Dual Lite 3901 compatible battery

This 6V 4.5A sealed lead-acid unit replaces the Dual Lite 3901 cartridge in emergency lighting systems. It arrives new and ready to install without additional wiring. The high-rate discharge design supports the rapid power delivery that emergency fixtures require.

T1/F1 terminal constraint

The battery uses T1/F1 faston terminals, so it fits only equipment designed for that connector spacing. Buyers whose devices need a different terminal style or a higher amp-hour rating must select another part.

Questions about this item

How long will the 4.5 Ah capacity run my emergency light during a power cut?

The 4.5 Ah rating shows how much charge the battery holds; actual run-time depends on the light's power draw and the battery's age.

What does the T1/F1 terminal type mean for installation?

T1/F1 refers to the faston tab size on the battery terminals; check that your unit uses the same tab width before fitting.
