Model Railroading > New TCS KA-1 and KA-2 Run time?

Looking at using TCS's new and improved KA1@KA2 in combo with tsunami 2 and esu micro on some small ho locos. If anyone has used these new keep alives could you tell me roughly how long they keep an atlas or genesis gp series loco with sound and lights on after power loss? Thanks!

Here's a round-about answer: I use the KA-4 in my Tsunami 2 geeps. When fully charged, they stay alive for about 8-10 seconds after power down.

TCS's webste says of the new KA-1's and 2's: 
"Newly-redesigned and coming in at half the size of a KA3, the KA1 will power HO or N scale locomotives with approximately one-third of the capacitance of KA3/KA4 devices (depending on the locomotive and motor)."

So 3 seconds or so??????

About 3-4 is right.   They are the perfect size, in both size and time.  

In my opinion 2-3 seconds is all I need.
This is enough to get over an insulated frog or to let a automatic reversing section react when a train runs across a polarity change.
As to the time factor, it depends on what the decoder is doing, they can keep a light on or a sound active longer if the traction motor is not drawing power.
