Replacement NiCd Stick for Streamlight Models

This 6 V nickel-cadmium battery stick replaces the original pack in Streamlight SL-20XP LED, UltraStinger and Super Stinger lights. It delivers 1600 mAh capacity in a single 5-cell configuration measuring 8.45 inches long by .91 inches wide. The pack is built to meet or exceed the original equipment specifications.

Upgrade from depleted original packs

Swap this stick in when the factory NiCd cells no longer hold a charge or show reduced runtime. The jump is worth it if the light still functions mechanically but the battery has aged past useful capacity. It is not for users who need a different voltage or chemistry such as lithium-ion.

Simple drop-in installation

Remove the old stick and slide the new one into the flashlight body; no soldering or tools are required. The only common issue is reversed polarity if the stick is inserted backwards, which prevents the light from operating. Ensure the contacts align with the markings on the housing.

Questions about this item

What are the length and width of the 77175 battery stick so I can check it fits my Streamlight?

The stick measures 8.45 inches long and 0.91 inches wide, or 218.19 mm by 22.22 mm, matching the original Super Stinger and Ultra Stinger packs.

How do I install the 77175 stick and what step do people often miss?

Open the flashlight tailcap, remove the old pack, insert the new 77175 stick with the positive end toward the head, then fully charge it before first use — skipping that initial charge is the common mistake.

When will the 1600 mAh NiCd pack need replacing and how do I tell?

Expect roughly one year of regular duty; replace it when run time drops noticeably or the light dims quickly after a full charge, as NiCd cells lose capacity with age.
