Powerex MH-C9000PRO Professional Charger-Analyzer

I have been using a La Cross charger for years with my Eneloop black batteries. Some of my batteries were not performing so well after 8-10 years. The Powerex charger helped me cull out the bad ones and see how well some of the old ones are actually holding up. I have done many Refresh-Analyze cycles on my old and new batteries. I found the capacity readings much better on this charger than on my old one. It is not the easiest charger to use as you have to enter the charge and discharge rate everytime, but I think it is the best for your batteries. I also highly recommend the black Eneloop batteries, I bought another brand with high advertised capacity only to find the 8 year old eneloops had more capacity than the new ELB's which have about 70-80% of their advertised capacity. Great Charger!

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.

You should get this charger just for the manual. You'll learn something. Nobody knows "rechargeable batteries" like Powerex, nobody.Although more expensive than the alternatives, this charger will be a big, big, huge money saver in the long run. Plus save the environment.After doing lots of painstaking research, looking at performance charts, and having used Powerex 9v products for years, I pretty much will not use anything but Powerex.Any equipment that requires flawless battery operation with minimum risk of battery failure absolutely needs Powerex batteries and a Pro charger such as this. Any critical battery-operated equipment absolutely must run on Powerex to have consistent performance while avoiding failure in my book.Thanks a ton, Powerex, for sticking to your guns and not cheaping out on the builds! You guys are my heroes.

Bought this as a replacement for an earlier version of this charger by the same manufacturer. I've used it so much the slots were wearing out. What I like about the new one is the display goes to low power with no backlight after a few seco ds which saves power. What I don't like is the earlier version had a flip-out metal stand which allowed the unit to cool more effectively. My biggest issue is rather than the display giving a "high" message for damaged or defective batteries, it allows them (and the unit) to overheat to the point where I'm afraid they might melt, catch on fire or at least damage what they are sitting on.

We've switched ALL our AA and AAA devices to Panasonic Eneloop batteries over the last several years (flashlights, remotes, keyboard, walkie talkies, you name it if it uses AA/AAAs we use rechargeables in it) so we charge and recharge a LOT, this is great to be able to analyze and detect when a specific battery in a group is going bad so you can just replace that one instead of guessing. Also refreshes batteries that haven't been used in a while and breaks in new batteries to the proper charge level. This was an upgrade from a basic Powerex 4 battery charger I got about 10 years ago that still works fine, but I am glad to have the extra features now we use so many rechargeables.

a few things.1-whos the clown who thought having the display flat to the front is fine? are you putting it on a shelf thats eye height? no, so why not angle the screen up ffs?2- you have so much space on the device yet such small buttons. make the buttons bigger ffs!3-not a reliable brand. I bought 2x 808 together. 1 failed within 3 months of use. the lcd is horrific and illegible and they have this terrible proprietray connector that easily shorts out because you can easily insert it wrong. its not a 1 way connector. their design ruined the charger and no I didnt get any support from powerex.I prefer to have backlit on always. you can set it to be on always by pressing both volum buttons together. but it doesnt stop flashing the light. it came used. you can tell.this brand is a joke. im not happy. I made a review ill post on YT and different forums so others can see. I also added the defective 808 charger.
