![]() ![]() Lithium Cobalt Oxide (ICR, LiCoO2) AA battery chemistry feature a nominal voltage of 3.6 - 3.7 V per cell, with the maximum, recommended charging voltage of 4.2 V. Lithium Iron Phosphate (IFR, LiFePO4) AA battery chemistry feature a nominal voltage of 3.2 - 3.3 V per cell, with the maximum, recommended charging voltage of 3.5 - 3.6 V. Lithium Manganese Nickel (INR, LiNiMnCoO2) AA battery chemistry is very similar to IMR AA battery chemistry and they both can provide strong currents, with slightly lower capacity. IMR AA batteries commonly have a smaller capacity but are capable of delivering stronger currents. Lithium Manganese Oxide (IMR, LiMn204) AA battery chemistry feature a nominal voltage of 3.6 - 3.7 V per cell, with a maximum, recommended charging voltage of 4.2 V. Lithium-Ion AA batteries are based on one of the lithium-ion rechargeable chemistries, including: Lithium-Ion AA Batteries - 14500 Batteries ![]() One of the most popular Li-FeS 2 AA batteries is the Energizer Li-FeS 2 AA battery (Datasheet, PDF, link opens in the new window), which practically sets the standards for other Li-FeS 2 AA batteries. That is why Li-FeS 2 AA batteries are the preferred choice for high drain, but also for standby applications like cameras, flashlights, security systems, medical devices, etc. ![]() Other benefits of Li-FeS 2 AA chemistry include extra-long shelf life (up to 20 years!), stable capacity regardless of the discharge current (at least up to 600-800 mA current), supports of the high drain devices, etc. Lithium Iron Disulfide (Li-FeS 2) AA batteries are non-rechargeable batteries, featuring a nominal voltage of 1.5 volts and a typical capacity of 2700-3300 mAh, with some models having capacity up to 3500-3600 mAh.Īlthough their Open Circuit Voltage (OCV) is 1.8 volts, as soon as the load is applied, the voltage of the Li-FeS2 AA batteries drops down to 1.5 volts, making them compatible with older Zinc-Carbon and Alkaline AA batteries. Lithium Iron Disulfide (Li-FeS 2) AA Batteries Lithium AA batteries may feature several different chemistries, including: The following comparison chart lists some of the most popular AA battery chemistries, with their most important features and specifications. Lithium batteries that commonly feature 3.0+ volts, should NOT be used instead of 1.5V AA batteries unless explicitly allowed by the device manufacturer. Lithium AA batteries feature physical dimensions of 14.5 mm (0.57 inches) in diameter and 50.5 mm (1.99 inches) in length - just like any other AA battery.įor many years, the typical AA battery voltage was 1.5 volts with many devices still accepting only 1.5V AA batteries. Lithium AA Batteries - Dimensions, Chemistries, and Features ![]() Lithium is a lightweight, rather reactive metal, and its chemistries are commonly used in batteries providing different features including voltage, capacity, shelf-life, drain current, and similar.Ī typical AA battery is a 1.5 volts battery and with all the lithium chemistries in use, getting "the right one" may be a somewhat difficult task.
