A: Streamlight does not support the use of batteries other than those specifically listed in the instructions. Normally the lamps and current regulators are designed for a specific type of battery, and using other batteries often results in poor performance, either low output or extremely short lamp life, depending on the battery types involved.

A: Research has shown that the “memory effect” is a rare phenomenon and is almost nonexistent in high-drain applications such as flashlights.

Some tips to help prolong the life of Ni Cd batteries:

• The light should be returned to the charger when it is not in use.
• It should never be run until the battery is completely exhausted.
• Return the flashlight to the charger when it begins to dim.

A: Nickel Metal Hydride AA replacement rechargeable batteries seem to work okay. However, since the Streamlight Jr. Luxeon was designed for alkalines and we cannot possibly test all of the aftermarket replacements, we cannot recommend the use of any batteries other than alkalines.

A: No. Routinely running the lamp until it extinguishes will drastically shorten the life of the battery.

A: No. Streamlight products are optimized and the components can be damaged or destroyed by the use of anything other than the recommended battery type. The use of improper or substandard lithium batteries can be especially dangerous.
