hay everybody, gamerlolwind here
i have some questions on my ps2p that I'm making which i really can't find an answer for i have searched a lot about it but no possible answer only mixed options or no good info at all.

my ps2 will need an 8.5v/9v battery,
i heard that the best battery type is dvd portable 9v.
i found this on amazon com. when i typed portable dvd battery i got this as the only battery choice on top list.

is it okay for me to use this for my ps2? or should i use my adjustable reg to change it's volts?

it has 9V 23WH

not sure about mah. is it V/WH = MAH?

should the mah be 5400 or over?
and should it be acatly 8.5v? cause i read that using a 9v can shorten some functions of the ps2?

and how do i make it fit in the ps2 socket dc?

also i found out that the playstation charger tips are C type all of them (Psx/Ps2/PS3? and Psp)
so if i take an placation c tip and solder it on my dvd battery end it'll fit in the ps2?
or i can get an C type adapter end that i can attach on the dvd battery's plug that goes into the ps2, if these kind of adapters exist that is?

some help, cause i really, really, need it thanx
