Do you think you know AA batteries? Think again, because there are lots of AA batteries out there. If you don’t trust us, check out the list below!
mAh AA Battery Comparison
Let’s compare AA battery with other batteries here
1. Zinc Carbon
The nominal voltage of zinc carbon batteries is 1.5V, with capacities of 500-600 mAh for AAA and 600-1600 mAh for AA batteries. They aren't powered by a rechargeable battery.
The age, temperature, discharge current, and other factors all affect a battery's capacity. Zinc carbon batteries are cheap and long-lasting, however they have a short storage life (they leak eventually), can't withstand higher currents without losing capacity, and other disadvantages.
2. Li-Ion AA
Lithium-ion AA and AAA batteries are rechargeable batteries with voltages ranging from 3.2 to 3.7 volts and capacities ranging from 350-600 mAh for AAA and 600-2000+ mAh for AA batteries, and are created from a variety of lithium-ion chemistries.
Li-Ion AA and AAA batteries are not backward compatible with 1.5V AA and AAA batteries due to their 3.2-3.7 volts.
Certain gadgets accept both 1.5V non-rechargeable Zinc-Carbon, alkaline, and other 1.5V batteries, 3V non-rechargeable lithium batteries, and 3.2-3.7V rechargeable batteries because lithium-ion AA and AAA batteries offer significant benefits over non-rechargeable AA and AAA batteries.
LED torches, cameras, and other similar gadgets are examples of such equipment.
3. NiCd
Cadmium Nickel AA and AAA batteries are among the most ancient rechargeable AA and AAA batteries on the market.
NiCd batteries have a nominal voltage of 1.2 volts and a capacity of 300-500 mAh for AAA and 600-1000 mAh for AA batteries.
Although NiCd batteries are economical, durable, and capable of high currents, they have a strong memory effect, contain dangerous metals, and can only be charged and discharged a limited number of times.
These are the reasons why NiCd batteries are being phased out in favor of low-self-discharge Nickel Metal-Hydride (NiMH) batteries.
4. Li-SOCl2 AA
Non-rechargeable Lithium Thionyl Chloride (Li-SOCl2) AAA and AA batteries have a nominal voltage of 3.5-3.6 volts, an OCV of 3.65 volts, and a capacity of 600-800 mAh for AAA and 2400-2700 mAh for AA batteries.
AAA and AA batteries containing lithium thionyl chloride (Li-SOCL2) are incompatible with 1.5V batteries and should not be used in devices that only accept 1.5V AA batteries.
On the other hand, batteries that can be used in both 1.5V and 3.0-3.7V devices have a high energy density and a long shelf life, which may aid these products.
5. NiZn AA
The nominal voltage of nickel zinc (NiZn) rechargeable AAA and AA batteries is 1.6V, with capacities of 500-700 mAh for AAA and 1500-1800 mAh for AA batteries.
NiZn batteries have good discharge properties and have a low self-discharge rate.
Although NiZn batteries are typically backward compatible with 1.5V batteries, if four NiMH batteries (4.8V) are replaced with four NiZn batteries, some devices designed for NiMH cells (1.2V) may be damaged (6V).
6. NiOOH AA
Nickel oxyhydroxide (NiOOH) is added to manganese dioxide in AAA and AA batteries, resulting in a 1.5 V normal voltage and a 1.7 V OCV voltage under high drain operation.
NiOOH AAA and AA batteries have the same capacity as ordinary alkaline batteries (1000-1200 mAh for AAA and 2200-2700 mAh for AA), but they can be drained at higher currents without losing capacity, which makes them ideal for high-drain devices such as cameras and other picture equipment.
7. Lithium 1.5V AA
Several manufacturers produce lithium-ion batteries with control circuits that drop the battery's inherent 3.2-3.7V down to 1.5V, making them compatible with 1.5V AA and AAA battery devices.
AAA batteries have a nominal capacity of 400-600 mAh, while AA lithium 1.5V batteries have a capacity of 1000-2000+ mAh.
On such batteries, the charging port/receptacle is either a USB charging connection or a micro-USB charging connection.
8. Li-FeS2 AA
Non-rechargeable Lithium Iron Disulfide (Li-FeS2) batteries have a normal voltage of 1.5 V, a huge capacity, and a shelf life of up to or even more than 20 years.
The Open Circuit Voltage (OCV) of Li-FeS2 batteries is 1.8V, while the real voltage lowers to 1.5V when the batteries are depleted.
AAA Li-FeS2 batteries have a capacity of roughly 1100-1300 mAh, whereas AA Li-FeS2 batteries have a capacity of around 2700-3300 mAh.
AAA and AA Li-FeS2 batteries must perform reliably in high-drain and stand-by applications, even after years of inactivity.
AA Battery Voltage
AA batteries start out at 1.5 volts and rapidly fall in voltage as they are used up. Even if the batteries still have a lot of charge left, if they drop below 1.35 volts, they look to be dead.
When used to power remote control, one AA battery will last 240 minutes, 95 minutes when used to power portable speakers, and only 38 minutes when used to power an RC toy. According to Roohparvar, the Batteriser can extract 1,185 minutes from a remote (5 times more energy), 570 minutes from portable speakers (6x), or 355 minutes from a remote control toy (9x).
What is mah in battery?
The milliamp Hour (mAh) is a power measurement unit that is used to track the amount of (electric) power used over time. It's a common way for determining a battery's energy capacity. The larger the mAh, the bigger the capacity or life of the battery.
The higher the number, the better the energy storage capacity of the battery. This, of course, leads to longer battery life for a certain app.
If the power demand rate is constant, this can be used to estimate how long a device will last (or average). You can learn more about the Ampere Hour here. For example, a 3000 mAh battery may operate a 100 mA (milliamp) device for 30 hours. A device that consumes 200 mA will only last 15 hours.
