Why I abuse batteries was: trojan battery cycle [RE-wrenches]

[Drake Chamberlin]

<x-flowed>

Hi Travis,

It seems that the specific gravity is affected by bubbles in the 
electrolyte during charge.  I've heard this from others, and it 
appears to be true from my observation.   Does anyone have any data 
on this effect?
