How do you install a battery tiedown and tray?

[stallion]

Ok so my battery doesnt hold charge anymore... been about almost 2 years since I bought the SVX. It didnt come with a tray or tiedown and I didnt know it would affect a batterys ability to hold charge (I used a bungee deal) until I did a search and found it loses charge without a proper tie. Is it really necessary to get a tray? Is there an alternative, like a piece of plastic or something.

Also, how do I install a battery tiedown? I have not the slightest clue where to start.... I tried looking for instructions on here but came up with none. I would prefer a tiedown from kragens or something I can get.. I cant cut metal as I have no tools to drill nor cut, I only have wrenches and such.

can someone help a noob? :O i dont want to blow money on a new batt and have it go out in 2 years.
