Lithium-ion batteries power most electronic devices around the globe. However, you may have encountered certain consumer electronics with a lithium polymer battery. While it might not be immediately evident, there''s a significant difference between lithium-ion (Li-ion) and lithium-polymer (Li-Po) batteries.
Li-ion batteries come with a high energy density, which implies they can store a lot of energy. Additionally, they are portable and rechargeable. For example, a solar generator kit equipped with a 3,000 mAh battery will generally last longer than a solar generator with a 2,000 mAh battery. Nevertheless, mAh alone does not tell everything
For example, the mAh rating of a lithium-ion battery doesn''t equate to the same amount of power as the mAh rating of a lead-acid battery. This is because mAh is a measure of charge capacity, but the voltages differ between battery chemistries. A lithium-ion battery operates at around 3.7 volts while a lead-acid battery is around 2 volts. So a
So, for example, a typical AA Ni-MH rechargable battery has a nominal cell voltage of 1.2V. If you find one with a capacity of 2,000mAh, it would have a 2.4Wh rating. If you want to take a Wh rating and convert it to mAh, divide it by the voltage of the battery ; and multiply that by 1000. For example: A 90Wh battery that has a voltage of 12V.
The milliampere-hour is a small unit of measurement, with one milliampere-hour equaling one-thousandth of an ampere-hour (Ah). This means that a battery with a capacity of 3,000 mAh can supply 3 amps of current for one hour, or 1.5 amps for two hours, and so on. It is important to note that mAh is not the only factor that determines battery life.
mAh (milliampere-hour) indicates the charge capacity of a battery and how long it can power a device. The higher the mAh rating, the longer the battery is expected to last. How Does mAh Affect Battery Life? Now that we understand what mAh is, let''s take a closer look at how it affects battery life.
C-rate of the battery. C-rate is used to describe how fast a battery charges and discharges. For example, a 1C battery needs one hour at 100 A to load 100 Ah. A 2C battery would need just half an hour to load 100 Ah, while a 0.5C battery requires two hours. Discharge current. This is the current I used for either charging or discharging your

If not, you can calculate it as Volts x amp hours (Ah). example 1: an 11.1 volt 4,400 mAh battery – first divide the mAh rating by 1,000 to get the Ah rating – 4,400/1,000 – 4.4ah.
For instance, a 3000 mAh battery theoretically can give 3000 milliamps in an hour or 300 milliamps in ten hours. Importance of mAh in Daily Life. thanks to breakthroughs like solid-state batteries and advanced lithium-ion technologies. Understanding mAh in
NiMH batteries, while available in standard sizes like AA or AAA, are generally larger than Li-Ion options for the same capacity. Part 5. Capacity. Battery capacity, usually measured in milliampere-hours (mAh), determines how much charge a battery can hold. Li-Ion batteries often have higher capacity than NiMH. This translates into longer
If you''re comparing single batteries of the same type (alkaline, Li-ion, lead-acid, etc.), they''ll all have identical nominal voltages—and mAh would work to compare capacity. When the nominal voltages between two batteries are different, the mAh values are incomparable to each other. This happens:
The higher the mAh rating, the longer the battery will last before needing to be recharged. How does mAh affect battery life? The mAh rating of a battery directly relates to its capacity and plays a crucial role in determining the battery life. A battery with a higher mAh rating will typically last longer before requiring a recharge compared to
Tenergy 9V lithium battery: 1,200 mAh. What does mAh indicate? The mAh rating for each battery indicates its charge capacity and how long it can run a device.

To convert from electrical charge to energy, one multiplies mAh by the battery voltage. Most lithium-ion batteries have a voltage of about 3.8 Volts (notice, this is way less than the typical 120 Volts out of your home outlet). So if we take the iPhone 6 battery, its capacity is 1,810 mAh (look at the bottom of the battery photo).
Lithium-Polymer, or Li-Po refers to a lithium-ion battery that uses a polymer electrolyte instead of a liquid electrolyte. This enables the construction of pouch cells with different geometries.
With larger batteries, like car batteries, we usually use ampere hours, or Ah. There are 1000 mAh in a single Ah. mAh is calculated by multiplying the amount of time the battery lasts by the amperes of the discharge current. That may sound complicated, but it''s really not.
Depending on the type of battery, mAh consumption will be different. Still, one rule applies in most cases – the higher the mAh rating in batteries, the more electrical energy the battery can store. For example, before the release of the iPhone 6, the previous models were equipped with a 1500mAh lithium-ion battery. However, 4000mAh
