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.
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).
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 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.
That is great information. I had always wondered why rechargeable batteries always look lower in power. Thanks Bob
Extremely helpful and informative. Thank you!
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.
Excelent video just what I was looking for.
very illuminating, sir. i'm all charged up after that discourse. :)
There is a 1.5volts AA rechargeable batteries...
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
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.
What is a good price for microphones on a budget sure microphones out of the price I have samsons wire mic and Samson wireless needs 4
Does the rechargeable battery affect sound quality in microphones or 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.
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.
My celection 400w monitor are not tune properly because of passive network. Pls suggest me network for monitoring.
Plsease tell me solution sir
Overall what would y’all recommend and what do y’all use?
