Customer Reviews

Received the Tenergy T9688 charger in about a week. Unit was nice looking, with what looks like a better quality AC adapter. I put a battery in the charger my Duracell charger indicated was bad. I set it to discharge and then charge. After ten minutes it was still in the discharge phase, I canceled that mode and set it to charge. At no time did the charger indicate the battery was bad. When I removed the battery, my voltmeter indicated a 1.42 volt charge. I then charged 4 more AA batteries. These charged quickly,(30 minutes)and also were in the 1.42 volt range. The only negative I found was one of the slots has a weak spring to hold the prong against the negative end of the battery. The unit was quick, easy to use and batteries were warm not hot when finished. I also liked having the LCD with barsand words, indicating the status of the batteries, instead of lights that may not truly indicate the state of the batteries.

I was looking for a universal battery charger that recharges not only AA/AAA sizes but also the larger C and D sized batteries. I owned an Energizer Family Charger but became disatisfied because as it has a tendancy to not properly detect batteries. A review of that charger can be found here: Energizer Family Battery Charger
Now, about the Tenergy Universal LCD Battery Charger with USB Port...
After receiving my charger, I charged (didn't use the discharge feature) several AA sized batteries. Of the older batteries, some were detected as bad, but when I used a battery tester, there still was life in them. Out of a dozen relatively new batteries, one battery was detected as bad (when it really wasn't). I find that the bad battery detection process is sometimes inaccurate. It's probably best just to have a battery tester along side to test any "bad" batteries for verfication. For the one battery of the newer group that showed as "bad", I moved to another channel of the charger, then the battery charged up fine. I just hope this situation isn't recurring in which many batteries that still have life in them only get detected as "bad."
Each battery gets charged in it's own channel. That way charging in pairs is not necessary.
The USB port for charging/operating USB devices is a bonus. But I wish the USB port was located in the front or side instead of the back. That would be more convenient. Although I can't recharge batteries and charge via the USB port simultaneously, I still can leave my device (like a phone) plugged into the USB port while charging batteries. That way, when the batteries finish charging, the USB charging automatically kicks in. In otherwords, I can load the charger up with batteries, and plug in my phone to charge via USB and let them all charge overnight. When I wake up, the charger will have both the batteries and my phone all charged up.
What I like:
- charges sizes AAA up to D size
- LCD display shows individual battery charge status
- LCD display is bright and easy to read
- when batteries are charged, charger goes to trickle charge status
- USB charge port
What I dislike:
- USB port doesn't charge same time batteries are charging
- USB port located at back of charger, not in front
- the spring loading of batteries is a bit tight. Takes a little getting used to.
Conclusion. The chargers works fine as a universal charger (AAA through D sizes). The extra USB port is an added bonus. Though not perfect, the Tenergy charger gets the job done and is not as finicky as the Energizer Family Charger.
