The gaming accessories company Datel has released 2 new batterys, one is Max, which is just a replacment incase your battery that came with the PSP died, or is turning weak. The other is called the "Tool", Which acctully will downgrade any psp without making your own Pandora(MS, and Battary), this will work without anything special. It will also unbrick any psp, as it turns the psp into "Service Mode". This battery can also get you down to "FULL 1.50", no nockoffs like pandora. So if you want to downgrade or upgrade your psp to a different firmware or Custom firmware, which ussually cause bricks. Also can anyone say nockoff of Pandora to make money???
Well both batterys sell for about $25 US which is the price of regular batterys.
