WARNING

Caring for the battery

Store the light at room temperature in a dry place. Avoid moisture, or extreme

hot or cold.

Store the light in the charged condition. Avoid ‘deep discharge’. Battery life will

decrease if the battery is stored in a fully discharged condition.

Over time, the run time of the battery will diminish. Expect about 500 full

charges, depending on care. After a full life, the battery will continue to charge

but with a lower run time. When the run time is unsatisfactory, do not open the

case of the light or incinerate; please recycle.

Traveling with the battery

Li-ion batteries cannot be shipped by air due to airline regulations. When

traveling by air, place the light in your carry-on.

where to do this at www.call2recycle.org
