    I have a relatively cheep LCD clock in the kids room (Grow Egg Clock) that is supplied with a ac/dc adaptor, 8V 500mA. As the little moster keeps playing with it I'd like to put it on a shelf but there's no sockets near by. Was considering one of those 9V battery enclosures with the correct...

    Can anyone point me in the direction of some Aquion battery stacks? I think there are some sitting in a warehouse somewhere after the company went bust two years ago but it is hard to find out where they might be. Thanks all.....

    According to the manufacturer Marlec, recharegable batteries are not recommended with an iBoost sender. Can anyone explain why please? My non rechargeables are now flat and the only spares I have currently are rechargeable batteries. Are they ok to use temporarily?

The old batteries were connected in serial (plus to minus) but if I try to connect...
