Key Differences Between the 75175 and 75375

The Streamlight 75175 and 75375 share rechargeable designs but differ notably when it comes to:

1. Battery Chemistry:

75175:

• Chemistry: The 75175 utilizes Nickel Cadmium (NiCd) battery chemistry. NiCd is a type of rechargeable battery that has been used for many years.
• Characteristics: NiCd batteries are known for their ability to deliver high currents and endure a significant number of charge/discharge cycles. However, they suffer from the “memory effect,” which can decrease their effective capacity if they are not fully discharged before recharging.
• Environment Impact: NiCd batteries contain harmful heavy metals, making their disposal more environmentally problematic than other types of batteries.

75375:

• Chemistry: The 75375, on the other hand, employs Nickel Metal Hydride (NiMH) battery chemistry. NiMH is a more modern rechargeable battery technology.
• Characteristics: NiMH batteries offer higher energy density than NiCd, meaning they can store more energy for their size and weight. They also exhibit a lesser memory effect, making them more user-friendly and maintenance-free.
• Environment Impact: NiMH batteries are generally considered more environmentally friendly than NiCd, as they do not contain hazardous heavy metals.

2. Voltage:

75175:

• Voltage Output: The 75175 outputs a higher voltage of 4.8 volts.
• Device Compatibility: This higher voltage means it is suited to older Streamlight tools designed to operate on this voltage level.

75375:

• Voltage Output: The 75375 outputs a lower voltage of 3.6 volts.
• Device Compatibility: This model is matched for compatibility with newer Streamlight tools designed to operate at this lower voltage level.

3. Capacity and Runtime:

75175:

• Capacity: The 75175 has a lower capacity of 1,700 mAh.
• Runtime: This translates to a runtime of up to 8 hours, which is sufficient for basic tasks but may require more frequent recharging.

75375:

• Capacity: The 75375 has a significantly higher capacity, rated at 3,000 mAh.
• Runtime: This increased capacity provides an extended runtime of up to 36 hours, making it more suitable for prolonged use and demanding applications.

4. Recharge Time:

75175:

• Recharge Duration: A fully depleted 75175 battery recharges in 16 hours.
• Convenience: While this might be convenient for overnight charging, it could be a limitation for users who require quicker turnaround times.

75375:

• Recharge Duration: Due to its higher capacity, the 75375 requires a lengthy 48 hours to recharge from empty.
• Convenience: This longer recharge time necessitates more planning and can be less convenient for users who use their devices intensively.

5. Shelf Life:

75175:

• Storage Time: The 75175 can hold a charge for about three months in storage.
• Suitability: This shorter shelf life means it may not be the best choice for infrequent use or emergency preparedness.

75375:

• Storage Time: In contrast, the 75375 offers a significantly extended shelf life, maintaining a charge for up to 12 months.
• Suitability: This makes it a more suitable option for users who might not use the device regularly or want to ensure it’s ready for use in emergencies.

6. Compatibility:

75175:

• Device Range: The 75175 is versatile in compatibility, working with most Streamlight models.
• User Flexibility: This broad compatibility makes it a flexible choice for users with a variety of older Streamlight devices.

75375:

• Device Range: The 75375 is more selective, only functioning with certain newer 3.6V devices.
• User Flexibility: This limitation in compatibility means that it may not be suitable for users with a range of older devices, but it’s well-suited for those with newer models.

These distinctions highlight how the choice between the 75175 and the 75375 would depend on individual needs, device compatibility, and preferences for characteristics like recharge time and capacity.
