Anodized parts?

Should be. The acid your using will give you a sting, but if you wash it off it should be fine. Generally you can take the top off to fill them up with distilled water if you ever need. That was the case with the Nascar batteries (long story), and I think most batteries ought to be like that.
If not, then drill a hole near the bottom, drain the acid into the plastic container, then extract the lead.
The acid will be about 30% w/w so you can happily dilute it some what. If you have some nitrile gloves and safety specs it might help (just in case) and putting on a lab coat/something that isn't absorbent and you don't care if it gets ruined.
Oh and don't intentionally drip the acid on and then proclaim it doesn't hurt, only to have a permanent burn mark about 10 minutes later (a friend discovered the joy of chemistry at uni)

Sounds do-able I guess, i'm about to nip out to pick some parts up from the laser cutters anyho so i'll drop by the skip on the way back and see if I can salvage a battery on my journey.
Just put Aldrich's number into my mobile as well, will give them a bell whilst i'm out n about.
Shall report back shortly!

I ended up with something a bit more corrosive on my lab coat, which now has a hole the size of the grand canyon in one sleeve and right across the chest...not great.
Also, never mix diethyl ether with a flame. It might seem like a good way to clean the glasswear and dispose of solvents, but it also makes really big flames.
Another chemistry no-no is to overfill a cup full of LN2 then spill some over your hand. It doesn't freeze your hands off, but it does sting a bit.

Should be able to anodize half of London with that thing 
Anodizing doesn't require that much energy so this should certainly do the job. The positive and negative poles have different electron charges and putting them both in a glass/bowl/anything of distilled water should anodize anything in the water.
Ouch, I've forgotten quite a lot of those chemistry classes

How big were the parts you were anodising though?
Btw, sorry for hijacking your thread, i'll make a new one if you wish.
Just been out and drained the battery, can see all the lead plates inside now it's drained, just need to figure out how to get this casing open... dremel it? lol!?

nope still there, you faffing nutjob

If you undo the bolts on the top, does that get you anywhere? 12V should be fine, the difficulty will be not applying too much current (high voltage + high current = very hot). That shouldn't be too difficult really tho. Make sure to filter that sulphuric acid because it looks like its got a load of stuff in it which might (probably won't) colour the aluminium a tasty **** brown
Just tried dremeling it, cut a big square in the red section on the top and then had a change of plan, gonna knock it onto its side and grab the hacksaw, take all that top edge off (just above the label).
Need to mix up some bicarb and water though, dont fancy tipping it on its side and having sulphuric pour all over the garden...hehehe!

Right hacksawing through the top didn't work either, the plastic is solid in the centre.
Adopted a new approach in the form of dremeling the entire thing to kingdom come...
Got both ends off, gonna get both the sides off tomorrow then I "should" be able to retreive the bar.
