Anyone know what the absolute highest capacity rechargable AA batteries currently available are? And where are they available in the UK? I currently have 2300 MAh rechargables.

There have been no new breakthroughs in NiMH chemical technology, and no recent improvements in the manufacturing process. All recent capacity increases also come with the addition of increased internal resistance. It is market pressure that has caused the increased numbers, not better technology (they could have released 3000mah NiMHs on day one if they thought it was safe). This might be fine for a battery you plan to use in a remote control, but for high drain applications it mean your battery will get HOT, it will lose its capacity fast, and when it dies (relatively quickly) it is likely to be a catastrophic failure.
I have some nice MaHa Powerex cells (2300mah) that I plan to use until they die, then I will be very picky about what higher capacity cells I purchase, if any.
Direct-methanol fuel cell. So far the production and use of these has been somewhat inefficient, however Sony has developed a more efficient way of making these sorts of fuel cells.fade posted on Dec 17 2005 at 08:16 PM said:I've read that sony are developing some new kind of battery technology for thier PSP, cant quite remember what it was called though.
