PowerexMH-C9000PRO Professional Charger-Analyzer

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.

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!

This is a nice smart-charger with a lot of display features, and it works as advertised. Well built.My opinion is that the controls/buttons/features are not entirely obvious and the time-lag between settings is a bit odd. You can get used to it, but the controls always require a double-check to see if settings are right.

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.

I've been using Maha Energy products for many years. I've had an older Maha 4-slot charger for over 10 years and it still works great. The MH-C9000Pro is an excellent tool for charging and reconditioning AA and AAA NiCad and NiMH batteries. The backlit display is clearly visible and is easy to read from several feet away. The backlight can be turned on/off as desired. The unit is easy to use, but does require carefully following the directions the first time. It's not difficult to use, just not intuitive. Charge and discharge rates can be selected for each or all of the slots. However, it still requires that the mode and rates are confirmed as each battery is inserted. The flexibility adds some complexity, and it is not plug and play as my simple old charger is. Batteries need to be inserted one at a time after powering it. The advantage of this analyzer is that it reports the condition of each battery as it goes through a charge or discharge cycle. You know exactly the capacity that each cell has after a complete charge-discharge-recharge cycle. It's interesting to see the variations between brands and individual batteries of the same type. My white Eneloops - now several years old - had the most consistent milliamp hour values that were nearly the same as marked on the label. The Black Eneloop Pro, Kodak, RayOVac, Thunderbolt, and GE/Sanyo batteries showed significant variation and most were below the marked capacity. The Eneloop Pro and Kodak AA batteries improved to nearly full capacity after a refresh cycle. You will get to know exactly which batteries in your collection will provide the best service. After using this for a week I'm very satisfied and recommend it for those who want the most performance from their AA and AAA rechargeable batteries. The only downside is that the unit does not support Lithium batteries. Maybe the next version will support the newer battery technology.
