One common problem is the LS400 battery cables have a connection that corrodes just inside the insulation a few inches from the positive terminal itself. The corrosion forms a high resistance that will allow enough current to pass for the accessories, but not enough for the starter motor. Have the person that checked the battery take a close look at the cables. (I am assuming that he knew how to test the battery voltage correctly).
Question - when you turn the key to "start", is it really "nothing" or do you hear a click or possibly the engine cranking?

"No sound at all" is often caused by the NST.

It's tracing it out...
Key cylinder not working correctly?
Alarm locking it out?
No power to the starter due to corroded cables - does happen.
If attempted jump start makes no difference, then probably not a battery issue, but connectivity could be the problem.

1. You turn the key and you just hear 1 click ( Probably starter )
2. You turn key and hear several clicks ( probably battery )
3. Your turn key and you hear engine trying to turn over ( could be battery, fuel, spark and some other issues).
1 and 2 are the easiest to diagnose. 3 could have you pulling out your hair but should still be easily figured out. The key is to know what condition your dealing with at the moment.

Key statement was, "It was given to me". So likely the problem was already figured out, and is likely the nice and expensive starter motor replacement. Not a fun or easy job on these cars.

If the battery has been sitting for that long without being used (even if on a maintainer), you're better off just getting a new one.
Besides, if there is an electrical issue other than the battery, further diagnosis requires that the battery be fully charged and able to hold a charge.
