i am being driven mad by our electronic door lock which takes 4x AA batteries. it seems to be draining the batteries and when the solenoid activates it seems to drag the voltage low and the unit resets itself.
I'm after some decent rechargable AA batteries that dont cost the earth like enrloops or maybe a 6volt lithium pack that will fit in the space of 4xAA batteries??
( i have also thought about adding a power cap to try and stop the voltage brown outs)
any ideas?
