In Embraer 145 and Boeing 777 I mean material, recharge cycle, nominal current and voltages. From the comments I don't understand the difference if the plane is turboprop or turbofan.

    $\begingroup$ Are you looking for battery capacities or discharge profiles for a start (assuming an S/G on smaller turbofans and turboprops). Your question just isn't very clear on what you are looking for. $\endgroup$ – selectstriker2 Jan 16 '18 at 4:19

    $\begingroup$ Is your question about the batteries being Li-ion or Lead acid, etc, as explained here? $\endgroup$ – mins Jan 16 '18 at 8:20

From this Concorde battery page, the Embraer E-145 can use a 44 Ah, 24 VDC Lead-Acid batter: Concorde RG-422

The Embraer E-145 can also use Ni-Cd batteries.

The Boeing 777 uses Ni-Cd batteries as well: Boeing 777 Saft Batteries
