Lithium-ion cell sizes The most common lithium-ion cell is the 18650 (the numbers define the physical dimensions and shape as follows: 18mm in diameter, 65mm long and the 0 means it has a round cross-section) which is due to its widespread use in laptop battery packs.
What size do lithium batteries come in?
Lithium batteries are only sold in AA, AAA, and 9V sizes; however, their mAh ratings exceed every other non-rechargeable battery. One AA lithium battery ranges from 2,700-3,400 mAh, and will last a long time, even under heavy-use.
Are all lithium batteries the same size?
Lithium-ion cells have since become the standard in most tools and larger applications where their smaller size, lower weight and higher capacity greatly improve utility. Not all lithium-ion cells are the same, though; there exist different variations of anodes, cathodes, storage configurations, and chemistries.
How do I know what size lithium-ion battery I have?
If you multiply watts × time, you get joules. Given that one hour is 3600 seconds, then 1 Wh is 3600 watt-seconds, or (3600 joules/second) × seconds, which equals 3600 joules of stored energy in the cell. The typical way, though, to describe the capacity of lithium-ion cells is their charge capacity, or Ah.
What are the different battery sizes?
Sizes and Formats of cells and batteries
| SIZE | DIAMETER | WEIGHT |
|---|---|---|
| YYYY | 8.4 mm | 6.5 g |
| 1/2 AAA | 10.0 mm | 5.3 g |
| 2/3 AAA | 10.0 mm | 7.3 g |
| 4/5 AAA | 10.5 mm | 9.3 g |
Is aaa4 the same as AAAA?
They are not interchangeable. I’ve yet to purchase any item that uses AAAA.
What battery is smaller than 377?

| 7.9 x 1.65 mm | SR716, SR716SW, SR67, 315 | – |
How do I know what size battery to get?
Battery capacity is measured in milliamps × hours (mAH). For example, if a battery has 250 mAH capacity and provides 2 mA average current to a load, in theory, the battery will last 125 hours. In reality, however, the way the battery is discharged has an impact on the actual battery life.
Is 18650 the same as AA?
18650 Rechargeable Li-ion Battery: These are larger in diameter and in length than a standard AA battery size. The 18650 Li-ion battery is an extremely popular battery source for today’s flashlights since the 18650 battery carries so much power.
What are AAAA batteries used for?
AAAA batteries (commonly referred to as Quadruple-A or LR61) are smaller than the commonly used AAA and AA sizes. They are used to power small gadgets such as LED penlights, glucose meters, laser pointers, headphone amplifiers and powered computer styluses.
How do you find the mAh of a lithium battery?
Many batteries are not rated in Ampere hours (Ah), they are rated in milliampere hours (mAh). Milliampere hours are one thousandth of an ampere hour. To determine the Ah, divide the mAh by 1,000. It requires about 0.3 grams of lithium metal to produce 1 Ampere hour of power.
How do you measure a lithium ion battery?
Multiplying amperes X time will give you coulombs. With the specification one hour is equal to 3600 seconds; it means that one ampere-hour is 3600 ampere-seconds or 3600 coulombs/second X seconds, which is 3600 coulombs of stored charge in the Li-ion cell.
What is Wh capacity?
Capacity – Watt-hour (Wh):
Another way to measure the capacity of the battery is in Watt-hours (Wh). Wh is calculated by multiplying the number of Amps with the battery voltage. For example, a 12V100 (a 12 volt battery with a capacity of 100Ah) has a capacity of 12 x 100 = 1200Wh.
What are the 3 types of batteries?
There are three primary battery types available for consumer use. They are alkaline, nickel metal hydride (NIMH), and lithium ion. Each type has its pros and cons. Each one also has a distinctive place in technology history.
Why are 1.5 V batteries different sizes?
They turn stored chemical energy into electrical energy. And given their wide range of uses, it’s no surprise that many different sizes and types needed to be developed. Larger objects need more power. That meant larger, more powerful batteries had to be developed.
What Are No 7 batteries?
Cylindrical batteries

What can I use instead of AAAA batteries?
Direct replacements for AAAA would be E96, LR8D425, MN2500 and MX2500 . These batteries are exact equivalents for the AAAA battery, the only difference being the name.
Do quadruple A batteries exist?
The AAAA battery (usually read as quadruple-A) is 42.5 mm long and 8.3 mm in diameter. The alkaline cell weighs around 6.5 g and produces 1.5 V. This size battery is also classified as R8D425 (IEC) and 25 (ANSI/NEDA).
How many mAh is AA battery?
For example AA alkaline batteries typically have a capacity rating of over 2,500 mAh and AA NiMH batteries have rated capacities of only 1,200 to 2,000 mAh. But when it comes to actually powering an electronic device like a digital camera, the NiMH batteries will often run the device for three or four times a long.
Is a 626 battery Same as 377?
