I'd avoid alkaline batteries. I picked up a high resolution data logger to monitor some long term voltages, and as it had extra channels I hooked up a battery to it. The battery was meant as a sanity check. As it turned out, the battery made a really nice thermometer! It turns out the reference I intended to monitor was much more stable than the battery. But, maybe a battery in an oven may work...
