bent crank ?

My 2 cents on batteries, for what it is worth (not much!).

I suspect that in the old days of vented batteries and porous tops, if you set one on cement that had a high calcium or lime content, the calcium or lime would neutralize the battery acid through the air......this is why in the aviation industry we never store or service lead acid batteries in the same room as nicads.......nicads are basic, lead acids are acidic and they will neutralize each other.

As far as I am concerned, with today's sealed batteries there is no issues with placng them on cement. I do it all the time and have yet to see a battery drained.

And if a crank can bend just by sitting there on its side....it must be maleable, like plasticine.....but they are not they are brittle like glass which is why they break, not bend when abused.

I don't buy it.
