Powerex MH-C9000PRO Professional Charger-Analyzer

Powerex has solved all the problems I had with the previous version of this charger. It is so good that I went ahead and bought two! I also have Powerex C980 Turbo when I just want to charge up to 8 AA or AAA cells. But the C9000PRO has 3 additional modes that allow me to get a lot more use out of my batteries. The analyze and refresh setting is great for actually improving your batteries' capacity. This charger also allows you to determine the actual capacity of each battery so that you can better match the capacities in a device. I love the feature that Powerex has added to allow us to copy the settings to all slots so that you don't have to enter the same settings 4 times over for 4 cells. This one change makes it so much easier to use! This is the best battery charger yet, bar none and well worth the price given how many alkaline batteries it will save you over the years.

Powerex MH-C9000PRO released oct 2020 is the new version of the MH-C9000 which has been consistently rated as the best nimh battery charger in most online "top list". it gets this rating for good reason, its simple and lets you choose how you want to charge your batteries. unlike the previous model this updated version no longer has the "cycle" function where you can tell it to cycle your cells a given amount of times. however this isn't really required as "refresh and analyze" run multiple times could do the same. with the new version you do get a much better design, and a light that you Don't have to fiddle with buttons to turn off. what you do get are four simple modes, "Charge" - real simple put your battery in and select your charge rate from 200 milliamp to 2.0 A in 100 milliamp increments "break-in" - after inserting a cell you will have to enter the capacity of the cell. from there the charger applies a 16 hour charge .1C then a 1 hour rest a .2c discharge of the battery, a rest again followed by another .1C charge. C being = to the batteries capacity. this will overcharge the battery to its maximum, any excess being converted to heat, or hydrogen gas bleeding off through the vents. "Discharge" - a simple cycle to discharge the battery and not recharge it, just select your discharge rate. "refresh and analyze" - a very simple charge, discharge, charge cycle at the charging and discharge rate you choose and a capacity will be displayed at the end. the charger does have a 10 milliamp trickle charge while the cycles are finished, except discharge. a bit unnecessary for a low self discharge battery and a 2 hour top off charge of 100 milliamp after the charge cycle cuts off at 1.47 volts. which the cut off could be triggered by the battery temperature. for a 60 - 70 dollar charger its not bad, but the top off charge and trickle charge are not really needed with the new low self discharge batteries. its better then a timer cut off, but could use the ability to stop at the voltage drop. short of spending more then twice as much on the sky rc mc3000 or the slightly cheaper sky rc mc2600 where you can set a charging program custom to what you want, this is about as good as it gets. your only other option would be use an ardunio to build your own charger. with cheap cells being just over a buck and good ones just over 2 bucks is it really worth it when most of the time youll be charging at 500 - 1000 milliamp, I don't think so. so go ahead grab two, you know you'll use them.

Great quality and does everything it says. Follow Directions

I got this to see if I could figure out why my basic smart charger stopped charging my AAA Eneloops recently. Long story short, my Eneloops have a date code of 07-11 HH, which means I bought them sometime in 2007, and what I started running them in recently doesn't have a low-voltage shutoff so basically took the Eneloops to zero volts. As I learned recently, this kills NiMH batteries. So, I decided to use this to charge and analyze/condition my EBL AAA NiMH batteries with a nameplate rating of 1100mAh, and there's where the problems began. I bought 20 of these early last year and right from the get-go they had less runtime than my 17 year old Eneloops. When I ran them through this charger I get all sorts of whacky mAh numbers, and some batteries will sit on "Charging" at 300-400mA for four plus hours, far exceeding their rated capacity, and get really hot in the process. I don't know what charging protocol it uses, but hopefully it's not just straight ramming current into the battery. One battery I'm working with right now came back as 19mAh capacity from the "Refresh/Analyze" cycle, sat on Charge for 5 hours at 30hA before I manually pulled it, and after letting it cool I ran a Discharge cycle on it that showed 688mAh. I had 4 of the EBLs that were unused, still in the factory box, so I ran a Break-In cycle on those and that took two and a half days to complete, with final mAh tallies of 19, 594, 674. and 706 mAh. The internal programming and logic seems very inconsistent for something that cost as much as this does. 06/21/25 Revised stars up to 4 from 2. Turns out all my old Eneloops were bad, as were most of the EBLs. I figured out the Eneloops were almost 14 years old, which I didn't realize. I've been using this to try and save/recondition my various LSD NiMH batteries, including my Duracells and Energizers. So far I've been able to save many of my other batteries, or at least get them back to usability. For instance the EBL AAAs were labeled as 1100mAh, most are coming back to the 500-700mAh range. Two are duds, less than 100mAh each, and several are less than 400mAh. Out of 28 batteries originally purchased 4 years ago, I can use around 16. One thing about this charger that I dislike is the way the backlight is managed. If there are no batteries in it then the backlight can't be turned on by pushing the UP/DOWN arrows simultaneously for two seconds. If there are any batteries being charged or discharged then the buttons work to turn the backlight on or off as the instructions say. If you take the batteries out while the backlight is on then it starts blinking on and off, and the only way to stop it is to put a battery back in or unplug the unit.

Looked the most well-made charger on the market, but... 1. Fast charging my eneloop pro AA, it failed to stop even at the set capacity, became so hot the battery blistered 2. A dead cell could discharge in definitely without completing the cycle 3. After 3 months, it kept restarting in 1 min cycles amd finally couldn't power up

not sure if the charger is good or not, because I can't use it. I'm in UK and it was sent a power supply with a shaver socket. The daft thing is that the model clearly supports interchangeable heads.

Algo caro, pero es un producto muy profesional y funciona muy bien

This is by far the best charger/analyzer I’ve ever owned — even better than my Powerex MH-C9000PRO, MiBOXER C8, and TN438 units. It’s perfect for conditioning brand-new batteries, keeping stored batteries healthy, and reviving ones that have been abused by family members. I liked it so much that I bought two more almost immediately. Highly recommended for anyone serious about getting the most out of their batteries.
