Hi,

My EP3000 CH/HW controller's standby battery is knackered.

IIRC is used to maintain program for several hours in the event of power
outage. Today it lasts no longer than a few minutes. Very annoying.

Anyone out there ever attempted to repair/replace the battery? Is it easy?

I'm sorely tempted to buy a brand new Honeywell ST6400C (Potterton
successor).

Thoughts/comments?

Yes - I've done it on my Honeywell. Maplin stocked the correct battery
pack, but this was some years ago.

This might give you a guide.

Or RS, CPC, etc.

Piece of ****

4.6v NiMH oval battery

about 3 quid from CPC, I presume Maplins also sell them

I presume you know how to get the programmer off the backplate

I've wondered about whether NiMH is a suitable replacement for NiCad in
this situation?


I gave up wondering a couple of thousand battery replacements ago

Thanks,


Just got back from MAPLINS. Job done. First use of my solder sucker this
side of the millennium.

MAPLIN man said I risked catastrophy if I replace NiCad with NiMH. Let's
see!

I can assure you, there's no problem

What sort of catastrophe do they expect ?

I replace loads of them for service companies who send me non
functioning ones to repair

What do you need a solder sucker for ? The battery just pops out of the
back of the programmer

I can assure you it was soldered in on my one. Had to dismantle programmer
to component PCB's!

Certainly was on my Honeywell too. Most of these cell packs come with PCB
mounting tags. Spring contacts would be a source of trouble on something
with a life like this.

One of mine had a socket arrangement like a pp3. It wasn't 9volt, and I
couldn't get a replacement anywhere. As the mains is reliable it hasn't
bothered us, but inhibits alterations to the ring it is on.

Are you sure it is a re-chargeable type? I had an ancient Acorn computer
where the backup was simply two zinc carbon AA cells. And they lasted as
long as a rechargeable. About 7 years.

Strange, every one I've ever seen is held in between sprung electrodes

Maybe one of the springs has disintegrated in the past and it's been

On Mon, 11 Jul 2005 19:58:46 +0100,it is alleged that
spake thusly in uk.d-i-y:

[snip]

Just re-checked the battery, It's larger tags than a pp3, one each end. It's
cylindrical made up of 8 cells, it's 33mm dia and 70 mm long.


On end it says VARTA 250DK

On the side it says Do not incinerate D86
Tel 0460 73366

Controller is a Sunvic.

The Varta 250DK is 1.2 volt, 250mAh rechargeable NiCd, if (as you say)
it's 8 cells, that would mean 9.6 volt at 250mAh. These batteries or
their replacements *seem* to be available still. (I got the above
information by googling for Varta 250DK).

Yes, but they're of a completely different shell construction

Yes they are, the plating comes off, they corrode and sometimes they
break

What make / model ?

I traced out the circuit. It's definitely intended for a rechargable battery.

Hmm ... not seen one of those in a programmer before, it must be a bit
old to require such a voltage

If you need a replacement battery, AllBatteries are an agent for varta

Nope, just know enough German to grub through the German results on
google...It was there in Jaopanese too but that's generally beyond me ;-)

(Although I did get an old service manual from a Japanese site when just
about every other site had let it drop... numbers are often left in 'roman')
