Izen Ears Posted October 21, 2021 Report Share Posted October 21, 2021 New show wants us to use all rechargeable batteries, and I’m just wondering which AA people like for their transmitters. They are recommending one of these three, and I am wondering which is the best: Sanyo Eneloop 1900 mAH Powerex 2700mAH Ansmann NiMH 2850 mAH Obviously the Ansmann ones look the best, but are they? The last time I messed with these was about 12 years ago, and they lasted about two hours. Thanks! Dan (Apologies if someone has already talked about this I am a terrible searcher!)

Johnny Karlsson Posted October 21, 2021 Report Share Posted October 21, 2021 I had good results with the IKEA Ladda 2450, but according to others, they have changed them recently and supposed to not be as good anymore (?) I can’t confirm or deny that, since I haven’t tried the new ones myself. Currently using Eneloop Pro 2500mah with good results. - Single battery transmitter (SMV) runs for over 4h, but have not tested running it off the rails to get actual runtime yet. - Dual battery (SMQV) ran for about 8h 30min last time I did a full test.

henrimic Posted October 21, 2021 Report Share Posted October 21, 2021 From my personal experience, The main difference between the Eneloop and the Ansmann is the way they keep the charge. If you charge fully both batteries and store them for a week, the Ansmann's will be partially discharged, the Eneloop less. I personnaly use the Ikea Ladda 2450 mAh that seems to be rebranded Eneloop's. Quote Link to comment Share on other sites More sharing options...

Izen Ears Posted October 21, 2021 Author Report Share Posted October 21, 2021 Awesome thanks fellas! The Eneloop 2500s seem like a good start. 9 minutes ago, henrimic said: From my personal experience, The main difference between the Eneloop and the Ansmann is the way they keep the charge.

We will be able to cook them and then throw them directly in a transmitter, so the issue of “storage voltage drop” (?) shouldn’t be that big a deal.

Philip Perkins Posted October 21, 2021 Report Share Posted October 21, 2021 Eneloops have been great--even batteries much used and several years old will still work all day in devices like G3s. Quote Link to comment Share on other sites More sharing options...

Oh dude thank you so much, this is exactly the information I was seeking. I will forget those and just go with the Eneloop 2500s. Thanks JW Sound!!

Valentine Posted October 21, 2021 Report Share Posted October 21, 2021 The black and orange eneloop 2500 is great. After about 3 or 4 years mine are all starting to go bad but they've had a good long life. Before those I had the powerex ones, they were great but seemed to become unusable sooner. Maybe in a year or so. Quote Link to comment Share on other sites More sharing options...

I can’t confirm or deny that, since I haven’t tried the new ones myself. I was in the same boat as you a couple weeks ago. I've been using IKEA Ladda 2450 "white" batteries for 4-5 years but they were starting to get old and less reliable. Decided to give the new "grey" Ladda's a shot (bought four dozen of them). Still say Made In Japan on the boxes. Used them on a gig and they worked fine / normal? Still need to do long term testing but so far so good...

RunAndGun Posted October 21, 2021 Report Share Posted October 21, 2021 I bought the new iPower Max AA 1.5V 2600mWh Li-po’s and they seem to be good, until they aren’t. Meaning the battery meter on my Lectro’s don’t work with them(properly) and there is zero warning of the battery dying. The transmitter is there and the next second it’s gone/off. I can put hot batteries in and the Lectro meter will show 1/4-1/2 down in a matter of minutes sometimes, even though the battery keeps going for hours. But one of my audio guys has said he’s never had rechargeable’s of any kind work properly with Lectro Rx battery meters. He just sets a timer and changes them every X hours. Also said he’s considering going back to throw-away Li’s. I hope I didn’t waste hundreds of dollars on rechargeable’s…. 1 hour ago, Johnny Karlsson said: I had good results with the IKEA Ladda 2450, but according to others, they have changed them recently and supposed to not be as good anymore (?)

