Streamlight batteries 75175 and 75375 are the same accessory battery for Streamlight Stinger Flashlight. The difference between them is the Streamlight 75175 is a NiCad battery while the 75375 is a NiMH battery.
Though to the open eye it seems to be the same battery, there are some technical differences between them. Let’s have a dive into their chemistry and see why are they different.

Streamlight 75175 is a nickel-cadmium battery that is used in a Streamlight Stinger Flashlight. It comes in with the flashlight itself.
Nickel-cadmium (NICAD) as we know it, was invented back in 1899. Batteries have evolved since then. But the Streamlight 75175 nickel-cadmium serves a lot of advantages. They are inexpensive to buy. Working under extreme temperatures is bliss for a NiCad battery. It charges up quickly and the process is quite simple. Even in low temperatures, it holds its charge nicely. But it can hold a very low power. And it is built from harmful chemicals.
Streamlight Battery 75375

The Streamlight 75375 is a nickel-metal hydride (NIMH) battery. It has a higher charge capacity than a Nicad battery. So it can help your device operate for a longer period. The NIMH battery technology is relatively new. It was invented in 1987. It has the built-in option of resisting an over-charge and over-discharge. And it is really lightweight making it easy to carry with you.
The problem with a 75375 is that it is expensive than a 75175. As the technology is more environmentally friendly, it costs a bit more. But it discharges at once while kept in storage rather than slowly discharging like a NiCad. Otherwise, it works fine and is more reliable.
Frequently Asked Questions
If you were to buy a new battery for your Streamlight Stinger Flashlight, it would be suggested that you go for a Streamlight 75375 rather than a 75175. Though the 75175 works in tough conditions, it will deplete its power faster than a 75375.
