• Instead of a battery LesLee® uses a custom made supercapacitor with an ultralong life span. The minimal recharge cycle count on the data sheet promises 10.000 charges, but in real life you can reach 3-5 times that. So, Pickup LesLee® is maintenance free for some 50-100 years until the supercapacitor would need to be renewed. I can only guess at this point in time, but probably the speed pot will need to be replaced before the supercapacitor is due.
• LesLee® is charged with the included charging cable and a 9V battery via the regular output jack of your guitar.
If you connect a brand new 9V battery to the cable it will be good for many hundreds of charges, especially if it's an alkaline or a lithium type battery. But even a used 9V battery that doesn't work sufficiently in other devices anymore, can be used to charge LesLee for many more times.
• A regular charge is done in 10 seconds (90% full) and provides about 8 hours of effect time and about one week of stand-by time. That's comfortably more than enough for regular use. Recommended is doing a charge (10 sec) before every session or show.
• If ever the charge is depleted below operating voltage, the LesLee function will stop and your guitar will output both pickups simultaneously. That is when you know it's time for a recharge.
