Small battery question

Gamefreak271 · Post by **Gamefreak271** » Wed Apr 26, 2006 5:46 pm

I have finally ordered my 8.4V battery and it came a few days ago.I decided to charge it but not all the way. When I checked the voltage it was 9.5-9.6V. Now I'm too afraid to hook it up to the psone screen because it will most likely fry it. Please can anyone help me?

hmmm...well, I know that when you charge batteries, they go up for a little while (usually on NiMh, it's .1V, and on li-poly, it's as high as .6V, I believe).

What kind of battery is it? If it's Nimh (which it most likely isn't...an 8.4V NiMh pack has 7 cells, meaning .7 extra would only make it 9.1V) then you can remove a cell. Check to see if it's definitely an 8.4V battery and not a 9.6V. 7 nimh cells, if it is NiMh.

If not, then I don't think there's much you can do, really. Not that I know of, at least.

don't worry about it, the voltage will go down under load (powering an N64p)

It is a Nimh battery. Here is the link if you want to see it.

You sure about that? How much will the voltage drop during power up?

when i tested my 8.4v NimH battery alone, it was around 9.6v. when it was powering an N64p, it was 8.4v. BTW, psone screens don't fry at 9.6v, they just don't work right with that voltage
