I have used it to charge different sizes and types of batteries at the same time. Using this charger, I am over 10 years on some of my rechargables, I can bring back batteries that have set for years in toys. If you put the battery in and the light doesn't blink, unplug the adapter from the charger and plug it back in. After one-four times of doing this, I can almost always bring a battery back. I have lost two out of almost 200 batteries in 10 years. I have two of these and leave them with batteries in them all the time.

This was the second NiMh battery charger I purchased via Amazon in the past 2 months, the first was the Ansmann Energy 8 Charger, and then the AccuPower. In both cases I was sent an either defective and/or used, but sold as NEW. I have good reason to believe that Sundance Solar sent me a "Display Model" of the AccuPower and/or returned one because the packaging was obviously "repackaged", finger prints, and the AC adapter was not the same shape as was pictured on every site I saw that carried the product. In both cases I returned the chargers and Amazon is the very best when it comes to returns, which is the primary reason I come back for more punishment...LOL

The problem with both chargers was the overheating of some batteries, which the "Smart Charging" technologies are suppose to prevent. When I charge batteries I always keep a small fan blowing on the charger at all times because I have found this keeps things "cool" and when one becomes "warm-to-hot", then you know for sure it is the charger.

Now I am ordering the C Crane QC2 Quick Charger-2, which is the exact same product as the Tenergy T9688, but under the Crane name it is a few dollars cheaper.

I do wish that Amazon would do a better job at the quality control end of their prime sellers to prevent these situations to begin with. By the way; if you do order this and get the one I returned; you will know it if you look through the manual as i used a tiny little piece of post-it in the middle to let the recipient know this was found defective and used. I put an obvious note inside the charger; knowing that Sundance Solar would quickly discover that and not look for the real note. May i recommend that everyone begin doing this so we can all be assured we are getting what we were promised. God bless all of you.

This is a great little battery charger. It charges AA, C, D and 9 volt batteries. I plug the lighter plug into a socket that is powered by my 12 volt solar panel on the roof of my house. It is used to charge all sorts of batteries for flash lights, remote thermometers and clocks, even the batteries for my Harris Dracon butt set, COIL tone generator, Progressive Tone Tracking Wand, and my cat 5 cable tester that I use at work.

Very easy to use, it will charge many different kinds of rechargeable batteries, and then will go into a maintain mode. Very "smart" unit; and supposedly one of the few that will charge batteries to their full capacity, a common complaint with cheap units. No problems so far, I leave it plugged in continuously to keep batteries at the ready. The only "con" in my opinion is the high price but after owning it and comparing it to a Radio Shack model I also own, it's worth the price.

I was looking for a charger that could handle 9V batteries and found that most are horrible in that they do not have automatic shut off so unless you pay close attention you can overcharge and damage the battery.

I came across this charger and saw that it not only handled 9V batteries better but that it can also charge most other standard size batteries. The status light for each slot lets you know what is going on and you can mix battery sizes.

This unit costs more but you get more. The quality of the charger is good too as it seems well made.

I bought two of the cheaper battery charging stations and both went bad in less than a year. Each one had a bad charging station within several months. This one is very well made and I wish I had paid the difference and got it first.

It will charge 9 V, c, d, aa, aaa with different batteries in each charging station.

Get this one, and you will be happy.

I was looking for a charger that I could use with either 120 volt AC current or from a 12 volt DC solar charged battery system. This one fits the bill, charges fast, and was reasonably priced.

I have owned several different rechargeable battery chargers and this is the first one that worked well. In fact, it works beyond 'well'. I can charge all different sizes of batteries (including 2 9-volt slots) up to D. I've even double stacked (company didn't recommend this) two AA batteries in each slot to make a total of eight. It still did the charging in no time flat. You can leave it plugged in with batteries inserted and it provides a trickle charge to keep batteries charged and ready to go.
What a great machine.

Bought this along with some new low discharge Tenergy AA batteries. First time I used it with no problems. Batteries charged, got quite a bit warm to the touch when I took them out, put the batteries in my son's remote controlled Battle Machine remote controlled car, and still going strong (the batteries) after 4 days. Second set of batteries I charged three of them appeared to charge (solid green light), but the fourth battery would not fully charge. Put them in my son's other Battle Machine and they worked less than a day. Recharged the exact same batteries and this time all of them appeared to have charged, but them back in the Battle Machine and it lasted all of 5 minutes. Also, when I charge the batteries they do not get warm at all, they stay completely cool. So now I am back using my old Rayovac chargers and at least with them the batteries take a good charge.

When trying to test the charger I have unplugged it to try to reset it and put the batteries in again - same thing. Unplug it and plug it back in with the batteries already installed - same thing. No matter what, I can't seem to get a good charge with this thing. Also according to the instructions when you first place the batteries in the charger the LEDs are supposed to stay lit solidly for three seconds while the charger "analyzes" the battery. Mine does not do this and goes straight to the charging mode - blinking LEDs

Looks like I will be returning this unit. Unsure if I want to exchange it for another one of the same. I paid $55 for mine which is a great price for this product (if it worked right) from Amazon through a 3rd party seller as I believe list price on this unit is $79.

For the money I thought this would be a good deal. After using this unit 20 times the unit won't charge any batteries. The only thing that happens now is all the lights just flash non stop like batteries are charging even when there are no batteries in it.
Just not reliable as far as I am concerned.
