Battery Operated Lanterns

What makes a battery operated lantern its own thing

A battery operated lantern is an LED lantern that runs on disposable cells you swap out, usually D, AA or AAA. No cable, no charging schedule. If the batteries are fresh, it works. If they're not, any gas station fixes it.

That's the whole reason to pick one over a rechargeable. A battery powered lantern doesn't care whether there was an outlet at camp last weekend. It waits in the closet until the storm knocks the power out, and then it does its job.

The shared basics of lanterns (lumens by space, hanging, LED vs gas) are on the camping lantern page. This page sticks to what's different when the power comes from a pack of batteries.

The table on this page lists lanterns whose maker or listing says they run on standard AA, AAA or D batteries, longest runtime first. Its columns cover brightness, runtime, which cells it takes, water rating, shape, modes, hook, weight and pack count, from the maker first and the Amazon listing where the maker is silent (marked as listing values; weight is the maker's alone). The water rating appears only when the maker states it. A dash means neither states it; we don't fill it in.

What to look at in a battery lantern

These are the specs that separate a good closet lantern from a dud, roughly by importance.

The cell size sets the weight and the runtime

The Power column shows which cells a lantern takes. That one value decides a lot.

Energizer's own datasheets give the weights of its alkaline cells:

• D cell: 139 grams, about 4.9 oz each
• AA cell: 23 grams, about 0.8 oz each
• AAA cell: 11.5 grams, about 0.4 oz each

A D cell weighs about six AA cells, so a D lantern trades weight for a much bigger battery. An AA lantern is the middle ground and shares cells with most headlamps and trail gear. AAA lanterns are small and light but carry less. A lantern that takes several D cells is a car-camping lantern, not one for a two-mile walk to a blind. (Renee once asked why my "small" lantern was the heaviest thing in the beach bag. It was the batteries. It's always the batteries.)

Runtime grows when you turn it down

The Max runtime column is the longest the maker or the listing states. Under the ANSI FL1 standard, runtime is clocked until output drops to 10% of where it began, and that longest number almost always comes from the dimmest setting.

There's a battery reason too. Energizer's alkaline FAQ says a battery is much more efficient at lower drain, and the capacity you actually get falls as the drain rises. So a lantern on high doesn't just use the batteries faster. It also gets less total energy out of them. If you want a battery lantern to last a long weekend, plan on running it a notch or two down.

Alkaline, lithium or what the manual says

Most battery lanterns ship with alkaline cells in mind. Lithium AA cells are the upgrade for cold camps. Energizer's sell sheet for its lithium AA lists an operating range of -40°F to 140°F, and says the cell is up to 33% lighter than alkaline. Its alkaline AA datasheet lists 0°F to 130°F.

Before you swap chemistries, read the lantern's manual. It lists the battery types the maker allows, and that's the one to follow.

Don't try to recharge regular alkaline cells. Energizer's FAQ says only batteries labeled rechargeable can be safely recharged, and charging others greatly raises the chance of leaks and rupture.

Cold weather slows alkaline cells down

This is the spec that matters in November. Energizer explains that alkaline cells use a water-based electrolyte. As the battery nears 32°F, the chemistry slows down and runtime drops. The good news: the lost runtime comes back as the cells warm up toward room temperature.

In practice that means a battery lantern sitting on a frosty table at dawn may look dim, then perk up inside a warm cabin. Keep a spare set of cells in an inside pocket and swap if the light sags. Or pick lithium cells for the deer camp lantern, if the manual allows them.

Water rating and hook

Battery lanterns use the same IPX water ratings as other lights. IPX4 means splashes from any direction don't harm it; IPX7 means it survives temporary immersion in about 1 meter of water, per Streamlight's summary of the FL1 standard. A battery lantern that rides in a truck bed or a boat wants the higher number. Check the battery door seal while you're at it, since it's the weak point on any battery light.

The hook column matters more than people think. A battery lantern hung from a canopy or a tent loop lights the table instead of your chin.

Hybrid lanterns: battery backup built in

Some lanterns take both a rechargeable battery and disposable cells. One maker's instructions describe it plainly: the lantern runs on its rechargeable battery first, then switches to the AA cells if they're installed. Another maker's manual for a rechargeable lantern says to replace the alkaline batteries when the light shuts off, so the same idea shows up in more than one lineup.

