I'm irredeemably clueless about electrical things (amps/watts/volts 'n'
all that) -- sorry.


Sooooo: I have a John Lewis portable digital radio (£30.00). The sound
is *great*, and it has a nice simple unpretentious style about it
(looks-wise and functionality-wise).

However I can't get it to work portably: my batteries won't power it.
On checking the manual again, I find it requires 4x 1.5V AAs. (On
checking the batteries) I find I've been using rechargeable 1.2V
(2500mAh) NiMH AAs (which I suppose are quite old by now).

Sooooo: I've decided I need to buy some new batteries. Before I go
looking for rechargeables that will give me 1.5V, are there any *types*
that I should be looking out for? NiMH was all the rage when I last
bought rechargeables, but I suspect there are all sorts of new types
about these days.

Any advice gratefully received,

Thanks
John
