Battery Exposed?

Hi all,

New here so please forgive my ignorance in asking this question. We recently purchased a 1998 Escort 75 van, bit (quite a bit actually) rough round the edges but the engine seems good. Just a small thing in the realm of things at the moment, but on cleaning the van for the first time I noticed the water running down the windscreen into the long fixed grill at the top end of the bonnet, was in fact running straight into the engine compartment but most impotantly, straight onto the battery. If I look through the grill I can see directly into the engine compartment.

I just wondered if there should be some sort of battery cover or even some kind of deflector that could run underneath the long grill to stop the water running onto the battery and into the engine compartment. At the moment we have the battery covered up with a Tesco carrier bag :o

Many thanks in advance for any replies guys.

Mark