A hybrid makes sense if you like charging over USB but want a fallback. If the table's Power column says hybrid, it counts as a battery lantern here too.

Battery lantern vs rechargeable lantern

This is the real decision for most people, so here it is side by side.

• Getting power: a battery lantern takes cells from any store; a rechargeable needs an outlet, a car port or a power bank
• Sitting unused: sealed alkaline cells carry a long shelf-life rating; a charged built-in battery slowly loses charge
• Cold mornings: alkaline cells slow near freezing, lithium AA cells are rated far colder
• Weight: D cells are heavy; AA and AAA lanterns are closer to a rechargeable
• Ongoing cost: you keep buying cells for a battery lantern, while a rechargeable just needs the cable
• Charging other gear: some rechargeables double as a power bank; a plain battery lantern doesn't

Neither one wins everywhere. The battery lantern wins anywhere the outlet is a question mark. The rechargeable wins on the trips where there's always a charger in the truck, which is why most camps end up with one of each. (That's not an excuse to buy two lanterns. It's a reason. I've explained the difference to Renee more than once.)

Who a battery operated lantern is for

The power-outage bin

A battery lantern is the one I'd put in a home emergency bin. Energizer's datasheets list a 10-year shelf life at 70°F for its AA, AAA and D alkaline cells. A sealed pack of batteries in the bin and an empty lantern beside it is ready for a long time.

Here's my one opinion on this page: the lantern that lives in a bin, a closet or the truck should run on disposable batteries. The reason is in the manuals. One rechargeable lantern maker writes that fully charged batteries lose charge over time if left unused. A sealed pack of alkaline cells is rated to hold for years. For a light you'll forget about until you need it, that difference decides it.

Deer camp and the truck

At Hemlock Run the battery lantern lives behind the truck seat, with the batteries in a zip bag beside it. When the cabin generator coughs, it's the first light on. Walt calls it "the one that works," which is the nicest thing he's ever said about anything I packed.

Kids' tents and the outhouse path

No charging cable to lose, nothing hot to touch. A small AA or AAA lantern is an easy one to hand to a kid for the tent, as long as somebody else holds the spare batteries.

Battery care: leaks, storage and swaps

Battery lanterns have one real enemy, and it's a leaking cell. Energizer's FAQ says alkaline batteries typically don't leak under normal storage and use. It lists what raises the risk:

• Mixing chemistries, or fresh cells with used ones
• Deep discharge: leaving dead cells in the lantern
• Heat: long exposure to high temperature
• Charging cells that aren't rechargeable
• Physical damage to the cell

One lantern maker's manual adds its own short list: don't mix old and new or different types, replace all the batteries at the same time, replace dead ones right away, clean the contacts before installing, and remove the batteries if the lantern won't be used for a long stretch.

Energizer says alkaline leakage is caustic. If it gets on your skin, flush the area with plenty of water for 15 minutes. Don't keep loose batteries in a pocket with keys or coins either; Energizer warns that a short circuit can make a battery very hot.

For storage, Energizer recommends room temperature, 68°F to 78°F, with moderate humidity. It says the refrigerator or freezer isn't needed and can harm batteries through condensation. So the truck in August is the worst place for spares, and the fridge is not the fix. (I know a cabin fridge door with spare batteries next to the ketchup. Not naming names.)

To check whether old cells are still good, Energizer suggests a battery tester that puts a load on the battery. A plain voltmeter without a load can be misleading.

How to set one up for camp

1. Buy the cells the lantern's manual lists, all from the same pack.
2. Write the install date on a piece of masking tape inside the battery door.
3. Run it once at home on each mode, so you know which one you'll use at camp.
4. Pack one full spare set, in a zip bag, away from keys and coins.
5. After the trip, take the batteries out if it's going back in the closet.

Battery lantern safety is short. Install cells the right way round, never mix old and new, and keep spare batteries where kids can't reach them.

Who should skip a battery operated lantern

If you camp every weekend and there's always a charger in the truck, a rechargeable lantern will cost you fewer trips to the store. If you hike far and count ounces, the cells in a D lantern are dead weight; look at small AAA lights or a tent light instead. And if all you need is light to walk, the headlamps page has a better answer.

For everyone else, a battery lantern is the light that's there when the power isn't. Keep the spare batteries in the bag, not in the museum.
