Makro 2.4 Ghz headphones & Makro AA charger

[Sataro]

Did not get any documentation with either wireless headphones or double AA charger...
When charging the Makro 2.4 wireless headphones or AA battery pack, does the red light turn to green when charged? Thanks...

I don't know about the charger but the headphones go from red to OFF.

The charger blinks until batteries are fully charged, then goes solid red.

Tom, thanks for the info. That was what I thought but I wanted verification. Thanks...

Thanks for the info. Wasn't sure how long I was going to have to leace them charging.

If they are the varta (sp?) Green rechargeable then the work surprisingly well!!!
I ran my ones I got with my makro racer 2 pro pack through my custom charger/tester and they all were above the stated MaH.
But I would like to recommend getting at least a set of 4 eneloops/charger combo off Amazon (~$17) and using the Panasonic charger.
The varta charger is just a timer charger from my experience and can damage the cells if put on when not dead, but I could be wrong. Getting a -∆v type charger is beat to protect batteries.
I have a lacrosse 1000 that I mostly use so I can customize everything, cycle them, and test them for how much charge they hold.
But for now the varta should work, just keep an eye on them and if they get hot (warm is OK)

The eneloops are the best rechargeables on the market and their advanced charger BQ-CC17 is the best one. The cc55 is a quick charger but can shorten the lifespan of the battery but pushing too much too fast. The cc17 is a steady 300Ma charger with the timer+ -∆v cutoff to prevent overcharging. I'd send a link but not sure about the rules here. It's a good current to ensure long life in the batteries. The cc55 pushes anywhere from 900Ma-1300ma depending on how many cells you're charging at once. That over time can hurt them. Ideally for long life you want to charge at 1/4-1/2C (1/2 being the highest for a quick charge) C= stated MaH on the battery.
So a 2000mah battery ideally charged at 500ma or 1000 max for quick charge.
When looking the cc17 will have the number but also will say "advanced"

Like I said I still use the varta cells and will continue to but to get a spare set of recommend eneloops. They have 1900-2000 MaH and are listed to accept 2100 charges.
They also make pro ones that are 2500Mah but are 50% more expensive. I just use the regular white (or colored special editions)

Sorry for the lengthy post but I like batteries and especially rechargeables.

I would like to know if the Varta charger is a timer version.

I would like to know if the Varta charger is a timer version.

There's two versions I guess. The one that comes in the racer pro pack is just an led light version and that one is a timer one.
But they also sell a more digital charger and battery set separate from the combo and it seems to have a digital screen. Not sure about that one.

[size=medium] Stefan,

Thanks for the info. Post was very informative. I will be purchasing another set of batteries & charger in the near future.

Well right now Amazon has a nice pack with the newest cc-55 Panasonic charger with 8 AA eneloops and 4 AAA batteries all for 29.xx
Killer deal. Plus it's a smart charger as well as a fast charger and it doesn't trickle after it's done. If they are sold out at that price by the time you see it, they will be back in stock for that price.

Also I stand corrected on the cc-55 charger I sent you the link for.
It does push more current in but it's still at a safe level

Does anyone know of a good AA charger that uses a 12 volt DC input ? I am currently using the Varta batteries as well as eneloops with the supplied Varta charger as it has a 12v input.
Thanks.

This is the Nitecore d2 charger. They also make a 4 battery one. This one came with the car adapter allowing it to work off of 12 volts. It uses -∆v/∆t pulse charging which is best for NiMH batteries. It also charges liIon cells which is what I originally bought it for.
But if it works with car charger cable it will work with anything.

Is there a reason it has to work in DC12v?
The Panasonic charger has an AC plug that will work all around the world and can purchase adapters for worldwide charging

Thanks for the reply !
>>>>Is there a reason it has to work in DC12v?<<<<
Just convenience, I drag a trailer into the desert to dry camp, and try to stay out 2-3 weeks at a time. I have plenty of solar power, 200 watts of panels feeding 2 Trojan T605 batteries in series. An inverter is just one more thing to bring along that can break.
Thanks Again.

OK. Then that Nitecore will work. They don't all come with the car adapter though.
That one does and comes with the car adapter and it's cheap. Seller is eastshine and it's 14.99 so you can get 2 if you need to charge 4 at a time. But that kit from eastshine comes with the cig lighter plug

Vic, I used to be able to handle getting away to dry c amp for long periods, but my blasted health issues have limited that a good deal, so I envy you and other who still can.

This thread is running under the 2.4 Gig Headphone topic so let me comment on it first. I really like my Makro 2,4 Gig Headphones and use them almost exclusively with my Racer 2, or dongle-over to the Gold Racer when needed.

Now, as for powering my Racer's and FORS series models, both the CoRe and Relic's I tote along, I DO have a Makro/Nokta Varta charger and batteries in each of my detector bags that tote my extra soils and rods and some other items. I use the rechargeable batteries from time-to-time, but not on a regular basis because rechargeables generally tend to have a shorter run-time than alkaline batteries and also seem to quit more abruptly.

My preference, for a long, long time, has been to use the Costco 'Kirkland' brand AA alkaline batteries because they are made by the makers of Duracell, and I get about equal performance at a much lower cost. At Costco they are just under $13 for 48 alkaline batteries, so that's about 27¢ each, or only $1.08 to fill any Racer or FORS series detector ... and operate a lot longer than a set of rechargeable batteries. If I don't have Kirkland batteries and there aren't any sale prices going, my next battery picks are the Duracell, then the Energizer.

But, we are now wrapping up the Christmas Holiday Season and I always keep alert for any sales on AA alkaline batteries and stock up. I use them in a shaver I keep in my truck, in several of my flashlights, my computer mouse, as well as my primary-use detectors so I like to have an ample supply on-hand.

I start each year with a 48 pack of alkaline batteries in each of my 3 Nokta detector bags as well as my plastic parts-kit tote, and I made sure I am set to start 2017 already. I still have plenty of alkaline batteries in my den battery/flashlight tote as I bought some 48 alkaline AA packs for $9.95, then they had another sale for $8.95. Combined, that bunch of batteries ran 18½¢ to 20¢ each so I will fill each of my detectors with 4-AA alkalines for 77¢ [size=small](at 19¼¢ per battery)[/size] and last longer than rechargeables w/o a concern about charger or inverter break-downs.

Just how I like to do it.

Thanks for the reply Monte. It sounds like you have a very good system for powering your detectors and accessories. I have been using the factory supplied rechargeable batteries in both my Makro Racer 2 and Whites V3i. I believe my mistake has been using Duracell alkaline batteries for backup and also using them in my other devices. I have lost 3ea 3C cell LED flashlights, 1 AA LED flashlight, 1 AAA laser pointer, & 1 Midland GMRS radio to leaking Duracell alkaline batteries. I have switched away from Duracells to Energizer Industrial alkaline and haven't had any leakage issues from them, but I am still trying to move away from alkaline batteries.

Thanks again for your reply ! I really enjoy reading your posts and appreciate the time that you take to teach and share your experiences with others !!
