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 also lasts significantly longer than the standard batteries supplied.
