vaseline, and obviously you warm weather folks need the grease.
I think this affects the battery sizing debate too: if I size a battery for 4
days storage, it only has 2 or 3 days of storage in really cold weather.
I've seen that leakage to ground on almost all flooded cell batteries. A
battery expert told me it was a fine mist of battery acid that clanged to the
case of the battery and caused this few milliamps of short.
The only systems I've seen that didn't have this were either very new/ clean

The Surrette 2v L16 is one single cell built in a case the size of a
standard L16. I've seen other 2v products come out which are really just
three 2v cells with internal parallel bus bars, rather than the standard
series connections. That means you don't get the real benefits of using

I rarely use grease or vaseline unless it proves necessary. I have
