Is it harmfull to GRP? On my boat the batteries sit on a moulded in shelf that wouldnt contain all the acid should one crack.Should I invest in plastic battery boxes or not worry on a boat thats survived since 1973?

[/ QUOTE ] Grp is not affected by dilute acid but i'd neutralise any spills and clean up as soon as possible.
Plastic battery boxes have serious disadvantages in that they can prevent the dispersal of gasses (H2 and O2 ) releasd from the battery (Ref recent posings by boatmike) But one with the top left off, or vented, would contain any spillage nicely.

Excuse my ignorance Vic .What should I neutralize the acid with?

proper battery boxes are not air tight, designed this way to allow gasses ( minimal amount occurs) to escape to air

Ideally an alkaline like a baking soda solution (I think!) but lots of water will do - there will be plentiful supplies of it nearby unless the tide is out.

Would some of this do the job?

If you use seawater,chlorine gas will evolve. Killed a lot of submariners in WW2. An alkali is best- soapy freshwater.

[/ QUOTE ] As Searush says bicarbonate of soda aka sodium bicarbonate , sodium hydrogen carbonate.
Washing soda made up as a solution.
For very small spillages copious quantities of seawater as it does have some natural alkalinity.
Rinse out after afterwards of course.
To put some perspective on it it will take about 900g of bicarb or 1500g washing soda crystals to neutralise a litre of battery acid.
I'm not going to do the calculation for seawater at a quarter to midnight but it'll almost certainly be enough to sink your boat several times over

[/ QUOTE ] Bollocks. You need an oxidising agent to get chlorine gas from sodium chloride.
Electrolysis if it comes into contact with the electrics will produce chlorine, also if it gets into the batteries.
