NiMh with very low self-discharge

[altis]

Up until now, the main advantage of rechargable Li-Ion batteries compared with NiMhs has been their low self-discharge. This means that you can leave your Li-Ion powered phone switched off for a fortnight and it will still work when you pick it up again.

Until now, that is:

Sanyo is to introduce NiMh cells that can be used straight from the package. Dubbed 'eneloop', the key is dramatically reduced self-discharge: "Residual ratio after one year of non-use is 85 per cent in temperature conditions of 20 deg C" said the firm. AA capacity is 2.5Ah (2.3 Ah min.) with 1,000 cycle life.

I always thought the main bennefit of Li-Ion over NiMhs was the reduced memory effect when the battery is charged up without being discharged first?

Nice - I hope they take off.

NiMhs have no memory effect - that's NiCds.
