Even in the world of experts there are divergent opinions on which method is best and which can bite you in the end. During my years as a transmission technician with Sprint (formerly Southern Pacific Communications) the word was to _not_ use petroleum jelly as it can damage the jars (cases) of some batteries (2 volt cells, actually). No-Oxide grease was the order of the day.
In the case discussed here, I venture to say that Don's experience ought to be significant and a guiding light. The added virtue is the lower cost. Light oil ought to do the job nicely so long as you don't over use it. 73 de Dick, ka1oz Elecraft K3/100K #859 GAP Titan-DX Vertical G5RV Doublet On 06/17/2013 05:25 PM, Mel Farrer wrote: > It was standard practice at AT&T to clean and coat the large 2 VDC battery > terminals with petroleum jelly.
