Does anybody know of a cordless transmitter and receiver that doesn't eat
batteries? ......the ones I have had you couldn't keep up with the battery
replacement .....

The "Current Cost" one that I got free from e.on used a single D cell,
and I never had to replace it in the years I had it.

The OWL ones seem to last plenty long enough on their batteries -
roughly a year or so.

What model have you had trouble with and what sort of batteries?

They all tend to be very low current draw but need full voltage to have
decent display contrast and as such do not like rechargeable batteries
at all. Initial terminal voltage is already too low to work properly.

can't remember as I binned it a while back....but the rx used up alkaline
AA's in about a fortnight......just bad luck in my case as usual I pick all
the lemons probably as price is my only consideration when buying.... .....

The CC one I mentioned used a wall-wart for the display part with the
smarts in it, the battery powered bit was just the clamp-on coil and
transmitter.

I follow the same policy.

The one I have, that now sits with the batteries out, is badged
"Protectrix" and came from Wilkinsons at a very much reduced price.
Completely useless because of the battery wastage. It ran out of battery
before I had a chance to work out what the 3 grey and one green buttons
actually did.

I have this one.

Brought in around Nov 2014 and haven't yet replaced the batteries in either unit.

I have a Current Cost. I've replaced the batteries in the Tx once. I
thought it was 2 x C cells but having just opened up it up it's 2 x D
cells. I bought it in Feb 09.

The display runs off a wall wart and has no built in battery facilty.

Well if you are running a transmitter you gotta use power surely?
Be better off with one that charges up every so often.

The amount of power required for a tiny burst of data every ten seconds
or so is miniscule. An oil Watchman which sends data much less
frequently lasts many years for example on some very expensive to buy
spares deviously repackaged in copper tube AA Duracell batteries.

The transmitter on my OWL lasts a year to 18 months on a set.

I have a set provided by SSE, and the transmitter has no batteries, it
must draw its power from the line which it's clamped around, or
something.
The display can be powered either by a USB wallwart or batteries. I
don't use it much anyway, so couldn't say how long a set of batteries
lasts, but I don't think it was very long.

Ours a Watchman Alarm, uses a single CR2430 lithium battery, it's
recently complained of being flat. Several years life...

On many of them you can change the update rate to 'slow' to increase the
battery life

The sender I have is badged Green Energy Options Ltd. and also HUMM
(tm).
It uses three AA cells and they last for years. I was quite suprised.
