Acidmods have posted a tutorial on how to make a battery mod for your PSP with AAA batteries

Personally i prefer the 2600mah battery (http://www.play-asia.com/SOap-23-83-2pz-71-bg-49-en-84-j-70-1jka.html)(nearly 50% more powerful than the original Sony effort.

Looks like a very effective mod...knowing me, however, I'd just break my PSP, but if someone gets it working let us know :D

I already have one! £3 from Gamestation. it plugs into the yellow AC and takes 4AAA.

[bah]

Hrms...

The psp's battery is a single cell li-ion, 3.6v.

3 rechargeable AAAs at 1.2 volts would work.

3 Non rechargeable would be 4.5, this wouldn't be enough to damage something in the psp I hope?
That image looks like a direct connection to the 3 AAAs in series, and the batteries are 1.5v non rechargeables.

The charger is 5v, it goes to a different port but i have no knowledge of how the innards are wired after that.

Seems to work for him so i guess its not a problem, at least in the short term.

this is pretty good. ...i wonder why he decided to do this lol

[xg917]

yea 4 real. does it last longer than the original sony batt.?

[Veskgar]

I'm guessing you'd only get about 4 hours with this. Pretty neat as a fun mod but not effecient enough to take seriously.

I just use the STAMINA battery from SONY. Charges fast and lasts long.

Check the source post and you'll find out that new batteries will only last about an hour. He's also using AAA not AA.

I also wonder if the extra volts might shorten the life of the PSP, but perhaps the circuit board that reads and reports battery level is also trimming down the voltage to the appropriate level.

That battery mod look well good. I have rechageable AAA batteries that just takes 15 minutes to charge up. As they are 1000mah each putting them in a modified Sony battery should crank that up to 3000mah, that should result in nice long run times on the PSP.

an hour of battery isnt impressive but its still a nice mod.

[psp411]

its a cool mod but it wudnt giv u even half of the playing time dat psp's normal battery wud give u... ive done tests on a bunch of different mods that ive created maself( and some that ive found on the internet). ps's current draw is rly high( for most portable electronics anyway) and to use AAA batteries in it wud just giv u like 20+ minutes to do what u gotta do. This is the main reason why i try not to work with anything below AA b/c AAA die too quickly. Whenever i get enuf time, ill post my own homemade mod for a psp charger.
:D :cool:

YKB:
If the batteries were in parallel then you would have the equivalent of a 3000mAh official battery.

They may each supply 1000mAh, but only at 1.2v per cell compared to the original battery's 3.6v.

The 3 cells, each at 1.2 volts, are connected in series to give the needed 3.6v.

Amps x Volts = watts (actual energy use)

You may have 3 times the batteries, each with 1000mAh, but your also drawing 3 times the volts. Meaning 1 useful mAh of battery life to the psp takes 1mAh of life from each battery, not just 1 of them.

You end up with the battery life of a single 1000mAh (or so its rated) battery.


YKB: Yeah, i mentioned about the high voltage when using non-rechargeables (1.5v each Vs 1.2v for rechargeables) in my earlier post in the thread. Hopefully the psp can handle the extra voltage being supplied directly via the batteries. The charger supplies 5v, but I don't know how it is wired up inside the unit.

[Shrygue]

Okay....however, each of my 1000mah AAA batteries are 1.5v making it 4.5v in total or does that circuit board perhaps restrict that to 3.6v total?

This is the externel charger i have... It lasts about 4 hours and you can pick them up for about £3.

I got the same exact thing from Lik-Sang.
About US$8 with shipping.
But now you can't order from them.... :mad:

Who makes GP Ultra brand batteries anyway? Those look like 100yen store batteries. HAHA...

I use those...
