Be sure to follow the correct polarity (+/-) when installing batteries. Polarity is indicated in the battery compartment of your light.

Do Not Mix

Do not mix alkaline, standard (Carbon-Zinc), or rechargeable (Lithium-ion) batteries.

Same Time

 Replace all batteries in a product at the same time. Do not mix old and new batteries.

No Fire

Do not dispose of batteries in fire.


Remove batteries when consumed or if product is to be left unused for an extended period of time (>30 days). Any batteries stored in a device for prolonged periods can cause corrosion. Clean the battery contacts in your device immediately if any corrosion is observed – corrosion from prolonged battery storage is non-warrantable.


Follow proper battery recycling instructions. For alkaline batteries, recycling instructions are printed on your battery’s packaging. For Lithium-ion batteries, proper disposal includes recycling at a household hazardous waste collection point (check with your local landfill, or your retailer may offer a battery recycling drop off location). Lithium batteries may NOT be placed in the trash.)
