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?

|25:54||Topic||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.)
|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.
