Review on ⚡️ Ultimate Powerex MH-C9000PRO: Unleashing the Professional Charger-Analyzer by Jessica Sanders

I have had several battery chargers over the years. They are enough to make me doubt that even though I have over a hundred batteries, using rechargeable batteries will actually save me money. I've been a long time fan of the Powerex/Maha Energy and pulled the trigger as soon as it became available. I ordered it direct from Maha Energy as they released it before Revain and Revain isn't exactly known for their "fast" shipping to Alaska. As a battery fan, I naturally wanted a fine tuned version of the popular 9000 series charger! stupid chargers. That used to be true with time-based chargers, but almost every charger in existence today must be "smart enough" to properly handle rechargeable batteries. It really boils down to there being simple chargers and then advanced chargers to help you analyze and care for your battery collection. This device works in both categories, but especially in the last category. It is the level of intelligence and overall best practice employed in this process that separates truly 'smart' chargers from 'less intelligent' ones. The reality of rechargeable batteries is that they have certain disadvantages when compared to non-rechargeable batteries. Due to their chemistry, a battery's capacity can decrease over time due to usage conditions such as long storage or very low discharge rates. They're really great if you can guarantee relatively quick and regular workouts, but not so great if you treat them the way most of us treat batteries. This is where the battery analysis and upgrade features this charger offers come into play. This charger is definitely one of the most advanced. While many truly 'smart' chargers have similar functionality, this solves many of the problems that have plagued previous generations, including problems that have even appeared in Powerex's own products. This charger is also based on the old 9000 series charger in every respect. Let's talk about the display first! On all my other "smart" chargers (Powerex, LaCrosse), text is sometimes hard to see, especially without direct lighting. The backlight and the large (1.5 x 3 inch) display easily solve this problem. I also like how they changed the orientation of the display to vertical so you don't have to be directly over the charger to see it. The status can also be easily followed from the other side of the room. The backlight can be switched on or permanently on at the touch of a button. Second, I was happy to see that they removed the "cycle" mode from the previous model, it made almost no sense. . (Losing this feature isn't a downgrade in my opinion. I prefer to make the decision based on the mAh rating, especially in the age of "pro-grade" batteries.) This device has the four main modes you need battery management . Hack, update, load and unload. The use of these modes is well described in the manual. Essentially, these four modes allow the user to restore "bad" batteries to their former glory, identify truly "bad" batteries, and generally keep your batteries operational. The biggest upgrade over the old Powerex 9000 series charger is the memory. Function. It's true, this device will remember your previous settings you used including mode and charge/discharge values for each individual slot. This is very useful as I often use this charger for a specific purpose e.g. B. for charging a battery with several batteries at the same time. If you think of this as an update to the older 9000 series, it's not the most groundbreaking step forward, but it's very, very comfortable. This particular charger delivers a small but steady charge after completing a charge cycle. The aim is to constantly "charge” the battery and ensure that it is 100% ready for use. This is a controversial issue in the rechargeable battery world, with some saying it shortens battery life. I see both sides and both make sense. This function is not an obstacle for me, as I always have the option of removing the batteries from the charger. Overall I am very happy with this charger. I really like being able to see how much power I'm adding or draining from each battery in real time. I like being able to see the current battery voltage. It's pretty clear what the charger is doing at different stages in each slot, which isn't easy to communicate. I was also very pleased to see the recommended charge/discharge rates in the manual based on total capacity, I didn't realize that was the case! Batteries are easy to insert and remove from the device due to the design. This charger will definitely improve my overall battery management practices that use a lot of rechargeable batteries. The closest charger I have is the LaCrosse BC900, which I prefer for restoring old batteries that aren't up to par. . It has very similar features, so why should I upgrade? In addition to a greatly improved display, this charger fully integrates "rest periods" into the charging and discharging cycles. These cooling phases are good for your batteries. Second, and most importantly, the LaCrosse update process will cycle the batteries until no improvement is seen, whereas this device requires you to restart the process manually if necessary. (This is important for high-end batteries that have very limited charge cycles.) Next, navigating this device compared to this device is just plain harder, I always had to remember how to access modes and such. Another benefit is that this model allows for truly independent modes for each slot, while LaCrosse treats all slots the same. This device also has well thought-out thermal properties, the batteries are very well ventilated from all sides, which prevents significant heat build-up. Finally, I love the real-time information (mAh input, voltage levels, usage time, etc.) that this device gives you, that's light years more than the LaCrosse can do. Version with 8 bays because I only want one charger. I also have a Powerex C800S when I need to charge many batteries at the same time. At least for now, there seems to be a trade-off when it comes to 4 and 8+ bay chargers. Bigger chargers just don't have as many advanced features for true battery recovery. There is simply a difference in the results you can get with normal "conditioning" versus the IEC guidelines for battery forming procedures. Some of this charger's modes (e.g. burglary) can last over 40 hours on a single battery, meaning you'll sometimes stall the charger for days. Even longer if you need to run multiple cycles to improve battery health. So maybe that's the silver lining to separating "bulk charge" and "analysis" from my overall battery strategy. Finally, a few quick tips from someone with a large battery collection. When I run my batteries through a refresh or break-in cycle, I put a label on that battery. It includes the month and year of the update and the mAh rating I get from the analyzer. This allows me to "match" batteries of similar capacity and also give me an idea of when to run the refresh cycle next. I usually try to update every 12-18 months, give or take. I'm also updating after removing the battery from extended storage that lasted over 6 months. If the battery is working below the rated value, this is a pause in the process. Nowadays, rechargeable batteries are pretty good. I have completely replaced all AA/AAA batteries with them and no longer use regular batteries. I chose Eneloops and they are incredibly stable from batch to batch, last a long time and work well even at low temperatures. I use "professional" batteries in mission critical applications (like my electronic door locks) and use standard Eneloops for everything else. I think that's all for now. I will update this review with any significant changes or disclosures. For now, in the early days of launch, I'm very happy with my decision to upgrade to this charger!
