Umm… so, why is this good? Still have to buy the battery pack, just now you have to pay MORE to get the rechargables.

Well, thats definitely not 3.6 volts anymore.. a little concerning. Plus, I wouldnt dish out US $45 to tear apart a good battery and put in duracells, heh. Interesting idea, though.

it is 3.6, each recharable battery is 1.2 .. 1.2 * 3 = 3.6
it costs 45 bucks to make this?.. way too much.. but think about it.. if you can get some really long lasting batts it would rock

Actually mosts rechargeable batteries are 1.2 Volts so its allright. But I still think its too much to pay.

the concept of this is that there might be a possible way to get something to last longer with a longer charge hold on diff batterys

duh :)

Well maybe when your battery is unable to hold a charge any more. It would cost less to just do this. I don’t think this is ment to be better than the original battery. I don’t see why every one has to bash everything that is posted on this site.

this would last 1/2 as long as the stock battery pack. The stock battery pack is 1800mah and the highest AAA batt is 750-1000mah. unless you can fit 6 AAA batts in there it was much better with the stock batts.

If you can’t tell I have already looked into doing this.

#6 you are rigth, people do mods/hacks/write apps, and other people bash, if your just gonna bash go talk as much crap you want in a aim chat room. This mod can actually help people that have dead batteries… I dont think you can fit 6AAA bateries in ther, theres not enough room

#7 But since there are 3 batteries wouldn’t it be 750×3=2250mah. I’m just asking, I really wouldn’t know how that works.

#9, I think it is still 750mah. I notice some rip off 29.99 psp combo package has something like an external batter pack. I also notice that the connector is exactly the same external batter pack I got for my Toshiba E740 ppc. Since the external power takes 5V so it was ok to hook it up with 4AA rechargeables. Since AA are now around 1700 I would say it almost reach the same capacity with the stock pack. However… if you guys race ele RC cars you will know that there are 3300 (or even higher) sub-C battery for sale out there. So technically you can create a battery pack that last 2 times the stock pack.

with 3 AAA batts you can have eather 750mah 3.6v or 2250mah 1.2v. If you had 6 AAA batts you could get 2250mah 3.6v.

You can find AA batts that are 2500mah but there isn’t enough room to fit 3 inside the psp.

I already have a 12v 24 AA batt power brick that I can plug my car charger into. I figure that should last me a good 20+ hours. I plan on using it on long plane trips.

oops. With 6 AAA batts you would only get 1500mah 3.6v. You would need 9 AAA batts to get 2250mah 3.6v.

I’m gonna bash the people who are bashing the people who are bashing this product. This concept is just plain gay. Kiddies, if you need a new battery just lift fiddy bucks out of dad’s wallet. Or go sell some ass to the guy in the white panel van.

3 photos without any explanation?
I fail to see any tutorial in this post.

peopl are bashing thigs without even knowing what they’re bashing. at least I ask for more info before saying it’s useless.

why dont tntpsp post a little result of this batterie trick ?
like this we will all know if is good or not ! but is true is not so bad , if some have already dead batterie and have some rechargable batterie sleeping some where is a good trick !

I think the key here is that you could easily get batteries that are 800Mh and only take 15 min to recharge.

what I would like to know is what the stock cells look like and what kind of batts they are. It would be easier to find a real upgrade that way.

I really don’t see the point of this. 750mAh instead of 1800? Next to that I don’t think it’s a good idea to replace the Li-Ion batteries with Ni-Mh, because the electronics in the battery is set for Li-Ion with a capacity of 1800mAh. In other words..WHY!

Wait a minute! This guy probably thought he would get 3* 750= 2250mAh…..hi hi ha Ha Ha HA HA HA HA….stop it it hurts!

…ha ha.. so he just decreased his playing time from 6 hours to 2,5 hours… Who’s your daddy!..It still hurts Whaahaaahaha

Here you go guys 1800mAh AAA rechargeable batteries. Now quite complaining. Some times if you do a google search you my learn something. Instead of spitting your bullsh** logic like you know something.

And what I’m reading at some places there are 2300mAH AAA rechargeables too.

Yea, but what if we actually can remove those batteries from the pack? This would be good if we want to change batteries when the others are dead. Maybe this would actually cost less than buying another battery. And would last very longer if we have plenty of batteries in spare.

Cuz when your traveling, normal batteries(non rechargeable) are an advantage. Like the old gameboys. But if you’re somewhere where you can recharge your pack, it’s useless to have normal batteries. See what I mean?

Even if you have 1800mAh I don’t think it’s good to replace the Li-Ion battery with a Ni-Mh battery. Still remains the fact that this guy used a 750mAh battery.

much respect,,,, i don’t know if i’d do it but much respect>>>>peace out.

those “2300mah AAA” look like a missprint to me. The top of the page says “AA NiMH 1800mAH batteries” and the bottom of the page says “2300mAH, AAA Size” with the same part number. The highest AAA I have ever found were 1000mah max.

And yes if the electronics of the stock batt were made for Li-Ion cells then you can just swap in Ni-Mh cells and figure everything is going to work correctly.

