ok, i am ordering from the same place and getting the carry bag, why not. thanks again for all your research and time devoted. i did learn a lot as well. yes, this could be a separate hobby. where are you getting your eloops?

amazon works. we are going to have $100 in this by the time we get the batteries. oh well, cant take it with you unless you are Egyptian royalty.

Meh...I say around $85-90 depending on how many batteries you get. I plan on buying 12 AA Eneloops. So yeah, I'll probably be more towards the $90.
But hey, that's why they invented overtime!
$90 or $100, no matter for such a wonderful hobby. battery chargers is the ultimate hobby. we prob talk more when we each get ours and try to fig the damn thing out. lol
The nice thing about the 9000 is that you can just put the cells in, walk away, and let it use the defaults which it will do after about 10 seconds. Then later on, you see if you want to override the default or do custom things.
Not in the manual - while using the *discharge* function to determine cell capacity, (or an automated break-in etc) is great for proving or grouping cells in a pack together, the 9000 will also show you an internal-resistance value.
But you have to know what to look for when it comes to internal resistance:
Put a cell in the charger. It will do a quick check, and the VERY FIRST value you see is NOT voltage. It is the IR, and it will only be shown once. Here is a quick chart for the resistance:
1.5 - brand new cells - high quality
1.8 - middle aged - ok, but getting a tad tired
2.0 + quickly heading for retirement - turning into a resistor
I do this IR check one cell at a time just so I don't actually miss the quick initial display.
It actually takes TWO hours after the "done" indicator activates to have a truly fully charged cell. It applies 60ma per hour for two hours, and then falls back to a true trickle of only 10ma. This is done on purpose for overall cell health. You may want to keep this in mind when doing manual capacity discharge measurements from a full cell.
Charging in the radio - I actually DO that but only on a very limited basis! Such as a weekend trip, and with cells that have been charged by the 9000 first.
Reason being is that even with quality cells, they are not recharged individually in the radio, and eventually go out of balance being charged in series. Eventually, the bad balance means one cell will totally overcharge waiting for the slowpoke to catch up. Bad news, especially if you have a cell with high resistance.
Anyway, the 9000 is about the only one that shows an internal resistance measurement, and for us true geeks something we keep track of during a cells lifetime.

I found Eneloops in a surprising place, unfortunately they are not in the stores. The last 3 sets of the Pros I got from them online.

Great feedback!
I will definitely make note of the IR reading option when I get my C9000.
Thanks for the info!

The 4 pack Pros are right at what Amazon is asking for, but it ends there.
The 2100 cycles are way high. Amazon is asking for $19.99 for an 8 pack, Target wants $26.99. Same goes for the 8 pack Pros, Amazon asks for $30.55, Target wants $46.99. Even the 4 pack 2100 cycles are way high at Target....Amazon $12.99....Target $19.99.
You might want to start ordering from Amazon.

When I got my Pros they were with free shipping, they were actually cheaper then Amazon at the time. I wont need to order any for probably a couple years as I already have enough.

In that case you were well served, as Amazon usually requires orders to be $35 or more before free shipping kicks in.

Pulled the trigger on the Maha Powerex Wizard One MH C9000 today!
Thanks for all the feedback guys!
Thanks for all the feedback guys!
post the link and i will order same from same company. might as well give them more business. thanks for all the work and research you undertook.

I've had the Maha C9000 for years and love it
Only mod I've done, is reduced the brightness of the white LED's that illuminate the display.
The thing was so damned bright it hurt my eyes and lit the whole room up when operating

Are you the Youtube guy that has the light mod video?

No. I wasn't even aware there was a youtube video of the Maha. I will have to go hunting now.
Thanks
Edit - Found it.. Nice use of the pot to adjust the brightness. I simply used a fixed resistor in mine.
I've had both La Crosse BC 1000 and 700. Both sustained heat warp damage on the board. One of the units bay stopped working and one would only charge at the lowest setting. Past couple years have used the OPUS BT C2000. So far so good. Two sets of AA 4 to 5 days a week. Energizer used to have a charger that had a small fan in under the batteries. This is a feature I would like to see on these higher-end chargers.

Most of the reviews I was watching on youtube were around 2013. One bad issue I see is the sparking connector while attaching the DC cable to the unit. That is downright concerning. The bluetooth with app is cool beans. Hopefully, they will fix those issues for future releases. Thanks for the info.

Rumor has it SkyRc is releasing an MC3000 model soon. There is a thread about it over on CP.
Agree on that bluetooth app.... If Maha ever came out with something similar, they would pull in some serious coin.
