Batteries for Wireless Microphone Systems
There are many different brands of batteries that work with Wireless microphone systems. Selecting batteries depends on how much you will be using the microphone. How long is the gig you are playing? Are you performing at a Theater and need batteries that will last 6-7 hours? After testing several different brands of rechargeable batteries and with lots of trial and error, we decided to use the Panasonic “eneloop” (see images below). These batteries worked out great for our applications.
All batteries will eventually fade away and start losing their ability to hold the same voltage as when they were brand new. The overall reliability was the main factor in staying with these batteries – they worked best for our needs. This should not be taken as an advertisement for this model battery. The information stated here comes from experience with their use.
Example of Battery Charger – Video Clip!
The charger that was used with these batteries had many features as well. This charger displayed the charge and also when the battery was not holding a charge any longer. Once this occurs, you should dispose of the battery (per the manufacturer’s recommendations) and replace it with a new one.
Rechargeable Battery Tips / Notes
- 750mAh (milli Amp hours) would be a very good starting point for wireless microphone batteries. You should not go any lower than this if you are looking for long lasting and reliability with this type of rechargeable battery.
- This certain model of battery can be recharged up to 2100 times, and the manufacturer claims that after 10 years the capacity will only go down to 70%. This is a very good specification to be aware of when researching batteries.
- Another feature about this battery is they are recyclable
Important Note:
Some wireless microphone manufacturers recommend using only 9V / AAA alkaline or lithium batteries for their wireless systems, and they do not recommend Carbon Zinc, Rechargeable NiCad, or NiMH.
Before committing to using a specific type of battery for your wireless microphone system, you should always refer to the manufacturer’s user manual to verify what battery/type they recommend using with their product – using a different battery could void the warranty.
