Rechargable batteries and information
john hamiliton
Maplin are selling so called 'Hybrid' rechargable AAA 800 mAh at four for
£10.99. Whilst Argos are selling four 'ordinary rechargable' AAA 850 mAh at
£5.99 (and 1000 mAh AAA at £14.99, which seems a big jump in proportional
price for another 150 mAh ? )
In this DAB radio situation, would so called *Hybrids* be of any extra
advantage, considering they are practically twice the price of Argos?
Grateful for any advice on the latest state of play with these rechargable
batteries, and any info on where best to buy them from. Thanks.

Hybrids are only really useful in devices that have a very low power
requirement or aren't used for long periods, as they retain charge
better than conventional NiMH. ISTR Lidl was pretty cheap for no-name
NiMH last time I looked.

Or even better, 7dayshop.com are usually the cheapest. I buy their own
brand AAs and AAAs for around �4 for a pack of 4. Watch out for retailers
selling lower capacity rechargeables.

The thing I would strongly recommend is to get one of the slightly more
expensive chargers which senses and recharges individual cells. I get much
better life out of sets of (AA) batteries since I changed over to one of
them.

Hybrids are better than ordinary NiMH batteries because they provide a
slightly higher voltage for longer. As it's usually the drop off in voltage
that triggers the 'low battery' warning you may well find that a 850mAh
hybrid will be significantly better than a 1000mAh ordinary one, at least
that's what I've found with my digital camera.
As for where to buy them; Amazon has good prices (4x AAA uniross hybrio for
<�4 and free P&P )

is it's anyone's guess when they are in stock.
My local lidl's have been out of stock of them for the last 6 months
Lots of hi capacity AAA on eBay such as:

�3.28 for 8

That's what I was about to suggest. These chargers prevent over- and
under-charging by sensing the voltage of each cell while they are being
charged.

Hybrids have slightly less capacity than regular NiMH batteries but lower
self-discharge rate and hence longer shelf life. For a DAB radio that's not
used infrequently, I'd be inclined to use regular cells.

Ahem; it is also a characteristic that the voltage is higher for longer
during discharge, so they trigger the 'low battery' warning later than
standard NiMH cells.
