Best NiMH Charger I Have Ever Seen - Great Price
La Crosse Technology BC-9009 AlphaPower Battery Charger
Customer Reviewer and Rating: A. Davis - 5 Stars
This is a super smart charger with the all important negative delta V cutoff that prevents frying your batteries. It also has selectable charge rates. If you have time, you can charge slowly to minimize any possible heat damage to the battery, but if you're in a hurry you can throw the amps to it. My favorite feature is a selectable test that measures the amp-hour capacity of the individual batteries, so you can decide when it's time to throw the batteries away.
It does this by charging the battery, then fully discharging it while measureing the energy it produced, and then finally recharging it again. One bad NiMH can make a set run poorly. By reporting the exact milliamp-hour capacities, this charger lets you find which batteries are bad so you can get rid of them; this is a rare feature that I've not seen on any other NiMH charger in its class. !

Before reading a few of the highest ranking reviews for this product and the Maha Powerex MH-C9000 WizardOne Charger-Analyzer, I had no idea that I was reducing both the useful life and the storage capacity of my rechargeable batteries by using the 30 minute "quick" charger that was included with some Energizer rechargeable AA batteries I purchased a couple of years ago. Using this unit's test mode, I determined that some of my batteries' maximum capacity when fully charged had been reduced to 30% of the batteries stated capacity. Using this unit's refresh mode, I have been able to bring those 30% batteries up to about 85% of stated capacity. Other batteries that tested at about 80% capacity now are capable of about 95% of the stated capacity after being refreshed. Batteries that tested out in the mid 90% range only increased their capacity a few percentage points after being refreshed.
I chose this unit over the Maha Powerex MH-C9000 WizardOne Charger-Analyzer because some reviews state that the MH-C9000 emits a high pitched whine during operation and can require a ridiculous number of button presses to set the charge mode and voltage. The LaCrosse BC-900 is silent and the charge mode and voltage are easy to select using just a few button presses. I've used this unit to refresh 26 batteries and I am happy with the results. It works great for regular charging duties and I'm definitely going to use it exclusively to charge my new SANYO Eneloop 8 Pack AA NiMH Ready to Use Rechargeable Batteries batteries to make sure I get the best possible performance and longevity out of them. If you are thinking about switching from regular alkaline batteries to rechargeable's, I strongly recommend buying this unit and a supply of SANYO Eneloop 8 Pack AA NiMH Ready to Use Rechargeable Batteries or Rayovac Hybrid - Battery 4 x AA NiMH 2000 mAh rechargeable batteries. (As always, search the different Amazon.com listings to be sure you are getting the best offered total price.) It will be money well spent.
Beware the "Null"
Automatic Battery Charger Deal

This charger is a pleasure to use. I still marvel at its sophistication. I have encountered one small issue and thought it worth noting here along with a related solution in case anyone else runs into it. I was reconditioning/refreshing a set of batteries for my mother and one of them kept indicating "null" on the display screen. I finally figured it must have been a faulty or flat-out dead battery that could no longer hold a charge. So I took out that battery and placed in a bag for a school battery collection program. I went ahead and charged the others without a problem. A few weeks later, I was processing some more batteries and was checking them with a volt charger.
Just to double-check, I tested that "null" batery and saw that the battery still had an extremely weak charge on it, maybe .02 volts or so. It got me to thinking that maybe the charge was just too low for the BC-900 to even detect and thus it had simply read "null" and had not attempted to charge it. Assuming the battery was not faulty, but rather just too weak for the BC-900 to charge, I put it in a "dumb" charger over night. The next morning, I took it out of the "dumb" charger and put it back into the BC-900. PRESTO! The BC-900 recognized the battery and was able to recondition it. Lessons learned: when it comes to the BC-900, "null" doesn't mean unchargeable and there will still be an occasional need for a "dumb" charger.
