How long can I mix with Mobile DJ with the same 2 batteries?

Battery lifetime depends on your battery model
- alkaline batteries capacity is the highest (up to 7500 mAh)
- carbon zinc batteries capacity is lower than alkaline
- rechargeable batteries have the smallest capacity (up to 3000/4000 mAH per charge, but you can recharge them).

Mobile DJ consumes over 300mA with LCD backlight on, but not much as soon as the LCD switches off.

Mobile DJ should provide continuous mixing for
- 15 to 25 hours with 2 fresh rechargeable batteries (akkus)
- 30 to 50 hours with 2 good alkaline batteries.
It may be shorter with old batteries and longer with excellent batteries.
