Water in the battery compartment and boot (usually) comes from hairline cracks at the roof seems. Till you locate and fix them, remove the drain bungs from both compartments to drain the water. There are a few informative posts on this issue, so use (advanced) search and just search the Gen 2 forums only.

How many miles on the car?

You never said anything about the condition of the battery, just you changed it. With a new one? What are the voltages of the new battery with no load and with a load of the headlights on?

Are all the connections (positive terminal, negative terminal and where the negative ties to the body) clean and tight?

What is the voltage at the front jump point?