The best thing to do would be to build a 5v C or D cell power pack and charge it outside of the psp.

Whats the big deal with just recharging the thing every 7-10 hours of play!? If you play for 7 hours straight on your PSP… you’ve got a problem….

it’s a good idea, but wont take off

simply the reasion why I did it was I baught a used battery from a store and after two uses it stoped working. So I desisded to open it to find out how it worked after looking around to find a High Mah battery I gave it a try I know that this battery is crud but the second prototype is going to look better also im trying to see if the life of this battery will last as long as the stok battery.

Also buy used batterys there cheep and give it shot you dont need a lession plan on this once you open the old batterys up Youll know what to do just take your time….tntpsp….out

This demonstration means that we can carry one psp plus battery pack holder, and a lot of rechargeable AAA batteries that is cheaper than li-ion batteris. That’s good idea. Someone in some place should have been waiting for such a stuff.

mmmm….i have 1.2v 2000mah recharable AA batteries

Is nobody listening? I don’t think it can work “good” if you use Ni-Mh instead of Li-Ion since the electronics is programmed to charge a Li-Ion battery. I don’t know if you guys know your electronics but the charge curve for Li-Ion is different that Ni-Mh batteries. This could result in very very hot batteries with a charge of nothing. Even if you would place 3 AAA batteries Li-Ion of 2000mAh there is a big change you would still get the same capacity as the 1800mAh battery because the electronics doesn’t know better than having a 1800mAh battery inside to charge. This could result in that the PSP shuts off because it thinks the battery is empty but in reallity it has stil some charge left.

#34 Thats why you take them out and charge in the battery charger for those batteries. Even if it did charge in the PSP it would probably take as long as the normal PSP battery. But it only takes an hour in the other charger. Is this helping anyone or are we all going to sh*t on this guys work like you have all been doing.

#35 What do you mean take them out? The batteries are soldered inside the housing.

At #34
“electronics doesn’t know better than having a 1800mAh battery inside to charge”

Really talkin alll that shit for nothing….

Actually it does. Sony’s big plan is to sell these higher ****mAh batteries and change the clock speed on the psp from 222mhz to 333mhz. Longer Battery life!

Supply and Demand
Most likely the main reason they didn’t release the psp with the required ****mAh was the demand for the rare battery was higher then the supply! If you dont understand S & D go look it up in a book!

I wanna make sure your listening SO.. make sure you read this twice!

#36 your acting like you have to solder directly to the battery. Like you can’t just solder your own metal pads in or something. This is his prototype not his finished idea yet. Maybe it was just easier to solder to the battery to see if it work instead of doing all this work for nothing. Thats what I would do instead of throwing away all my time making something that doesn’t work.

I was looking around, check these out. http://www.duracell.com/products/prismatics.asp?id=41& Prismatic batteries, rectangular prism batteries, I couldnt find any statistics about them, but my friend has rechargable ones in his cd player. I think you might be able to fit 2 layers of 3 in the battery pack…

#39 those batteries look interesting. And I think they are Li-Ion Batteries too.

MAN PEOPLE ARE DOING EVERYTHING NOW A DAYS BECAUSE THEY ARE BORED AND WHY IN THE HELL WOULD YOU LIKE TO TAKE A 40 DOLLAR BATTERY TO PUT SOME CRAPPY BATTERYS…….ITS JUST POINTLESS JUST RECHARGE LIKE NORMAL PEOPLE

Your Stupid!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!Why would you want to do that!Its lame!!!!!!!!!!

hey dips its a damn good idea realy… just like a game boy……..kinda klever

tntpsp, just ignore those bashers. bashers, shut up already.

I read this site about rebuilding a notebook li-ion battery pack:
http://www.electronics-lab.com/articles/Li_Ion_reconstruct/

The battery is 10.8V 2600mAh and inside the battery are 6 3.6V 1300mAh li-ion cells. The cathode+ side of a cell (cell A) is connected to the anode- side of another cell (cell B), ending up with 3 “pairs” of cells. The cathode+ of each pair then are connected together, same with anode-, then to the control pcb inside the battery.

http://www.electronics-lab.com/articles/Li_Ion_reconstruct/photos/image_4_f.gif

This becomes 3.6V 2600mAh

-3.6V 1300mAh+-3.6V 1300mAh+

This becomes 7.2V 2600mAh
-3.6V 1300mAh+-3.6V 1300mAh+
-3.6V 1300mAh+-3.6V 1300mAh+

This becomes 10.8V 2600mAh
-3.6V 1300mAh+-3.6V 1300mAh+
-3.6V 1300mAh+-3.6V 1300mAh+
-3.6V 1300mAh+-3.6V 1300mAh+

So, using only three 1.2V 750mAh batteries, connected together, can only become 3.6V 750mAh

To all those dumbass bashers, this is great discovery for when your original stock battery finally dies and you dont want to fork out $45 to buy a new one.

Keep up the good work, tntpsp.

I’m going to do this, the only reason I will is because batteries have limited recharges, and my original 1800 mAh one has roughly a 30 minute charge. Anyways, I suggest doing it, it won’t waste money if your battery is already dead!
