Similar applications in which lithium cells offer an advantage include personal grooming accessories, PIR sensors, high-tech flashlights and night-vision goggles. In particular, lithium cells work well in equipment that demands occasional short bursts of high current – not least in photography flash units, where their relatively light weight is also beneficial.

New long-lasting Energizer Ultimate 1.5V AA or LR6 batteries are capable of lasting up to eight times longer than standard equivalents. Renowned for durability, the Ultimate lithium range is a top choice for devices with occasional high current demands. A common battery size, AA LR6 1.5 Volt cells are frequently used in photographic equipment, portable radios, compact flashlights and larger remote controls. Energizer Lithium Ultimate cells are a top choice for devices that require high current and reliable performance. Usefully, the battery weight of just 100 grammes is around 30 percent less than typical alkaline cells. Each cell measures 51 millimetres in length and 15 millimetres in diameter. Additionally, these Ultimate batteries are suitable replacements for sizes 4006, AM3, E91, FR6, KAA, MIGNON, MN1500, ND62S, R6 and UM3. Reliable: Each lithium double A battery boasts up to 20 years' shelf life in storage and is tolerant of extreme temperatures, from -40C to 60C, for year-round indoor and outdoor use. Each LR6/AA cylindrical cell measures 51 millimetres (height) by 15 millimetres (diameter). Ultimate AA batteries are direct replacements for size codes AM3, E91, FR6, L91, KAA, MIGNON, MN1500, ND62S, R6, UM3 and 4006.
