A well designed UPS will see the higher CEMF and refuse to charge a higher load as even the OEM batteries can fail and simulate the same results. That is simply nonsense. The charger is current limited because high rate will damage small batteries. A large battery will charge slowly. For safety each pack should be separately fused. One concern is the inverter heat sink. It may be too small for extended run time, relying on quick shutdown before the inverter overheats. A major concern regarding small UPSs is the shoddy design, and even shoddier quality of parts and assembly. Do not rely on small cheap UPS to power a critical device without rebuilding the UPS.
