This H3KR model comes with an internal 72V battery pack (6×12V/9Ah), giving solid backup time for our critical IT load, and we can extend runtime further with external batteries if needed. The intelligent two‑/three‑stage charging and configurable current (1–12A on H3KRS series) help keep batteries healthy while still charging fast between power cuts. For a 3KVA rack UPS, the balance of built‑in backup and expandability is very practical
