Rechargeable batteries for wireless gear (mics, transceivers)

- Looking at various AA batteries (Alkaline, Nickel-metal Hydride, Lithium ion).
Batteries are rarely brought up in audio discussions. However, with many wireless mics and in-ear monitors available, it's important to know how rechargeable batteries function.
Using AA batteries in wireless mics, wireless in-ear monitors, or even for a wireless instrument... can be very expensive with continuously replacing batteries. Rechargeable batteries are great, however, it's important to understand how/why AA rechargeable batteries always seem to be "low on power".
This video is part of the "Behind the Scenes" series, which was started when Covid-19 forced event cancellations.
Thank you for this very informative video, and as a techie, it was not boring at all! I just wrote a proposal for my church to switch from AA single-use alkaline batteries to rechargeable Eneloop batteries for our cordless mics, and have been doing a bit more research on actual usage. Your video will help me to be prepared to answer the question about whether the differing voltage will be an issue. Your explanation is easy to understand and quite helpful.
Thank you for the kind words! Good luck with the proposal.
That is great information. I had always wondered why rechargeable batteries always look lower in power. Thanks Bob
None of the content on this channel is boring to me. As a solo performer who does his own sound, I'm always looking at learning how to do live sound better. This channel is a great resource!
Thank you for the comment.
Love the disclaimer at rhe beginning. Automatically subscribed.
Thanks for subbing!
Mention "per cell" because most use 2 so they use ~2.5v to 3.3v. Nominally 1.25v to 1.65v per cell. All the mics/transmitters will dropout long before the batteries are classified as flat by the battery manufactures. At least the rechargeables can be re-used vs alkaline batteries are thrown away. Capacity depends on current drawn, temperature & dropout voltage (both vary per device).
Extremely helpful and informative. Thank you!
very illuminating, sir. i'm all charged up after that discourse. :)
Yes! Figured this would get you charged up!
Excelent video just what I was looking for.
Glad it was helpful!
Take off batteries before store microphones is a good practice. Otherwise it's damaged microphones connectors as well as circuit with acid liquid. Thanks for recall me this important point.
You can also use lithium batteries like Znter. They are stable at 1.5v, but also suddenly die as Ni-Mh till you charge them again
There is a 1.5volts AA rechargeable batteries...
Sometime we goes with so much technical but it's not gives result in operating live sound. For ex equalizer. We alway try to cut frequency but sometimes I need to boost lower end 50 to 150 hz .also 1Khz to 4Khz are disturbing hums.
Does the rechargeable battery affect sound quality in microphones or iem?
Rechargeable batteries will not affect the sound quality in microphones nor IEM.
Is there an option in the menu to select the type of battery? Most Zoom audio gear give you the option the select the type of battery for more accurate monitoring. I have a Zoom FP-1 that takes two aaa batteries and shows up full when I select NiMH batteries and use my 1.2v NiMH rechargeable batteries. I also have Sennheiser 3G wireless kits. Specs show the voltage is 2.4v DC. I think there is an internal voltage regulator that drops it down to 2.4v when you put into two 1.5v batteries, which would give you 3v.
There's no menu option for selecting the battery chemistry. It's good to see the Zoom gear provides that option. At some point (hopefully in the near future), wireless mics (and any wireless gear) will be able to automatically detect which type of battery is installed. Many battery chargers currently (that can do multiple chemistry) automatically detect what is installed and charges the battery accordingly. Hopefully all mics will be able to auto-detect what is installed.
Well, if that's the case I want to see in comparison how long these two type of batteries last? According to your graph or chart, looks like the rechargeable batteries last (however as the bar indicated battery we think the non-recharge die faster since it short 1 bar) similar or longer but I want to see in action like maybe put the batteries in each as showed here but turn it ON and see which batteries out performs the other.
I'm looking for AA batteries for our wireless microphones. After the oem batteries ran out, I bought non-chargeable batteries and they don't seem to last long as the OEM even bought the most expensive brand. The most was like 4-5 hours of used ON all the times. If I compared similar used with the oem batteries, I used the wireless microphones 1-3 hours (turn on all the times) each time and 1-2 days a week. I was able to get it over a month before batteries ran out. With the batteries bought from the store only last week week.
The alkaline batteries (what most companies place in their packaging) on average, do not last as long as the NiMH. However, a battery's longevity is also dependent on the mAh (millamp hour) rating. The higher the rating (i.e 2800 mAh) the better.. as compared to a 1000 mAh battery. Also involved, is the amount of power the device consumes. Some wireless mics are considered high-power consumption devices, which Alkaline batteries will not work well for. Other wireless mics are not high-power consumption, which could mean Alkaline batteries would do better in them.
In our experiences and usage, NiMH batteries work very well with out wireless mics (a lot better than Alkaline). For the best performance and longevity, try Lithium-ion batteries. Most Lithium batteries are one time use and can be very expensive; however, they can last a long time and are designed for high-power consumption devices. From reading the other posts in this video, looks like there are rechargeable Lithium-Ion batteries now available. Try to avoid using Alkaline batteries in wireless gear.
My celection 400w monitor are not tune properly because of passive network. Pls suggest me network for monitoring.
Also I having srx 725 which network are damage.
Network monitoring of equipment is most always handled by the vendor of the equipment. Therefore, we are unable to suggest network monitoring.
For your questions (including your other posts), I recommend you join and audio forum. There are a lot of very smart people on the various forums that can answer your questions a lot better than we can. It's difficult to discuss audio related issues on this (RUclips) type of social media.
Plsease tell me solution sir

Overall what would y’all recommend and what do y’all use?
We use EBL (2800 mAh) and Ansmann (1900 mAh). The higher the mAh, the better for high-power consumption devices. I think most any NiMH battery would be good, just make sure the mAh is high enough for the device. The EBL batteries we use are good, but I'm not sure if they are actually a 2800 mAh battery.
