TenergyTN438 16 Bay Battery Charger for AAA and AA Rechargeable Batteries, AA/AAA NiMH/NiCd Rechargeable Batteries Charger with AC Wall Adapter and Car Adapter

This charger works great and is very easy to use. It's almost foolproof if there's such a thing. We love that we don't have to buy new batteries all the time and throw old ones away. The convenience of it would be enough, but we're also saving money and trashing fewer batteries. We're happy.

I've been through some battery chargers; expensive ones, cheap ones. This is the best I've found.

As expected

good

worked as advertised

Love it, slow but works great and after a battery refresh it was able to fix some of my batteries which would not previously charge.

I've used this at Church for charging AA batteries. Works good. Cuts off after charging to avoid damaging your batteries.

Review of the 16 bay Tenergy charger. MY NEW FAVORITE HIGH VOLUME CHARGER. First of all I have probably bought nearly every decent charger over many years and this one is my new favorite. I also have the 12 bay version from years ago (still being sold) and that one was a little too finicky about being too sensitive to very low voltage / depleted batteries not being recognized (which required instilling a minimum charge using an old basic “non-smart” charger that doesn’t analyze minimum voltage) .NOT this one … it is pretty much near perfect compared to many others offering volume charging bays like this one.For example I had over 60 new AA & AAAs batteries still in their original package for several years I had forgotten about in some misplaced box that certainly were well depleted by now and decided I better open them and instill a charge using this new charger. Everyone battery except 1 was recognized and charged them all. NOTE this has “REFRESH” capability to discharge then recharge (optimize capacity & longevity), many high volume chargers do NOT have this feature. This charger is great if you have a lot of batteries and you need to simply keep them charged every few months just to keep them from getting too self-discharged, or if you have a smaller number of batteries where you can charge them all in one shot instead of swapping them out every several hours as with typical 4-bay chargers.I have many chargers from all sorts of manufacturers and many seem to stop charging too early, not fully topping them off or don’t have a discharge/recharge option. I also love the LaCrosse & PowerEx 4-bay chargers that offer a lot of charging control and are great for a small number of problem batteries that needs better attention to recovery. But with only 4 bays, it’s not practical if you have many that need charging. Those are best for intensive care purposes. But for volume charging - this one is the best I’ve come across. If you looking to a volume charger, don’t buy one without the Refresh or Discharge/Recharge option. This is the best in class for high volume chargers.
