I ordered a spare Klarus dual polarity 18650 battery with my Klarus RS20 flashlight and had some questions.
First, though most 18650 batteries claim to have a 500-cycle lifespan, the Klarus batteries claim a lifespan of 300 cycles. Why is this? Also, if I were to charge the Klarus batteries externally, say, in a Nitecore charger, can that be done? Seems like the contacts of both polarities would contact the charger's contacts (with positively "negative" results).
The battery I'm using is a 3600mAh type.
Can anyone help me out on this?
