Sony will release a new battery for the PSP Slim in the US next month that will last twice as long as the standard battery sold with the new version of the handheld.
The Extended Life Battery Kit will retail for $44,99 (£21) and will include a new 2200 mAh battery pack that Sony says will keep your PSP's juices flowing for twice as long. So it might actually last the length of a plane flight, at last.
The kit also comes with a new battery dock cover, available in silver and black, to allow your PSP to accommodate for the slightly thicker dimensions of the new battery.
For owners of the older, fatter PSP, Sony notes: "Those of you with the original PSP (PSP 1000) may recall that we offered an extended life battery pack (the stamina battery) previously, and this battery remains compatible with that system as well."
This would lead us to presume that the new battery will not be compatible with the old PSP, although it doesn't appear to say that on the packaging (pictured).
