Leaking battery acid

I'm getting ready to buy some batteries and was just planning on going with Walmart units.

I'm worried about acid leaking in my freshly painted battery box. Do you guys have a solution for this or is there a way to prevent it?

I was thinking about some plastic tray liners or coating for the tray. Any other ideas?

Thanks.

I've read about these but can't personally vouch for them: http://www.batterymat.com/ Seem to be available through JC Whitney: http://www.jcwhitney.com/acid-neutraliz ... 06087.jcwx, Battery Mart http://www.batterymart.com/p-battery-mat.html, Amazon, and many others. Reviews are positive on the two I linked and on Amazon.

works well. cheap too.

I also lined the entire interior battery box and underside of lid with asphaltum. Seemingly the closest equivalent that was coated within my box prior to dis-assembly.

Thanks guys.

I'm assuming the asphalt stuff is the thick black stuff like I use to line my swamp cooler sump. I'm usually into function rather than fashion but in this case I don't want to put that stuff on my new paint job.

I'll look into the pads.

I’ve had no luck with using standard lead-acid batteries in terms of stopping corrosion. Even when you line the boxes with plastic or asphalt (I've tried both), the acid fumes have a way of getting through the smallest defect. One choice is to flush the boxes regularly with a weak solution of baking soda/water. Battery-mat helps, but a lot of damage is from gaseous leakage, not liquid H2SO4.

My time is more valuable than all that messing around, so I’ve gone to AGM sealed batteries; Optima 51R (Honda Civic). I do keep a set of 2HN’s for show. I got two 51R’s from AutoZone for $320+tax.
