Having that the above said, 18650 is overall a much better battery platform. It is capable of delivering much high load current than AAA (brighter lights), operate at a higher voltage (so you don’t need so many in series), and contain much more energy. 18650 does cost more, but has become very affordable these days.
Is a 18650 battery the same as AAA?
AAA Batteries vs 18650 Batteries
At first, AAA and 18650 batteries don’t have much in common – AAA batteries are cylindrical batteries 10.5 mm (0.41 inch) in diameter and 44.5 mm (1.75 inches) in length, while 18650 batteries are cylindrical batteries 18.6 mm (0.73 inches) in diameter and 65.2 mm (2.56 inch) in length.
Can I replace AA with 18650?
In brief: No, the 18650 cells can not be used in place of standard AA batteries, rechargeable or otherwise: The nominal voltage of the 18650 is significantly different from the 1.5×3=4.5V of the three AA cells, assuming those are connected in series.
Is a 18650 battery the same as a double A battery?
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 battery is the same as 3 AAA?
LR03 is the corresponding IEC classification, as AAA is the same battery but according to ANSI classification.
What brand of battery does AAA use?
East Penn Battery
Most batteries made for AAA are made by East Penn Battery.
What size is AAA battery?
10.5 mm
Sizes and Formats of cells and batteries
| SIZE | DIAMETER | HEIGHT |
|---|---|---|
| 4/5 AAA | 10.5 mm | 36.0 mm |
| AAA | 10.5 mm | 45.0 mm |
| 1/3 N | 11.5 mm | 11.5 mm |
| 1/2 N | 11.5 mm | 18.0 mm |
Is 18650 the same as 14500?
The only difference between the 14500 and 18650 is NOT the output, they both output at 4.2V or 600mA. The difference lies in the capacity, the 14500 at 900 mAh and 18650 at 3000mAh, which means that the 18650 will last about 3 times longer before needing to recharge is all.
Can I use CR123 instead of 18650?
Rechargeable 18650 batteries will typically last longer, but do the math for the batteries you are considering. Keep in mind CR123 batteries are typically cheaper than rechargeable 18650’s, but two CR123’s equals one 18650. There are also some rechargeable CR123 varieties if you desire.
Are 18650 batteries bigger than AA?
No, they are slightly larger and have completely different formula. The 18650 battery is a lithium-ion cell classified by its 18mm x 65mm size, which is slightly larger than a AA battery. They’re often used in flashlights, laptops, and high-drain devices due to their superior capacity and discharge rates.
What battery equals 18650?
The most well-known ostensible voltage for pretty much every NiMh or NiCD AA battery is 1.2V-1.5v. 18650 batteries have an ostensible voltage of 3.6V, so this implies you would require 3 AA batteries in arrangement design (joined start to finish) to get a similar voltage as only one 18650.
Can you charge 18650 batteries in a normal charger?
Yes, just with an acceptable charging voltage and current. For most 18650 battery cells ( not the LiFePO4), the charging voltage is 4.2V, and the charging current is about 2A. There are some general 18650 battery chargers working well.
Can I use AA batteries instead of AAA?
AA and AAA batteries are both 1.5V nominal (for disposable) and 1.2V nominal for rechargeable (usually NiMHs.) As long as the current draw doesn’t exceed the AAA’s ability, you can use a AAA in place of a AA by bridging the gap (may need some padding around it as well to keep it aligned.)
What is inside AAA battery?
The average alkaline AAA, AA, C, D, 9-volt or button-cell battery is made of steel and a mix of zinc/manganese/potassium/graphite, with the remaining balance made up of paper and plastic. Being non-toxic materials, all of these battery “ingredients” are conveniently recyclable.
Which is best AAA battery?
The 5 Best AAA Batteries
- Energizer Ultimate Lithium Battery.
- Duracell Ultra Power Alkaline Battery.
- Sanyo Eneloop Rechargeable Battery.

- Kirkland Signature Alkaline Battery.
What is the mAh of AAA batteries?
Use
| Chemistry | IEC name | Typical capacity (mAh) |
|---|---|---|
| Alkaline | LR03 | 860–1,200 |
| Li-FeS2 | FR03 | 1,200 |
| NiMH | 1⁄2 AAA 10.4mm 22.7mm | ~350 – 1,000 |
| Li-ion | 1⁄3 AAA | ~100 |
Are triple A batteries good?
They are good quality, a fair value and of course warranty is just a phone call away. The battery truck drivers get formal training, have expensive diagnostic equipment and can tell when it really needs to be towed to the mechanic. Where I live AAA uses Interstate..
How many volts is a AAA battery?
Generally, Panasonic eneloop AAA batteries have an initial voltage of around 1.2V. Appliances and devices that require AAA batteries are usually designed to work within the range of 0.9 to 1.5V.

Is there a battery smaller than AAA?
An A23 battery is cylindrical and somewhat shorter than a AAA battery, measuring 28.5 mm long and 10.3 mm in diameter, with a typical weight of 8 grams. An A23 battery is an 8-cell device with a nominal voltage of 12 V.
How many amps is a AAA battery?
An AAA cell puts out 1.2 to 1.5 volts, and it’s designed for relatively light loads, 0.1 amps or so maximum.
