Where the internal battery delivers minutes of runtime under typical loads, adding external battery packs extends that to hours — useful for sites without standby generators, or where generator transfer time exceeds the standard SMX runtime envelope.\u003c\/p\u003e\n\n\u003ch3\u003eHow External Battery Packs Work\u003c\/h3\u003e\n\u003cp\u003eThe SMX series is designed to accept up to 10 external battery packs in series, connected through APC's standard battery extension cables. Runtime scales linearly with the number of packs attached. Hot-swappable design means packs can be added or replaced without taking the UPS offline.\u003c\/p\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cp\u003eCompatible with APC Smart-UPS X (SMX) UPS units sharing the same battery voltage.
