I recently got a Redsun RP2100, the users view of which I previously posted
on this group.
It has the facility to use rechargeable batteries, something of which I know
nothing about.
It will charge these batteries for twelve hours.
I want to use "D" cells but don't know which rechargeables to buy.
My local store can order me NiCad's or NiMH - I don't know anything about
that.
What's the difference?

Also there are different numbers like 1500 or 2500 which seems to mean how
long they hold the charge.
I would be grateful for advice from you highly knowledgeable fella's as to
what I should buy.
As they seem to be very expensive, perhaps I should just stick to ordinary
batteries and forget about the rechargeables?

I got a set of Energizer "D" NiMH batteries the first day I got my 2100.
They're only the 2500 mah type but they seem to last for a long time.
In retrospect I could have been better off with AAs as there is only a
little more capacity and they cost about twice as much. Also I have a
AA-AAA charger
but only a NiCad charger for the other sizes. The radio charges the batteries
OK I guess but never indicates more than 2 out of three bars on the
battery level meter. On the bright side, the radio rocks! My Sangean,
Halicrafters and Zenith are no longer used.
