found accurate DeWalt 28/36 V battery specs (cells are made by A123 Systems)

Form Factor: cylindrical 26650 (26 mm diameter, and 65 mm in length)
Voltage: 3.3 V nominal, 3.6 OCV
Capacity: 2.2Ah capacity minimum
Mass: 70 g
Internal DC impedance: ~11 mOhm
Power Density (5s pulse) >3500 W/kg
Energy Density ~120 wh/kg
Cycle life (100%DOD at 1C charge, 5C discharge rate) >1000
Recommended Temp range -20C to 60C


I tested an XRP battery and DC9180 LiFePO4 battery with a cordless grinder DC415 and they both yielded the same amount of cuts (10 1/2 across 1/2" rebar with 2mm disc)

Battery weight:

18V = 1.7lbs
28V = 2.0lbs
36V = 2.4lbs

Confirmed, Ridgid uses E-Moli 18650 cells, 1450 Mah

Spec sheet pdf

I bet the same batteries are used in Milwaukee 18v and 12v stuff.

Thanks LuxLuthor of Candlepower Forums for pictures.

Updates: cells in Bosch 36v stuff is Sony SF-US18650-VT, 10S2P configuration, 1100 mAh per cell.

Makita uses Sony SE US18650-V 1500 mAh which has a lower max discharge current than VT version.

New 18v Bosch LiIon is 2.6 Ah, unconfirmed, that makes it 1300 mAh per cell.

Talked to a Dewalt rep, new Porter Cable li-ion drills use Sony SF-US18650-VT 1.1 Ah cells. Unconfirmed.

Also was told new NiCd XRP batteries, also called "generation 5 XRP" will have a cell balancer circuit board inside.
