Question by Tara J: Will a BR-P2 lithium battery work in place of a CR-P2 lithium battery?
Radio Shack does not carry CR-P2 lithium batteries which is what I need, so I was wondering if a BR-P2 lithium battery will work. Both are 6V. It is for a Shimano Auto-D bicycle gear shifter.

Answer by percival.sweetwater
Both are 6v lithium batteries and the dimensions/shape are identical. The BR is Panasonic, and the CR is GE/Sanyo.

Answer by Greco
You can take only normally have 1 carryon bag per person that will fit under the seat or in the overhead storage areas and one personal item such as a purse, briefcase or laptop.
Here’s a link to the TSA website about what’s allowed and not allowed.
They also have a link on the left side of the page for wait times that show how long the average times are to get checked through security. Also you can only have TSA approved locks on your luggage.

Feeding the output of the 7.2 volt batteries through three diodes connected in series and rated at one amp will reduce the voltage to 6.0.Each diode will produce a voltage drop of .4 volts.

Question by mentalfission: How important is it to fully charge a cell phone before initially using it?
Just bought a phone and they recommend charging it for 5 hours before initial use “to get the most life out of your phone”. I remember reading somewhere that due to advancements made in lithium-ion batteries, that this was no longer necessary. Is that true? Can I charge it for 2 hours or so, take it with me to work, and then fully charge it later tonight?
