The best choice for operating at temperatures around 30-32 degrees Celsius in a data center battery compartment is the nickel-cadmium battery. Nickel-cadmium batteries are known for their excellent performance in a wide temperature range and have a high tolerance for elevated temperatures compared to other battery types. This characteristic makes them suitable for environments, such as data centers, where temperature control can sometimes be challenging.

Nickel-cadmium batteries also feature a robust design that enables them to handle charging and discharging cycles effectively, which is an important aspect in data centers that require reliable power backup. Additionally, they do not experience issues like thermal runaway, which can affect other battery types when exposed to higher temperatures.

While sealed lead-acid batteries can perform adequately under certain conditions, their lifespan and performance can be significantly reduced in higher temperatures. They are also more susceptible to issues such as gassing and capacity loss over time under elevated heat conditions. The flooded cell option may not perform well in confined battery compartments due to maintenance requirements and potential electrolyte spillage, making nickel-cadmium not only a suitable choice but also a safer one for this specific temperature range.
