Yes, the batteries do use DC, however if you're using the entire UPS system, the UPS system's INPUT is AC, hence you needing to convert it.

The only way around this would be by-passing the UPS, creating your own recharging circuit, which would regret you to regulate the voltage or current depending on the battery, and feeding directly to the batteries.
