i think the batteries are just to keep the time/date etc in memory if the power fails. obviously, if its soldered in its not designed to be replaced. why do you need to replace it? (lots of power cuts?)

I HAVE THROWN AWAY 3 OF THESE CLOCK THIS WEEK AT £80 EACH BCOS AS THE BATTERY goes FLAT THE CLOCK LOOSES TIME.THIS IS FROM THE MANUF WHO SAY ALL IT NEEDS IS A BATTERY.

I think that you are missing something.

If you are talking about the semi industrial three or four pin plug in clocks then the on board batteries on the red faced quartz model are only intended to provide a sustaining power for a short delay of a few hours, not days or weeks.

I do hope that your clocks are not wired backwards or having the supply cut regularly.

They have a limited life of only a few years, say six max. After that the batteries can easily be replaced as a very simple task for anyone capable of soldering electronics components. Its an industry standard NiCad cell but a Li-Ion replacement is probably a better component to use.

"My Q550 timeswitch is losing time. Why?"

"The Q550 timeswitch utilizes a battery and the timing is dependant on the battery voltage. Therefore after approx 8-10 years in operation the timing varies as the battery voltages decreases. Replacing the battery would resolve the problem.
