I have been pondering this question about metal detectors. Some use 9 volt alkaline and others use as many as (8) 1.5 volt batteries, I know you can get rechargeable batteries and a charger but I wonder why they have not incorporated an on-board charging system? where you could recharge the batteries and not have to worry about a separate charging station. You would still be able to use the one time use batteries or rechargeable. I use a digital camera where you can just plug in a charger or use one tine use batteries so why not metal detectors with the same option? maybe the do and I just missed it in reading the specs of different detectors.
