desertcart.com: Tenergy TN438 16 Bay Battery Charger for AAA and AA Rechargeable Batteries, AA/AAA NiMH/NiCd Rechargeable Batteries Charger with AC Wall Adapter and Car Adapter : Electronics

Review: Tenergy 16 Bay Battery Charger is a Great Upgrade - I bought this charger for my Panasonic Eneloop AA batteries, and I’m really glad I did. At around $40, it’s a bit more than I originally wanted to spend—but after using it, I feel like it was worth it. The biggest upgrade is the 16 charging bays, which is a huge step up from the basic 4-bay charger that came with my batteries. Each slot has independent monitoring and auto shutoff, which I absolutely love. The display is bright and easy to read, making it simple to check charging status at a glance. It also comes with a car adapter, which is a nice bonus—even though I probably won’t use it much on the road. It supports both NiMH and NiCD batteries, as well as AA and AAA sizes, so it’s pretty versatile. With my old 4-slot charger, it could take days to cycle through all my batteries. With this one, I can get everything done way faster. It also has a “refresh” mode, which I assume helps condition or top off batteries, along with a discharge feature—both really nice extras. Overall, I’m very happy with this charger. It’s a big upgrade in convenience and efficiency.
Review: Ability to charge multiple AA & AAA batteries together at the same time. - Suitable for both AA & AAA rechargeable NiMH batteries, this was my second purchase after many years of use. Being a well built, I have not found a single issue. An excellent product a an excellent price.
