Compatible replacement for Streamlight Dualie

This lithium-ion battery replaces the original power cell in Streamlight Dualie, Inova T4 (Old Style) and T4 Lights manufactured before 2007. It matches the 68792 and FLB-LIN-7 part numbers and fits the UR611 model. The 3.7 V 2200 mAh capacity delivers 8.14 Wh of energy for reliable operation.

Upgrade from depleted or ageing original cells

When the factory-fitted battery no longer holds a full charge or shows reduced run-time, this 2.2 Ah unit restores the light to its original performance. The jump is worth it for 2005 and 2006 models where the old pack has degraded after years of service. No modification is required because the dimensions of 70.63 x 19.60 x 19.60 mm match the original housing exactly.

Capacity and headroom for regular duty cycles

The 2200 mAh rating supports typical shift-length use on a single charge, making it suitable for daily professional use. It runs out when continuous high-output demand exceeds the cell's energy reserve, so users needing extended operation without recharging should plan for a spare. The black finish and 100 % OEM compatibility ensure a direct fit without adapter kits.

Questions about this item

Will the 70.63 mm by 19.60 mm battery fit the compartment of my Streamlight Dualie Inova T4 (Old Style) UR611?

The cell measures 70.63 x 19.60 x 19.60 mm and is listed as 100 % OEM compatible with the Dualie, Inova T4 (Old Style), T4 Lights (Old Style) and UR611 models that use part numbers 68792 or FLB-LIN-7.

How do I install the 3.7 V 2200 mAh Li-ion cell in my Streamlight T4 (Old Style) without damaging the contacts?

Remove the tail-cap, slide the battery in with the positive end toward the head, and press the cap back until it clicks; the only common error is inserting the cell backwards, which prevents the light from powering on.

When will the 8.14 Wh Li-ion pack need replacing in a Streamlight UR611 used for occasional night shifts?

A 3.7 V 2200 mAh Li-ion cell typically delivers several hundred full cycles; replace it when run-time falls noticeably short or the light dims faster than before.
