My LightStar flashlight no longer works because the batteries have leaked.

A flashlight that is damaged by battery leakage or corrosion is a condition beyond our control, as alkaline batteries inherently leak, especially due to extreme changes in temperature and humidity.  As LightStar does not manufacture alkaline batteries, they cannot be covered by warranty, outside of immediate new-package use (new/fresh out of LightStar packaging).  Please review details on the Warranty page or Warranty Policy for more information.

It may be possible to clean your battery terminals, if the corrosion was not too bad.  –  Clean/wipe/shake any excess corrosion away and use the eraser-end of a pencil to scrub clean the contacts.  (Be sure to wipe clean after with dry cloth to ensure all corrosion has been removed.)  Then, slightly wet the end of the terminal or battery (e.g., tongue) to create a new connection.


What options do I have if the batteries I have recently purchased have leaked and/or exploded in my flashlight causing damage?

  • Keep the batteries and if possible the receipt / original package of the batteries you purchased. This information can help you when you send your battery damaged product to the battery manufacturer.  This document is not all encompassing, however it gives you the route and some contact information you can use to contact the battery manufacturer.

Battery Warranties:

Battery leakage is the #1 cause of failure in alkaline-powered flashlights. While LightStar Corp. does not warrant against battery leakage in its alkaline battery products, the Battery Manufacturers often accept responsibility for damage to products caused by their branded leaking batteries. We suggest that before returning any alkaline lights to LightStar Corp. for repair, you first try to determine if battery leakage is present. If the battery cap cannot be removed (because of corrosion), or if after removal it is found that there are swollen batteries that cannot be removed from the barrel, or the springs or contacts appear corroded, you (the customer) should use the information presented here to contact the battery manufacturers directly for remediation. You should be able to find additional customer service information on the Internet, however, we’ve provided a few listings below for your convenience:

My LightStar flashlight quit working. I have replaced the batteries with new ones and it still does not work. What do I need to do to take advantage of the limited lifetime warranty?

  • Before you send your LightStar flashlight in for warranty processing, try the switch test first:
  1.  Remove the back tail cap switch; Install fresh batteries into the barrel.
  2.  With a paper clip simultaneously touch the exposed metal rim of the flashlight and the center of the battery.

My TT-5 is stuck on strobe mode (or appears to “flicker”) how do I send it in for warranty?

  • Before you contact LightStar Corp. for service on your TT-1, TT-4, or TT-5 Tactical series flashlight please try the following:
  1. As listed in the specifications (Item #14), the TT-5 blinks-flashes (strobes) as a Low battery Indicator when the battery is almost depleted. To correct this, simply:
  • Remove your rechargeable battery from the flashlight, and perform a complete charging operation to ensure the battery is fully charged.
  • Install the fully charged battery and test the flashlight by cycling through the modes. There are three modes (High, Medium, and Low) and one strobe mode.

2.  Please see the additional information provided below to fully test the flashlight operation:

  • To activate constant on, press the power switch so that it clicks. To turn it off press the power switch fully so that it clicks.
  • To cycle through the modes, press the power switch to the on position. Then press the mode switch and release immediately; the brightness mode can be selected from:

 High, Medium, Low.

 Strobe Mode:

  • Press the power button to the off position. For instant access to strobe mode press the mode switch.
  • Press the power button to the on position.  Press the mode switch for more than 0.6 of a second to activate strobe mode. Release the mode switch within 2 seconds to return to the previously selected brightness mode.
  • Select the power on position. Holding the mode switch for more than 2 seconds will lock the strobe mode. Pressing the strobe mode switch again will stop strobe mode, and return to the previously selected brightness mode.
