Product Description
The MH-C800S features eight independent slots that can charge one to eight AA or AAA batteries in any combination around one to two hours - it's like having eight chargers! The unit also incorporates a large LCD screen featuring the charging status of each battery. This new charger uses the same precision microprocessor as its professional sister model MH-C801D.
The user can choose between a soft and a fast charge mode. The soft charge delivers the highest battery life and allows 100% compatibility with older, lower capacity batteries. The fast charge allows eight batteries to be fully charged to their maximum capacity in as little as one to two hours.
The Eight Cell charger is embedded with a high-rate battery conditioner that will charge, deep-discharge and recharge batteries automatically for maximum performance. The cycle restores the batteries to their optimal performance level minimizing the memory effect. Batteries that were previously thought ready for the recycle bin can be brought back to life.
The MH-C800S can be used anywhere around the world using the included switching AC power supply, perfect for home, office and travel.

Very good but not perfect...
By D. Culley
I also own the LaCrosse BC-900 charger, and am glad that I own both; each has its own benefits.Either charger is very good because:- They charge each cell individually, rather than in pairs, resulting in the best possible charge for each one.- They offer different charging rates, so as often as you are able, you can slow-charge the batteries to ensure they last longer, but you can still quick-charge when you must.The PowerEx charger is better in that:- It handles eight cells, not just four.- A major advantage they didn't advertise, as far as I saw: it pulse-charges the batteries. Pulse-charging noticeably improves each battery's total charge capacity, in both mAh and voltage... even when you switch to another charger later on, the battery is the better for having been pulse-charged. LaCrosse doesn't do this.The PowerEx misses on these fronts:- It false-peaks a little more often than does the LaCrosse. This is where an actual voltagte reading would come in handy, because you could easily spot the false peak, and charge the battery again.- It doesn't offer charge rates below 500mA; you have only this or 1A. I like the 200mA setting the LaCrosse offers.- If a cell is deeply discharged (below .9V?), the PowerEx won't attempt to charge it. LaCrosse suffers the same problem. In such case, though, I pull the cell out and use a couple of paper clips and a charged cell... kinda like jump-starting a car... for 20 seconds, and then try putting the battery back on the charger.Overall, I'm glad I bought this charger.

Does exactly what it should do.
By dsrussell
This is a pretty large battery charger, but if you need to charge a lot of rechargeable AA or AAA batteries often, then this one will do it, and do it well. I have an outdoor walkway solar lighting system that requires 24 rechargeable AA batteries. Since I swap these out with 24 other rechargeable batteries fairly often, I really needed this product.You can charge one battery or eight batteries or any number in between, and they can be a combination of AA or AAA NiCAD or NiMH batteries -- no other type (but there is no worry about where they are placed in the charger or in what order). The Powerex gives you 3 modes of charge: Rapid, Soft and Conditioning (refresh). Its default setting is Rapid (just put in the batteries -- there is nothing further to do). If you want to Soft charge, place just one battery in and push the button on the right within 5 seconds (release the button when you see "soft charging" printed in the window), then add the rest of your batteries -- they will all Soft charge). If you want to Condition, go through the same procedure, except you push the button on the left. I don't use the Rapid mode. I use Soft mode (easier on the batteries and I think this should have been the default mode) and no doubt I will condition these batteries if they begin to show signs of not performing as long as they should.How long does it take to charge your batteries? The manual states 1 to 2 hours on Rapid mode, 2 to 4 on Soft mode, and up to 16 hours on Conditioning mode. Time is also dependent upon the mAh of your batteries. It will take a lot longer to charge 2700mAh batteries than it would to charge 600mAh batteries (for batteries under 800mAh always use Soft mode, never Rapid mode).Unlike the La Cross BC-900U (which I also own), this unit is very simple to operate (but costs more). The La Cross has more flexibility (allows wider range of charge rates starting at 200mA, not just a Rapid 1.0A (1,000mA) charge rate or a Soft 0.5A (500mA) charge rate, but it's more complex and more restrictive to use). Between the two, I prefer the Powerex MH-C800S (and the ability to charge twice the batteries). Plus, the La Cross display bit the dust after a month of use and needs repair already.Batteries fit tightly in the Powerex and are fairly difficult to remove (not so on my La Cross), and the screen fonts are so tiny that they are next to impossible to read (depending upon your vision). Luckily, the screen displays 8 large battery icons to let you know what is happening to each battery during the charge and when they are done. The batteries do get very warm right after being charged (they cool quickly though). I would not recommend using this and going to bed. It's also a good idea to place this on a non-flammable surface. But I think that would be the case for any battery charger. Better to be safe than sorry.All-in-all, a quick convenient way to charge a lot of batteries with a unit that is very simple to operate. Between 1 and 10, I give the Powerex an 8. It's far too early to tell how long this charger will last (or if I'll have problems like I did with the La Cross), but hopefully I'll get many years of usage of it.

Great charger, crappy instructions
By Kim Mcannally
I love this charger, but the instructions are horrible.The charger uses your choice of 500 mAH or 1000 mAH charging rate.The default rate is "rapid mode" which is the 1000 mAH rate.Personally I would prefer the default mode to be the slower charge rate.The instructions don't tell you that the "condition" mode is actually done using the higher maH charge of 1000 mAH.I had at least two AAA batteries vent while conditioning them since I thought the condition mode would be done using the lower 500 mAH charge rate.You can actually condition batteries at the lower 500 mAH rate by inserting one battery and pressing BOTH the condition and soft charge buttons. Highly recommended for AAA that are rated under 1000 mAH to keep from frying them with the higher charge rate.It would be really nice if the instructions told you about this option.
