Here are some of the most common questions about these common-battery flashlights

Ask us anything

Which is better, an AA or AAA flashlight?

It depends on how you’ll carry and use it. AAA flashlights are smaller and lighter, which makes them ideal for pockets, purses and close-up tasks. AA flashlights hold more energy per battery, so they generally run longer or put out more light. They’re the better pick for a main household, vehicle or outdoor light.

How long do AA batteries last in a flashlight?

It depends on the brightness setting and how many batteries the light uses. On its highest mode, a light drains batteries much faster than on low, often several times faster. For the most runtime, use the lowest mode that does the job. Each product page lists runtime by mode.

Should I leave batteries in a flashlight I’m storing?

For long-term storage, no. Alkaline batteries can leak and corrode the contacts if they sit drained inside a flashlight for months. Store fresh batteries in a sealed bag next to the light, or check it every few months and replace the batteries at the first sign of dimming.

Are battery-powered flashlights better than rechargeable for power outages?

They’re often the more reliable choice. Alkaline batteries keep their charge in storage for years, and you don’t need electricity to power the light back up. A rechargeable light is only as useful as its last charge. Many households keep one of each. See our Home & Emergency Prep collection for more outage-ready lights.

Can I use lithium or rechargeable AA and AAA batteries in these flashlights?

Police Security AA and AAA flashlights are designed with standard alkaline batteries in mind. Though rechargeable AA and AAA batteries may work in the lights, we do not recommend them because the lights are not designed for use with these batteries.

You should never use lithium-ion cells like 14500 batteries in a AA flashlight.

Why Choose a Flashlight That Runs on AA or AAA Batteries?

AA and AAA batteries are the most widely sold batteries in the country. You can find them at gas stations, grocery stores and hardware stores, and probably in a drawer at home already. A battery-powered flashlight needs no charger, no cable and no outlet. When it dims, you swap in fresh batteries and it’s back to full brightness in seconds. That makes these lights a dependable choice for a glove box, a nightstand or a utility drawer, where a light may sit for months before you need it.

AA vs. AAA Flashlights: Which Size Do You Need?

AAA flashlights: smaller and lighter.

AAA cells are slimmer, so AAA lights tend to be penlights and pocket flashlights that ride easily in a shirt pocket, purse or toolbox. They suit close-up work such as reading labels, checking a breaker panel or looking under a sink.

AA flashlights: more power per battery.

An AA cell holds roughly two to three times the energy of a AAA. AA lights generally run longer or brighter at a similar size. Multi-battery designs that use six or nine cells reach the high-output, long-throw end of the range.

Battery-Powered or Rechargeable?

If you use a flashlight daily, a rechargeable flashlight saves money on batteries over time. If a light spends most of its life waiting for an emergency, or you need power with no outlet nearby, AA and AAA lights are the simpler choice. If you want both, Twin Power® lights charge over USB and also accept AAA batteries as a backup.

Battery Care Tips

Alkaline batteries can leak if they sit drained inside a light for a long time. Battery corrosion is the most common way a stored flashlight gets ruined, and our warranty doesn’t cover it since it has nothing to do with manufacturing defects. For a light you’ll store long-term, keep fresh batteries in a sealed bag beside it instead of inside it, and test it every few months.
