How Many mAh Is a Lithium AA Battery?

Lithium AA Battery is a battery proven to be the best battery of today and the top choice for flashlights and headlamps. It also has several features such as no memory effect, a better self-discharge rate, and a wide operating temperature range. It does not have chemical substances that cause deterioration or leakage when they are left unused for a long time. It also has a long storage life and can be stored for 5 years without losing its maximum capacity.

How Many mAh Is a Lithium AA Battery?

Lithium Batteries are all about capacity. They are rated by how many mAh (milliamps per hour) they put out. This specifies how long they last on a charge. The higher the number, the longer it runs; that's all there is to it. To determine how many hours one mAh of power will last, divide 60 by the milliamps (mA). For example, if you have a flashlight with 200 mA batteries in it running for an hour, it would need 100mAh.

Hobbyists are often interested in high-capacity lithium AA Batteries. Hobbyists enjoy these batteries because they are lightweight and have excellent capacity performance at moderate prices. They are significantly lighter than alkaline cells and can provide three times more capacity or about 8X greater milliamp hours per dollar compared to alkaline cells! High-capacity Lithium AA cells can deliver up to 2850 mAh and more, such as the Energizer L91 Lithium cell or Lithium-Ion rechargeable batteries.

Conventional alkaline batteries have a nominal voltage of 1.5 Vdc; however, their linear discharge curve starts at around 1.6 volts and ends around 0.9 volts under load - which is below acceptable levels for most electronic devices. As a result, additional circuit elements are required to maintain the voltage needed by the device running off an Alkaline battery pack at its designed level, leaving little leftover for actual use by your device's built-in electronics.

How Do You Extend A Lithium AA Battery Cycle Life?

Lithium Batteries have the longest cycle life of any rechargeable battery technology currently available. A new, unused AA cell will have a typical capacity between 1600mAh for a regular quality cell and 2850mAh+ for a high-performance Lithium-Ion cell with up to 70% additional capacity compared to an equivalent new Alkaline.

Unused batteries can be left in their packs either partially or fully charged for extended periods without going dead. PowerStream Technologies guarantees its batteries will keep 85% of their capacity up to 5 years, which is best in class - especially considering how expensive these cells are. Other factors like heat, cold, and humidity do not materially affect Lithium-Ion batteries.

Lithium batteries are not subject to the "memory effect" that NiCd and NiMH batteries suffer from and do not need to be fully discharged before recharging them to extend their life. Proper conditioning of lithium cells is done by applying a moderate discharge load for about 5 minutes and then charging them until they reach full capacity. When charged this way, Lithium Batteries will last significantly longer than when plain charged or when conditioned regularly.

Partial discharges can contribute to the cycle-life loss, especially with nickel-based chemistries with much lower specific energy than lithium chemistry, so try to avoid applications where you only draw power out of your battery pack in small increments as portable flashlight applications, for instance.

Conclusion

Lithium Batteries offer significantly higher capacity (mAh) than alkaline cells and can provide up to three times greater milliamp hours per dollar required by high-drain devices. They also have the longest cycle of any rechargeable battery technology available today. What's more, Lithium Batteries are not subject to the "memory effect" that NiCd and NiMH batteries suffer from.
