Energizer 3LR12 4.5 V Max Battery

Product Information

Commonly used on computer motherboards as nonvolatile BIOS memory and real-time clock (RTC) backup batteries, device remote controls, remote key fobs for cars and other vehicles. Typical 20th century uses for this high capacity dry cell named for its 6-inch height include school science experiments, and starting glow plug model engines and in antique equipment. Used in Skytronic PRO Audible Altimeter but also flow meters and organizers (as a memory backup battery). The Headway 38120HP cells are used in high discharge environments as they have very good continuous/peak discharge rates (10C/25C). Can be replaced with an AA cell using a plastic sabot (size adaptor), with proportional loss of capacity.

This non-standard size battery is designed for reliability in specialist applications such as lighting. Most sizes are uncommon today; however, the PP3 size (and to a lesser extent PP8, used in electric fencing, and PP9) is readily available.It is also frequently referred to as a lantern battery, with it mainly being used in specialist flashlights and lanterns. A rechargeable lithium-ion version is available in the same size and is interchangeable in some uses. It was used in some early transistor radio amplifiers with a Class B output stage, allowing the loud speaker to be connected between the amplifier output and the battery center tap. Concept introduced by Tesla in 2020 as a high energy capacity cell for use in EVs, [234] [235] and entered production by 2023. Still popular for school science class use as a variable voltage supply as the current version has several taps at 1.

LiFePO4 properties: long lasting (2000+ cycles), safer, more stable, good continuous/peak discharge rates (3C/10C), less energy dense. Used in locations susceptible to high vibration/shock where connectors may be knocked off the terminals. Miniature zinc-air batteries are button cells that use oxygen in air as a reactant and have very high capacity for their size.Cells less than one centimeter in height are assigned four-digit numbers, where the first two digits are the diameter in millimeters, while the last two digits are the height in tenths of millimeters. A rare battery, sometimes used in car security (car alarm/keyfob batteries), organizer (backup battery for PDA such as Psion etc. Can be replaced with an AA cell or a C cell using a plastic sabot (size adaptor), with proportional loss of capacity. This RS Pro alkaline battery is made with durable materials and the ability for a long shelf life completed with positive and negative spring terminal tags.
