide whether you REALLY WANT to join/post, before you jack us around. Most seemingly genuine people who apply fail to even ever log in once to change their password after we go through the work of creating a membership for them. Then we must quickly delete their account again lest the CIA has intercepted their temporary password. And of the few who do change their password, most still never post. Maybe they realize we are too weird for them, I don't know. They get real quiet, never to be heard from again.

GLOSSARY: Sometimes unusual terminology or abbreviations are used that with some luck you might find defined here.

9V battery popped?

9VBat.jpg
Odd thing happened to this battery that was running my protective 30kHz wearable mobius device.
No leakages but it looks like someone ran a blowtorch along it in a couple places. Outer skin only is split in 2 places, and wrinkly overall. Battery is totally dead, 0.01V but i don't know if its lifespan was curtailed.

Re: 9V battery popped?

It is possible. On the clip-on battery connector, the big terminal is large enough to span the terminals on the battery.
I have the battery and coil in a padded nylon belt pouch. I had it in bed with me. I thought it was clipped on but maybe i rolled over and disconnected it inadvertently. In the morning i found the battery was already disconnected.
Something to be aware of. Luckily it did not rupture and blow hot chemicals out.

Now when not in use i store the battery away from the clip-on connector.
