Duracell N LR1 alkaline batteries 1.5 V pack of 2

The LR1 battery is a 1.5V alkaline battery in a cylindrical format. This is a size you’ll find in a wide variety of devices — proximity alarms, portable GPS trackers, small decorative clocks, garage door openers, door unlocking systems, compact flashlights, and some older cameras. I consider this type of battery an essential for equipping everyday accessories and devices that require discreet, reliable power.

Technical specifications of the LR1 battery

The Duracell MN9100 LR1 battery is a standard cylindrical alkaline battery. Nominal voltage: 1.5V. This size is also known as N or MN9100, depending on the region and manufacturer. As a leading battery brand, Duracell offers proven technology: alkaline, mercury-free, with stable voltage throughout its service life. Its compact cylindrical format makes it compatible with a wide range of small portable devices. I find that Duracell maintains consistent quality across its range, although actual battery life depends greatly on the device being powered and its power consumption.

Common uses and compatibility

You can use this LR1 battery in:

• Proximity alarms and alert systems
• Portable GPS trackers and beacons
• Decorative clocks and wall clocks
• Garage door openers and remote controls
• Door unlocking systems
• Compact flashlights
• Some older digital cameras

Before buying, make sure your device actually requires an LR1 battery (or MN9100, or N — designations vary by manufacturer). Check the device label or user manual. Between us, it’s easy to choose the wrong size if you buy blindly — take 30 seconds to confirm the reference.

Storage and service life

Like any alkaline battery, the LR1 can be stored for a long time in a dry place at room temperature. Duracell generally states that it can be stored for several years. Once installed in a device, its service life depends on the device’s energy consumption — a quiet alarm may last 12–18 months, while a flashlight used regularly will drain it more quickly. My advice: buy it when you need it rather than building up a huge stock — alkaline batteries slowly lose charge even when unused.

Who it’s for and who it isn’t for

Who it’s for: Anyone who needs to power a small portable device (alarm, tracker, clock, remote control) with a standard LR1 battery. If you’re looking for a reliable, recognizable brand, Duracell is a solid choice.

Who it isn’t for: If you need a different battery size (AAA, AA, 9V, etc.), this LR1 won’t be useful to you. Browse our selection of batteries and power cells to find the size that matches your device. If you’re looking for a rechargeable solution for intensive use, rechargeable NiMH batteries are more economical in the long term.

A friend’s advice — Always keep a few LR1 batteries in a drawer if you have devices that use them. There’s nothing worse than discovering that your battery is dead just when you need it. Duracell is a safe bet.
