    Can I mix old and new batteries in a smart UPS?
    No, you should not mix old and new battery cartridges within the same Smart-UPS system. As VRLA (Valve Regulated Lead Acid) batteries age, their capacity is reduced. Your Smart-UPS batteries are connected in parallel and all batteries are charged at the same rate.
