Just keep it. Before the battery gets empty, the numbers on the display slowly start to fade, but then you still have about 10 hours of battery life left.
Why fiddle about in the exam with changing batteries...make it a yearly thing to change batteries the week or day before the exam (like a fire alarm battery replacement). I believe my post is the most risk reducing approach in the thread.
