Energizer Ultimate Lithium Battery L92 AAA 1.5V (blister pack of 4) - L92ULTIMATEB4

The Energizer Ultimate Lithium L92 (size AAA / Micro) is regarded as the world’s longest-lasting AA battery in high-tech devices. It was developed to far outperform conventional alkaline batteries in power-intensive applications. Thanks to its advanced lithium iron sulphide chemistry (LiFeS2), it not only offers up to 11 times longer runtimes in digital cameras, but also works under extreme weather conditions in which normal batteries would fail. The pack of 4 is the ideal stock-up size for photographers, outdoor enthusiasts and smart home owners.

Highlights at a glance

• The world’s longest-lasting AAA battery: Offers maximum power for energy-hungry high-tech devices and lasts up to 11x longer in digital cameras than standard alkaline batteries.
• 20-year shelf life: The battery loses hardly any energy during storage and is guaranteed to be ready for use for 20 years – perfect as an emergency supply.
• Extreme temperature range: Works reliably from icy -40 °C to hot +60 °C, making it the first choice for outdoor sensors in winter.
• Ultra-lightweight design: Weighs around 33 % less than a comparable alkaline battery, which noticeably reduces the carrying weight of portable devices (headlamps, GPS).
• Leak-proof: The design is engineered to prevent leakage and therefore damage to expensive electronics.
• 1.5 volt system: Is a direct "drop-in" replacement for any normal 1.5V AAA alkaline battery, but with the superior power of lithium.

Perfect for smart home & outdoor use

The Energizer L92 is the insider tip for all smart home devices used outdoors. It is ideal for Netatmo weather stations (outdoor modules), Blink Outdoor cameras or electronic door locks (Nuki, Danalock), which are exposed to cold in winter. Normal batteries weaken at sub-zero temperatures – the Energizer Lithium keeps going. Also for gaming controllers, handheld GPS (Garmin) and LED torches it is the best choice for maximum runtime.

FAQs on the Energizer Ultimate Lithium L92

Can I recharge this battery?

Under no circumstances! This is the most important safety note. The Energizer Ultimate Lithium is a primary battery (single-use). If you try to recharge it in a charger, it can explode or catch fire. For rechargeable batteries, please use NiMH rechargeable batteries (e.g. Energizer Recharge).

Why does the battery initially have over 1.7 volts?

If you measure a brand-new L92, the multimeter often shows 1.7 to 1.8 volts (open-circuit voltage). This is normal and absolutely harmless for 99 % of all 1.5V devices. Under load, the voltage quickly settles at a very stable level of approx. 1.5 volts, which it then maintains much longer than an alkaline battery (which quickly drops to 1.2 V).

May I mix lithium and alkaline batteries?

No. Never mix old and new batteries and never different chemistries (alkaline with lithium) in one device. The stronger lithium battery would "overrun" the weaker alkaline battery, which can lead to overheating, leakage or defects. Always replace the complete set.

Is the high price worth it for a TV remote control?

Honestly: No. For devices with extremely low power consumption (such as a TV remote control or a simple wall clock), a standard alkaline battery is more economical. The advantages of lithium technology (high-current capability, cold resistance) do not come into play there. Use the L92 for devices that need a lot of power or are mounted outdoors.
