At temperatures below 0 °C, this becomes sluggish or freezes, internal resistance rises, and the battery provides no power (even when full). Energizer Lithium uses a different chemistry that remains liquid and effective even at -40 °C. It is therefore indispensable for winter weather stations.Can I put them in my DECT phones?Caution: No! Most cordless landline phones (DECT) use rechargeable batteries (NiMH AAA). If you insert this lithium battery and put the phone on the charging cradle, the base station will try to charge the battery. This can cause overheating and destruction of the battery or the phone. Always check the label of the old cells ("Rechargeable" vs. "Lithium").Why is the battery so light?Lithium is the lightest metal on earth. Compared to the heavy zinc and manganese dioxide components in an alkaline battery, the lithium construction saves about a third of the weight. In a computer mouse, this changes the centre of gravity and improves handling; in a headlamp, it reduces bouncing when running.How do I dispose of the empty battery?Because lithium is highly reactive, you should cover the terminals (+ and -) of empty batteries with a small strip of tape or insulating tape. Then put them into the green battery collection boxes in supermarkets or at recycling centres. Do not throw them in the household waste!

This is the most important safety notice. The Energizer Ultimate Lithium is a primary battery (single use). If you try to charge this in a charger, it can explode or catch fire. For rechargeable batteries, please use NiMH batteries (e.g. Energizer Recharge).Why does the battery initially have over 1.7 volts?When you measure a brand new L92, the multimeter often shows 1.7 to 1.8 volts (open circuit voltage). This is normal and is 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 holds much longer than an alkaline battery (which quickly drops to 1.2 V).Can I mix lithium and alkaline batteries?No. Never mix old and new batteries and never mix different chemistries (alkaline with lithium) in one device. The more powerful lithium battery would "overrun" the weaker alkaline battery, which may result in overheating, leakage or defects. Always replace the complete set.Is the high price worth it for a TV remote?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 capacity, cold resistance) do not play a role there. Use the L92 for devices that require significant power or are located outdoors.

As a Energizer lithium can be used in high-tech devices up to 11x longer than a standard alkaline battery, you will need to buy new batteries much less often. If you calculate the costs per picture (for cameras) or per hour of operation, the lithium battery is often even cheaper - and you save yourself the trouble of constantly changing batteries.Can I use them in an LED torch?Yes, absolutely. It is actually highly recommended. Firstly, the torch is lighter and secondly, the brightness remains more constant over the life of the battery (flatter discharge curve). In addition, the torch continues to run even when it is left in a cold car in winter (-20 °C), whereas an alkaline battery often fails in such conditions.Is it dangerous?No, it is very safe when used properly. It has integrated safety valves (PTC) that interrupt the current flow in the event of a short circuit to prevent overheating. However, as with all lithium batteries: Do not dispose of in fire, do not open and do not recharge.Does it fit in the Apple Magic Mouse?Yes, the older generation of the Apple Magic Mouse (which still requires batteries) uses 2x AA batteries. The Energizer L91 is perfect for this, as it makes the mouse lighter, which reduces gliding resistance and is easier on the wrist.

It must never be placed in a charger (danger of explosion!). If you are looking for rechargeable batteries, choose NiMH (nickel-metal hydride) batteries.Why does my meter show 1.8 volts?Fresh Energizer lithium batteries have a very high open circuit voltage of approx. 1.7 to 1.8 volts. This is normal and intended. Almost all 1.5V devices tolerate this voltage without problems, as it drops quickly to a stable 1.5V - 1.6V under load. Only with extremely sensitive, old bulb torches (without regulation) could the bulb burn out, but this is very rare.Is it better than a rechargeable battery (Eneloop)?That depends.Advantage Lithium L91: Higher voltage (1.5V vs 1.2V), no self-discharge (20 years shelf life), lighter, cold-resistant (-40°C). Better for: Emergency, smoke detectors, outdoor sensors, rarely used devices.Advantage rechargeable battery (NiMH): Reusable, more cost-effective for frequent use. Better for: Toys that are played with every day.Why do I need them for my Blink camera?Cameras like “Blink” communicate via Wi-Fi and record video. This generates high current peaks (pulses). During these peaks, the voltage of alkaline batteries collapses (especially in cold), which the camera interprets as “battery empty”, even though energy is still available. The L91 supplies high current stably right to the end.
