Update: A picture tutorial is now available here.

A quick story resulting in a quick hack job… LordLeXaT’s PSP battery broke, and with no money to buy a new one, he turned to his MacGyver box set to determine the best possible route… And the result:

What you see above is a standard Nokia battery (BL-5C) pack used with the original PSP battery control board. So now that all is said and done, LordLeXaT has a longer lasting battery than most of you, or so he says…

“The battery is lighter and has nearly 150% lifetime of the original 1800mAh PSP battery, and by the way, the text of the Nokia battery reads 1020mAh.”

We don’t have a tutorial for you, but for the most part, it seems straightforward. And please, exercise caution should you attempt this battery mod yourself.

Squeeze extra juice from your PSP battery life with Torch’s Hold+. Really, it’s simple — when the hold switch is on, your battery power stays strong.

Here’s how Hold+ works…

• Switches off the LCD backlight.
• Switches off the actual LCD screen. (This is important because the backlight and actual screen are two different things. You can have an image being displayed on the screen while the backlight is switched off, such that you can see the image if you use a flashlight. You can also have the screen switched off while the backlight still illuminates the powered off screen.)
• Under clocks the CPU to 61MHz (Sony has changed the clock speed functions such that only certain combination of speeds work correctly. Simply trying to under clock to arbitrary values will result in the CPU simply running at the stock speed. I have verified that Hold+ successfully under clocks to 61MHz.)
• The original screen brightness and clock speed are restored when the Hold switch is released.
• Prevents the PSP from going into suspend mode if you accidentally push the power switch too far when turning off Hold mode.
• Allows operation of the PSP with the display turned off, to change volume, skip songs etc.
