I kinda fell in love with the Power Bug (Lithium - long life 9v) since I found a couple in the battery cavities of my Ritter Roya a few years back... I think Jens was testing them & shipping instruments with them... But they disappeared from the market...
I switched to the Ultralife Lithium 9v versions (essentially the same cells in an aluminum housing)...
Recently I discovered:
U9VL / U9VL-FP - NSN 6135-01-369-9792 : 9-Volt Batteries - Ultralife Battery & Energy Products | Ultralife Corporation
plastic housing version - the theory behind the Power Bug's plastic case was to reduce or avoid "noise" in active musical instrument circuits, medical & wireless applications - not sure if the science adds up?
Anyway - I still like these babies & the longer life is a huge bonus in some of my active basses that don't have easy access to the battery compartment...
Anybody have any Good or Bad experiences with Lithium 9v's?
