Why use L91/L92 lithium primaries?

Me, same.

Wise for any area susceptible to the occasional earthquake/hurricane/tornado/swarm’o’locusts, I’d think.

Once the dust starts to clear and the fires are out and the sun comes up, there’ll be time to set up recharging stations for the neighbors.

But for that first few hours — I’ll be glad to be handing out flashlights with Energizer lithium primaries.

Heck, during the first few hours of dusty, shaky and dark, people will drain cells dead and throw them away without looking at them. And that’s fine.

And if it’s daytime — you’ll be glad if you remember having studied this, before you needed to know it:

I still use L91/92’s in devices that might sit a few years without use. I use Eneloops’ also but for items that get a bit more use. I am budget but not on batteries.

Lithium primaries are MUCH ligher weight than Eneloops. The difference is definitely noticeable in the pocket. If weight is an issue, such as for a small EDC, the energizer lithiums work great. Why carry around extra weight when you don’t have to?

I use eneloop pro clones, Duracell, amazon pro, imedion etc. But I also keep a stash of about 400 alkaline cells 200 aa 200aaa and best buy has clearance sales every few months on there energizer advanced lithium for like 3.99 a 4 pack or something. And on amazon every two months I have them send me a pack of 8 aa ultimate lithium’s. Just want to he prepared. I have 10 years to use the alkalines and I will in time with two daughters. But I live in the heart of hurricane alley. Power can be out for up to two weeks. Can always charge batteries in the car. But usually using the car to run power inverters for fans and keep the refrigerator going every couple hours. Car batteries have amazed me. Long as you start it up every few hours for about 20 mins you’d be surprised what you can run off it. I’ve ran a swimming pool pump for a 16 ft round pool for about 12 hours without starting. Crabked right up. But back to subject. Don’t wanna get caught unprepared. Need my lights and lanterns to work. Aa and lithium lights. Along with gadgets to keep my oldest daughter entertained. All three chemistries would get heavily used.
And might be soon. That storm out by Cuba is predicted to come right in the mouth of the Mississippi just like Katrina did. Well Katrina was 30 miles closer to me. If this storm does this and develops I’ll be homeless again. Like I was after Katrina. But that’s s whole different story

I would like to learn more about that using of the car battery to cycle the refrigerator periodically, that has been my plan for years but I keep waiting for the money for a quality inverter.

A solar car battery charger could help keep your car battery healthy during those uses.

Do you think this inverter would be enough for a modern top freezer fridge?

They’re good for your average person who’s not going to remember to charge their batteries. I threw some in a lantern and a cheap low output single mode 2aa energizer light for my mom in case of emergencies

And for a buk each, getting CR123As is a good choice, too.

Can run in 1-cell lights (Jet-II, i332, KL03, etc.) or 2 at a time in 18650 lights that can stand up to 6V (most Nitecores and a bunch of Sofirns).

You’ll notice the number of emergencies rises with age, like to reading small print in the evening.
So I have a lot of AAA lights scattered around the house. Most of them with L92 primaries.
For the moments I want just some light, any light, at THAT particular moment.

The batteries in my 18650 lights are never “suddenly empty” so it’s LiIon for those.
They are just too bulky to stash everywhere. I’ll take them if I know I’ll be needing a light (for a walk).

> Why use L91/L92 lithium primaries?

There is no reason for me to use disposable Lithium Primaries.

I use Eneloops, because I like saving $$$

example:
today on ebay I can buy:
4x L92 for $8 = $2 each

I save $2 every time I recharge an Eneloop.

I have a camera that absolutely refuses to play nice with NiMh 1.2v cells for more than 10 shots. Lithium primaries are a reasonable & safer alternative to alkaleaks. Once the camera rejects them, they can be used in other AA lights for a long time.

Lately, I've been running 1.5v Tenavolt rechargeable LiIon cells in it with very good results. Tried them based on info gleaned mostly here on BLF. Too soon to establish time/shots before need to be recharged, but results so far are very promising.

Tenavolt should work OK for devices demanding the 1.5v. They don’t work well if there is a constant requirement for > 2.0A, like lots of flash use. They do OK up to 1.5A.
Good battery after almost 2 years of use for me. Going for the long term test.

No, you don’t. No matter “how little,” what do you suppose is the cost in electricity for your recharge? Each, and every time, even? If your going to be priggish, at least be factually priggish.

Charging an AA Eneloop costs, what, one penny? Even long term the cost of the charger probably affects the equation more.

In some situations we don’t have access to a source of electricity to make a charge… so we have no choice but to turn to the primaries.

Energizer Lithium are the best non rechargeable AAA and AA batteries. Great for thermostats. They last for 3 years straight.

I use Eneloops as well, for more mundane things like portable radios, cameras and wall clocks - but for EDC use like my flashlights, I really appreciate the light weight and long life of my Energizer Ultimates. I’ve had too many of my favourite things ruined by alkies to ever use another one. (I do keep a few around in case of ‘borrowers’ - they get a plastic 2AA with alkies that I write off the moment it leaves my hands.)

If you watch for sales and bulk-buy prices, the added expense of the Energizer Ultimates is not that big of a sacrifice. Skip a single restaurant lunch, and you’ll have the price of a couple of years worth of lithium primaries.

I find L91/L92 to work VERY well in glove box lights if you aren’t going with CR123. For me, if I have room for a 4xAA or 6xAA I’ve rather go that route than CR123 just to make gas station replacement easier, if needed.

Keep an eye out for the L92’s on sale.

Please post if you see a good sale of fresh-dated Energizer Lithium cells. Last batchI bought must have been on some wholesaler’s stock shelf for ten years or more, going by the year timestamp on them.

Long shelf life shouldn’t mean “never too stale for retail sale” – ya hear me Amazon?

Hank: Since the (almost) conclusion of the pandemic, the price of these have gone up considerably. The best price I have seen on them are at Sam’s Club. They come out at $1.97 each in 18 packs for each AA and AAA. Ya, you gotta be a member, but as I have said before, ask your friends and neighbors if they are members…or if my memory serves me correctly, last year around Christmas time, they offered a $6.00 membership for a year…who knows, they might have something else for you to purchase.

I keep them around for my blink security cameras (they don’t like NiMH)… Also thought they’d be good for potential power outages, but I’m pretty sure at this point, I only own 2-3 AA flashlights, and at $2+ a piece, it’s cheaper to keep cr123s around
