Too long for the 3 lights I tried to use
"These batteries are too long for 2 of my Astrolux lights and a Klarus light. In the Astrolux EC06 (Sofirn Q8) the high pressure exerted when trying to get these batteries to fit causes the light to be inoperable. In the Klarus light--again--the high pressure created by threading the body to the head of the light over-compresses the spring to the point that it's a concern. This light worked with the battery installed, but the exceedingly tight fit presents problems. Also Battery Junction charges a 15% restocking fee to return over $60 worth of batteries that, in my experience, offer a poor fit at best."
GOOD BATTERY
"Very good battery at a greater price. This runs my flashlight at greater than advertised run times because of the higher power."
shuts off
"Can't handle a Fenix TK 16 flashlight on it's brightest setting. needs to be charged to reset the protection."
Q&A
- HOW LONG ARE THESE? OTHER BATTERS FROM SAMSUNG WE PURCHASED WERE TOO LONG FOR OUR LIGHTS (WE USE ABOUT 12 DAILY IN VARIOUS SHOP APPLICATIONS}. WE ORDERED 10 BATTERIES LAST TIME. 2 FIT, BUT 8 WERE LONGER AND USELESS. WE HAD NO IDEA HO9WTO ORDER THE "SHORT" ONES. NO INDICATION AT ORDERING THAT THESE CAME IN DIFFERENT LENGTHS.
- The dimensions for these batteries is on our site. They can vary slightly from battery to battery or batch to batch but these variations should not be extreme. The dimensions: Dimensions Length 2.95" / 75 ± .5 mm Diameter .82" / 21 ± .5 mm Weight 2.45oz / 69.4g
