Where can I buy 1.2V 40mAh Ni-MH batteries?

The unit will recharge them itself - I suspect they are only used to retain your settings and the clock when it isn't plugged in or there is a power cut.

The batteries sold on cards in pound shops are not rechargeable and apart from the polarity possibly being wrong they will probably leak if put in to replace an NiMh cell.

Your original link showed the timers at 3 for < £15. Is it worth paying £3.66 for a replacement battery for one?

Just a thought, as this is a rechargable cell have you tried plugging the timer in overnight to see if it charges?

If it's a mains plug-in timer, surely the unit will automatically charge it?

Thank you both. I had left them plugged in for a couple of hours with no joy, but I'll try leaving them in overnight.

Not only on those occasions, but also when the timer is........off!
