The Thomann MBA120W MKII handheld microphone uses LR6 AA (1.5 V) batteries or rechargeable Ni-MH batteries. To recharge it, remove the rechargeable Ni-MH batteries from the microphone and charge them using an external battery charger, as the microphone itself does not have built-in charging capability.