Izen Ears Posted October 21, 2021 Author Report Share Posted October 21, 2021 So once again thank you everyone for your awesome and quick replies! I have decided to go with the Panasonic Eneloop Pro 2500s with their fancy new BQ-CC65 chargers. Dan Izen Quote Link to comment Share on other sites More sharing options...
DanieldH Posted October 21, 2021 Report Share Posted October 21, 2021 White Ladda had the best price point for me. Afaik higher capacity relates to less charging cycles. My question regarding a battery is, will it hold till lunch/hole day, or do I need to swap in between. Quote Link to comment Share on other sites More sharing options...
LarryF Posted October 21, 2021 Report Share Posted October 21, 2021 Here's a test on some AA rechargeables after a year of use in solar lights, i.e., many charges and discharges. https://www.bing.com/videos/search?q=projectfarm+rechargeable+AA+Batteries&&view=detail&mid=12C4897AB10FFD02F03712C4897AB10FFD02F037&&FORM=VRDGAR&ru=%2Fvideos%2Fsearch%3Fq%3Dprojectfarm%2Brechargeable%2BAA%2BBatteries%26go%3DSearch%26qs%3Dds%26form%3DQBVDMH This projectfarm guy tests a little bit of everything, generally very thoroughly. He doesn't test the Eneloop black, which I found to be the best 5 years ago. But that was 5 years ago. Don't trust the ratings of off brand batteries; the measurements are dreamed up by the marketing depart after being threatend with unemployment if sales don't go up.

A shame as I was hoping to try some Pukemark NiMH AA's off Amazon (https://slate.com/technology/2020/10/amazon-brand-names-pukemark-demonlick-china.html) Speaking of Amazon, I'd avoid buying even name brand stuff off there as they just throw all the fakes into the same bins as the knockoffs and I'm sure cheap knock off suppliers love selling cheap NiMH labeled as Panasonic for the big bucks.

It is absolutely impossible to measure the voltage of a NiMh battery and derive its state of charge. Do as your audio guy suggested; fully charge the NiMh and then use the timer to determine how much time expended and/or left. The power light color is absolutely meaningless for NiMh be it green, red or purple, except to tell you that the transmitter is on.

osa Posted October 21, 2021 Report Share Posted October 21, 2021 I too use the black eneloop pro’s with great success for many years. i keep them numbered and rotate them, they hold charge really well over a few weeks at least with slight dips. There definitely is a charging rythm that is device specific i.e. trx’s n rx200’s i charge the morning of whereas erx’s and sennheiser g2’s i can let them set for weeks and still make it thru a full day. So i have color coded battery cases to split these up, and newest batteries with highest numbers stay specifically for the higher draw devices mentioned above. I do believe the chargers like the 16 bank titanium chargers help in the long run with proper charging and periodic refreshing vs the lesser quality 4 bank chargers sold it kits Quote Link to comment Share on other sites More sharing options...

This is an interesting test, but what bothers me a bit is, that he compares values of single samples of each product. Whenever I bought some Ladda, I've put them in a C9000 and an ISDT N-Series (empty bays in between), energy density and inherent resistance already vary quite a bit within the same pack. Obviously, it would rise the price and/or time for such tests a lot, but it'd be more fair and convincing to compare means and variations of different products.

You are right, out of the charger, there is not so much difference. The duration between 2500 and 2850 mAh is marginal. And it's not scientific by any means, but I feel like the Eneloops last longer. After two years, I had many failures with the Ansmann. Quote Link to comment Share on other sites More sharing options...

These are actually lithium batteries, not NiMH and I have the receivers set to lithium batts. Quote Link to comment Share on other sites More sharing options...
drpro Posted October 22, 2021 Report Share Posted October 22, 2021 Also storing your batteries with the proper crystal can extend their life. Blue or green seem best. Back to the Jack Daniels Quote Link to comment Share on other sites More sharing options...

These are actually lithium batteries, not NiMH and I have the receivers set to lithium batts. My error in reading too fast. Those lithium AA batteries are even worse about charge detection. The internal LiPo battery in the AA's is running at 3.7 to 3.2 (?) Volts and an internal power supply knocks the voltage down to a regulated 1.5 Volts or thereabout until the internal battery dies. The regulator then shuts down quickly to protect the LiPo. Treat them the same as NiMh; only use the timer in the unit.
