RE: [PSUBS-MAILIST] Optima Battery Data

[irox <irox@ix.netcom.com>]

Hi,

the chlorine gas is a product of the electrolysis of sea water, the
battery does not need to be exposed to sea water, only the electrodes.
Running a current between to relatively close electrodes immersed in sea
water will produce hydrogen gas, oxygen gas, chlorine gas and coustic
soda which form as percipitant in the solution. 

Cheers,
  Ian.
