The energy 16 is equipped with a user interface and battery loading technique. After inserting the NiCd/NiMH rechargeable battery, a diagnosis of the battery is executed and with damaged batteries a refreshing programm is invoked. Damaged cells are reactivated and the capacity of the battery is restored. Depending upon the condition of the inserted battery, the refreshing programm will pass through several cycles until the battery is regenerated.

User Reviews about Ansmann 5207123 Energy 16 Charger

I am new to rechargeable batteries, and this is my first charger. I bought it based on the positive reviews, thinking I was buying "the best" out there. I also bought some new sanyo eneloop AA batteries, which I fully charged with this unit, and then placed in my child's toy. When the toy stopped working, I removed the batteries and placed them back into the charger, only to get a "faulty cell" error message. I contacted www.Ansmann.us about the problem. They told me the sanyo cells were probably old and defective, and that I should return them to the manufacturer. I sent all 4 back to Sanyo. Sanyo returned them to me stating that the cells were simply depleted, and that they were able to fully charge them again with their own sanyo charger (approx. $10 retail value). I contacted www.Ansmann.us again, and they did not have an answer except for me to ship the unit across country for a servicing evaulation (I was never informed that the unit should indeed detect depleted cell. For all I know, the unit did exactly as programmed). I bought a sanyo charger as back up in case this happens again. I was very disappointed in this expensive charger and was frustrated that I spent so much time and effort. -- Did not recognize depleted cells.

I had a 3 in 1 battery charger from Rayoc before I bought the Ansmann. The features I like about the Ansmann is single cell charging, LED lights, 4 9volt charging, and fixing a bad battery. If you want to keep your batteries(investment) good then you can't go wrong with this charger. The price might be high but is worth it. -- Very good battery charger

This is a great battery charger. Worth every penny. Now I am in the process of converting all battery run appliances to NiMH Ansmann batteries. Go Green - Go Ansmann. -- Ansmann Rocks !!!

I searched for 2 weeks for the "best" charger to fit my needs, current and future. This is what I came up with. I was a little skeptical about the lack of reviews on this charger, but decided to get one anyway, especially with its 3 year warranty. I still have some older 600maH Nicads in my "fleet" that I felt would not be best to charge with Maha's MH-C808M, which charges at 1000ma minimum. I was also unimpressed with the so-called "LCD display" on the 808. The LEDs on the Ansmann are capable of displaying everything you need to know about the charging mode and battery condition, making an LCD display unnecessary. In my opinion, an LCD display would only be desirable if it displayed the actual maH accumulated charge of each cell. I very much wanted to have that feature, but sadly there are no chargers currently on the market that charge C and D size cells, and offer maH display. To that end, the LaCrosse BC-900 was considered, but I would've had to buy 3 of them to charge as many batteries as this model, and still could not charge Cs, Ds, or 9Vs, which I may add to my collection. So far, I have only charged "AA" size Nimh and Nicads with this charger, but I am happy to report that both the Nicads and Nimh peaked out nicely after the brief "Refresh cycle" this charger gives them. I sample tested some of the charged batteries by resting them 24 hrs, then discharging them with my Dymond (hobby) charger/analyzer (at 0.5C), which discharges to 0.8V per cell. Most of the batteries actually discharged more than their rated capacity after being charged with this charger, so I would have to say the -dV circuitry employed in this unit is very good at charging each cell to full capacity, and considering that some of my Nicads are over 15 yrs old, I would say the refresh feature has done its job to bring back some lost capacity in these cells. At $119, this is possibly the most expensive charger on the market, but I am happy with my choice due to its ease of use and sheer number (also sizes) of batteries it can charge. -- Almost everything you could want in a charger.

This charger has all the features I wanted! It can charge AAA, AA, D, C and 9V batteries in any combination. It acts as a battery level check when a battery is first inserted. The power cord is removeable for easier storage. The feature I like best is the ability to leave the batteries in the charger indefinitely, and not have to worry about overcharging them. It's not cheap, but worth every penny! -- This is the charger to buy
