Tednrhon: C & D batteries are very expensive. These recharge fast and work great. I did not have a problem with the batteries getting hot after charging. Not having to buy batteries is great. I would recommend these.

No Toro-caca: The only problem that I could find with my Tenergy Super Universal Battery Charger is that it is too small. It is so easy to use and does such a great job charging my Tenergy batteries that I wish I could run more batteries for recharge at a time. I like the "discharge" feature as it allows your batteries to go through a complete discharge cycle which means you will have a smaller charge memory thereby allowing to charge and use a greater % of the battery. Its a well thought of product that does what they say it does every time , quickly, safely and with the ability to monitor the charge status. I recommend this product for value, performance and ease of operation. The price of Lithium batteries in going through the roof so here is your solution.

Rusty: Reviewing Tenergy T9688 (4 slot D-C-AA-AAA and does AAAA as well)
Purchased 08 Feb 2023
All slots hold officially supported battery sizes tightly. (I have also used it for my tiny quad-A batteries and they work also.)
I probably should give it 5 stars but sometimes I think people tend not to believe a review if 5 stars are awarded by a user.
Charge time is moderate which is just what Tenergy advertises and it's just what I desire because the batteries last longer when gently charged. The discharge/recharge cycle works fine, too. I have no complaints. It's rock solid just like my other Tenergy charger.
I also have a Tenergy TN162 8-slot AA charger since Juy 2021. It works fine all this time. No problems.
The 4 slot T9688 has a 500 milliamp USB port. It's not worth much because practicalliy nothing functions on that little bit of power these days. The USB port only works when the charger is not charging batteries. I have a low draw USB lamp that uses 100 milliamperes. I plugged it into the USB port just for fun. The light plugged into the USB port comes on. If you then charge batteries, the light goes off...until the battery charging...
