So what kind of lithium ion cells are they using?
In the Sub-Compact M-12 battery 48-11-2401, Milwaukee uses the Samsung INR18650 13Q Cells.
In the Sub Compact 12v battery R86048, Ridgid uses Sanyo UR18650SAX Cells.
In the compact battery BAT609, Bosch uses the Samsung INR18650 13Q Cells.
 In the compact battery 130156001, Craftsman uses the Samsung INR18650 13Q Cells. In the DC9180 battery, Dewalt uses the A123 APR18650M1 Cells. In the compact battery BSL1815X, Hitachi uses the Sanyo UR18650SAX cells. In the compact battery BL1815, Makita's uses Sony SE US18650OV, in the BL1830, Makita uses Sony SE US18650VT.  In the compact battery 48-11-1815, Milwaukee uses Samsung INR18650 13Q Cells. Or the E-Moli IMR-18650E Cells.  In the M-18 XC battery 48-11-1828, Milwaukee uses Samsung INR18650 13Q Cells.  In the compact battery R840084, Ridgid uses E-Moli IMR-18650E Cells. In the compact battery P103, Ryboi uses Samsung INR18650 13Q Cells. Bosch, Craftsman, Milwaukee, and Ryobi all use the same Samsung INR18650 13Q cell.
Bosch - BAT609, $69. That's $13.80 per cell. (5 cells)
Craftsman - 130156001, $89. That's $17.80 per cell. (5 cells)
Milwaukee - 48-11-1815, $69. That's $13.80 per cell. ( 5 cells)
Milwaukee - 48-11-1828, $119. That's $11.90 per cell (10 cells)
Milwaukee - 48-11-2401, $40. That's $13.33 per cell (3 cells)
Ryobi - P103, $49. That's $9.80 per cell. (5 cells)
Makita and Hilti use the same Sony SE US18650VT cells.
Makita - BL1815, $79. That's $15.80 per cell. (5 cells)
Makita - BL1830, $99. That's $9.90 per cell. (10 cells)
Hilti - 360383, $189. That's $15.75 per cell. (12 cells)
Dewalt - DC9180, $149. That's $12.41 per cell. (12 cells)
Hitachi - BSL1815X, $79. That's $15.80 per cell. (5 cells)
Ridgid - R86048, $40. That's $13.33 per cell. (3 cells)
Ridgid - R840084, $69, That's $13.80 per cell. (5 cells)Well I'm not sure If I should give Ryobi (TTI) credit for using the same Samsung cells as Milwaukee (TTI) Craftsman (TTI) and Bosch? Or frown at TTI and Bosch? One thing is for certain, your paying a whole lot less for the same battery technology in the Ryobi P103 battery.
Even though the Dewalt DC9180 battery is the second most expensive battery, it is one of the 3rd least expensive per cell. At least Dewalt is not charging you more for the name! (Hilti) Plus your getting the best Lithium Ion Chemistry available for power tools.

Are all of the cells above the same mAh rating? I would be curious to see the cost per power of these batteries. Technological differences nonwithstanding.

Each manufacture has their own specs. Different Ah ratings, and different peak and nominal voltage ratings per cell.

Hi everyone, i'm a newbie here.
Just wonder why all the Samsung INR18650 13Q looks the same. The codes on the cells are all showing 13Q and 088. Does any one know what it stands for? You can see the codes on Sony and Moli are different.

I'm not sure I understand your question? The Samsung cells are all the same, because they are all the same cells just put in different manufactures shells.

JC, what I mean is, don't the manufacturers add the codes on the cells with certain meaning? such as a batch code? You can see the batch codes on the Samsung are the same. Is it possible that they are the same batch (or even same cell, who knows).

some do, some don't, what difference does it make? They can be serial number, QA person id or timestamps. They are all from the same batch, as capacity varies from batch to batch and manufacturers try to match the cells as close as possible.

Samsung put up their li-ion cell website. Also took apart the Bosch 10.8 battery, uses Samsung 13650-13P.
13Q and 13P are identical except the max discharge rate, both are 1.3 Ah @ 260 mA discharge. 13P is 10 Amps and 13Q is 18A. So all the 18v 2.6 Ah Bosch/Milwaukee/Ryobi etc stuff should have about the same torque at equal RPM. Milwaukee might be weaker because they use PooPoo motors.

Anyone ever realize that the Craftsman batteries are marketed/claimed to be 19.2v.
But, given the info here about what they're made of, that can't be.
The Samsung INR 18650-13Q battery cell (of which there are five) is a 3.6v cell
3.6 * 5 == 18v
The battery is marketed as a 19.2v battery -- which, given the inputs, is impossible.
This smells like a class action lawsuit to me. They're claiming something that can't be, and we're all 6.67% worse off due to their misleading practices...
All of the other batteries which are using 5 of those cells are all clearly stated to be 18v units -- except for the Sears/Craftsman/DieHard ....

It's nominal voltage is 3.6v, fully charged it's closer to 4.2v. Leaving you fully charged at 20v. So it's not a total lie, at some point it crosses the 19.2v threshold.

once again, great pics and well done with that information.
You go to a lot of effort.
Can you tell me please if you know what brand and number of cells are in the Hitachi EBM1830 3.0AH HXP packs?
Thank you.

19.2 volts can be reached when the circuit is open (no load), it is the state when the battery is fully charged (3.8V-3.9V/cell) Under load conditions the battery voltage drops to 18V (3.6V/cell) until cut-off (2.7V-3.0/cell), lower voltages can destroy Li-Ion batteries, that's why they have protection circuits.

Nope, they use Molly cells |

hi
A123 APR18650M1 cell have nominal voltage of 3.3 volt and 1000ma this give a 3.3 w/h, output 30amp discharge
sony se us18650vt cell have nominal voltage of 3.7 volt and 1100ma this give a 4.07 w/h, output 15Amp discharge
sony se us18650vt cell have nominal voltage of 3.7 volt and 1500ma this give a 5.55 w/h, output 15Amp discharge
sanyo UR18650SAX cell have nominal voltage of 3.7 volt and 1250ma this give a 4.63 w/h, output 20Amp discharge
Samsung INR18650 13q cell have nominal voltage of 3.6 volt and 1300ma this give a 4.68, w/h output 18Amp discharge
Samsung INR18650 13p cell have nominal voltage of 3.6 volt and 1300ma this give a 4.68, w/h output 10Amp discharge
E-Moli IMR-18650E cell have nominal voltage of 3.8 volt and 1400ma this give a 5.32w/h, output 20Amp discharge
dischage rate give you the torque possibility of battery,but the real workhorse is the watts/hour it give you the real capacity of the cell,the power output in the time.
you can make the cost per w/h of battery yourself
have a nice day
