For microphones that need a bit more voltage than typical NiMH 1.2 batteries give you may want to use the NiZN AA rechargeable batteries and the 9.6 volt variety or NiMH batteries. They each need a separate charger but I will add the links to these products for you so that you can see them online.
This is the charger kit that comes with a NiZN charger and 4 batteries. You can get more batteries in packs of 4 or 8 as well.
This is the Maha 9.6 volt “9 volt NiMH battery” – most “9 volt NiMH batteries” are actually 8.4 volts, and some are only 7.2 volts (Energizer brand) but for devices that need more voltage from a 9 volt rechargeable battery these are the way to go.
You need one of these Maha chargers to charge your 9.6 volt NiMH batteries
http://www.greenbatteries.com/9vnimhsmart.html - this one charges up to four batteries.
http://www.greenbatteries.com/ma10cesmchfo.html - this one charges up to ten batteries.
WE have lots of customers that use these specific batteries in their mics and I guarantee that these items will perform well in yours.

We are currently looking to purchase 1-2 battery chargers and several rechargeable batteries for use in our wireless microphones at church. We have at least two microphones that need AA’s and three that need 9V’s. My experience in the past has been poor because of the lower voltage of some rechargeable batteries so I am looking for recommendations along with prices. Thank you for your feedback.
Grace and peace,
