Old lights have their cells removed and get stored away in a box. Apart from that, just about everything has cells in. There are some spare cells sitting at full charge, and some more sitting at storage voltage.
.
That is new to me. What are the benefits and could you describe your method of storage ?
Thanks :+1:
I have 10 or 12 active, meaning yes they have batteries.
If i am just going to store the light, I will not have batteries in it.
Less chemical action going on when cold.
Apparently Li-ion cells can degrade when they’re kept warm.
Like most have said, stored lights are empty. Lights in EDC rotation have lithium cells in them and are ready to go at a moments notice. Extra cells are stored at room temp.
Box Queens are always empty.
Lights “at the ready” (half-dozen or so daily-use) are always loaded.
Semi-ready, another half-dozen or so stored in a small bag so I don’t lose them, are loaded but locked out. (Usually “special-purpose” lights like the GTs for snooping outside, C8F for portable oomf when a Q8/DC7 would be a bit unwieldy, etc.)
Lots of lights
Everything has a battery in it ..Locked and loaded ,ready to go.
90% of all cells are charged to 100%
maybe 40 18650's sitting at 50%
a few alkalines in lights just to keep life interesting
I have batteries in all flashlights. Every few months I check and charge them. When leaving for vacation I will allow all tails on the flashlights for safety reasons.
I have charged-up batteries in all my flashlights. I rotate an EDC at least weekly and charge it back up when I switch to my next favorite EDC. I only have 2 extra lithium ion batteries, and 1 of them is for my wife when her ZebraLight no longer stays on high. Thus she’s not out a flashlight for too long.
I have more lights that batteries. I tend to keep one or two lights per form factor ready to go, with the rest sitting empty in a display cabinet.
Yes. A few 14500 that I needed 1 of, but which came in packs of 2. A pair of 16340’s will be joining the storage pile soon as I’ve come to the conclusion I don’t favour that form factor.
All the lights that I’m not using sit on the shelves in my gun safe. None of those except for maybe two of them have batteries in them. The ones I keep in my emergency bag all have cells in them, but I keep the tailcaps loose to help mitigate drain. I’ll pull them out every couple of months to top them off. If I need a light right away, I always have one or two in my pocket so no need to keep cells in the lights I’m not using.
Yes for AA/AAA lights. No for high drain batteries like 18650s, 16340s…
Always in and charged, charged spares as well
Yes for NiMh.
No for liion. I mostly keep them in case at storage voltage until needed.
My wife was looking for a light on my shelf and was frustrated that none would turn on.
My EDC and mid ranged lights always have fully charged cells in them.
My large lights with battery carriers[ 3 or 4 cells] are Fully charged in a large pill bottle with a silica gel pack inside.Ready to go.
I’m about 50/50. I have a lot of lights that I keep batteries in because I often buy specific batteries for specific lights. I’m kind of an idiot though because I just charge them up and let them sit. When a light makes it back into regular rotation I’ll often do a refresh cycle on the batteries and a capacity test. So far despite years of neglect almost all my cells are holding up quite well.
All lights fully loaded and spare cells in a tool case, some fully charged some not.
Some lights have been sitting unused for years and when i finally think about checking them i find old cells i forgot about, like the Trustfire “flame” i used in my early days with this addiction. 
about 50/50 for me. I keep trustworthy cells in more often used lights but keep lesser used lights empty. I also try to rotate my cells throughout so one never sits long in queue with a full charge.
my rotation;
16-18650s,
2-18350s,
4-NiMh sub-C,
20+randomloops AA & AAA size,
4-14500 Li-Ion,
4-14500 LiFePo4,
s. I recently found an alkaleak puking all over the top of one of my speakers. It was next to the light I intended to use it with of course. at least it’s a scrappy-looking piece of woodwork to begin with.
and the light survived!
Haha, you might be a flashaholic if…
Cool 
I have many more flashlights than batteries. Batteries are expensive!
I keep batteries in my EDC lights, plus my “house light” (L6) and my Z1, currently. The only light that has a connected circuit is the FW3A, everything else is either locked out or has a mechanical switch.
