Questions about this item

How often should I replace the 6 V 4.5 Ah battery in my emergency lighting unit?

Plan to replace the SL2678 battery every three to five years, or sooner if the self‑test shows reduced runtime, because sealed lead‑acid cells lose capacity with age.

What limits runtime first during a prolonged power cut — voltage drop or heat?

Voltage drop reaches the inverter’s low‑voltage cutoff before the battery overheats, so usable capacity ends when the cell voltage falls below the UPS threshold.
