#1563: SwitCharge

It seems that I have been following the wrong advice about laptop (or cellphone) battery preservation.

It’s better for them to be repeatedly slightly discharged and then recharged.

I tend to a) drain the battery completely before doing a recharge and b) run my laptop plugged in, whenever a power socket is available.

Today’s invention is therefore a timer which can be attached to a laptop (or phone) power cord which can be plugged into a machine all the time it’s available but which only passes current after a 10% discharge has occurred.
