Gel Cell and Lithium Ion and Christmas

Gel Cell

Song: 00:00

"Mrs. Santa Claus" by Jingle Punx, from the album "Coal"

Intro: 01:35 Christmas time in North Texas.

Feedback: 02:30

John, M0JFE, likes the show and asks for a show about packet radio.

Thanks, too, to Bill at SolderSmoke for the mention.

Damon, NN7B, listens to both shows, and asks how sealed lead acid batteries compare to nicad and nimh for a grab-n-go kit or mobile station?

Donations: 07:54

Thanks to David, no callsign given, in Pleasonton, CA, and
Jerry, KD0BIK, of the Practical Amateur Radio Podcast.

08:48 Different music format this time - Christmas music.

10:40 Take a look at the Cafe Press store for Resonant Frequency merchandise.

Song: 12:42

"Goin' On a Date With Santa" by Dr. Elmo, from the album "Up Your Chimney"

Buzzword: 16:16 Superheterodyne, presented by Tim Sutton, KI6BGE.
http://en.wikipedia.org/wiki/Superheterodyne_receiver

Song: 22:34 "Don't Want No Bones for Christmas (I Want An Electric Guitar)" by Paul Austin Kelly, from the album "Don't Want No Bones for Christmas",

Topic: 25:54 Batteries: Gel cells and lithium ion.

  • Gel cells are a type of valve-regulated, lead-acid (VRLA) batteries. They have a pressure-
  • relief valve to allow venting of hydrogen during overcharging, and a gelled electrolyte. They
  • have a greater resistance to extreme temperatures, shock, and vibration than typical wet-cell
  • batteries like the common car battery.
  • (Contrary to what Richard says, hydrogen is a colorless, odorless gas. The "rotten egg" smell
  • from an over-charging car battery is due to the creation of hydrogen sulfide gas, H2S. -Ed.)
  • http://en.wikipedia.org/wiki/Hydrogen_sulfide
  • 36:04 Lithium Ion batteries.
  • Most of the newer electronics, like laptops, handheld radio, etc., has Lithium ion batteries
  • due to their energy to weight ratio, and no memory effect. They also have a low self-discharge
  • rate and are lighter than other types. Their service life depends on the time of manufacture,
  • regardless of number of charge/discharge cycles. The internal resistance is higher than most
  • of the other chemistries.

Song: 41:44 "Send Me a Wife for Christmas" by Dr. Elmo, from the album "Grandma Got Run Over By A Reindeer",

Conclusion: 44:42
Listen to Linux in the Ham Shack, too!
Happy Holidays!

Closing song: 46:42 "Jingle Bells (Dan the Automator Remix)" by Dean Martin, from the album "Christmas Remixed -
Holiday Classics Re-Grooved"
