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 99 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. so go ahead grab two, you know you'll use them.
