Unless it is a sealed battery, which is hard to tell from that listing alone, that is a no go for in car/trunk use. Under hood or in the truck bed would be... ok.
Why not just buy a decent battery and quit fucking around with this $30 battery shit.
Do you buy $30 amps or a $30 HU? If you just answered yes, then I change my answer to yes buy the battery and put it in the seat next to you. //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif
