I want to keep a light in the jeep. Is it too risky to keep a light with summer heat?
Lithium primary is the only way to go with this unless you want to be rotating batteries and lights based on the ambient temperature.
In more mild weather I'd say lithium ion would be fine, granted it's not in direct sunlight.
However, by far, the easiest solution here is to utilize a light with lithium primaries, store it and forget about it. It will handle all the temperature fluctuations of being inside a car long term.
Ok thx for feedback, hopefully the lights I want to dedicate to the jeep will allow to unscrew a bit to prevent that from happening18650 is fine except for a light with an electronic switch. The parasitic drain will slowly use up a wee bit of charge over time and your run time may be compromised some when you need all the runtime possible.
A mechanical switch or a light with a lockout feature would be the way to go there.
Thanks all, all I have are 18650 lights, do they make lithium primary in 18650?
And yes, I learned the hard way that Duracell/Energizer batts just rott away and spill batt acid from the heat.
I've always thought theft was a greater risk to car flashlights, so my least-expensive Surefire: SF G2Z w/ Malkoff M61N.
1x17650 in the (mild) PNW winters, rotating to 2xCR123's in the hot summers.
As it gets the majority of use in the winter, the CR123's are probably going to expire due to age rather than use.
I say stay away from alkalines, and keep the light out of direct sunlight, but otherwise, I don't think it matters much which chemistry you use to power the light.I want to keep a light in the jeep. Is it too risky to keep a light with summer heat?
