Charger does what it's supposed to, keeps all my batteries charged independently, few things we have noticed using the charger is it does have a quirk where depending on which slots you put the batteries in some slots seem to be tied together lighting 2 slots rather then one independent slot as it's designed to not sure if this is my unit being defective or if it does this with all of them. Also if the rechargeable batteries are close to the end of service life the charger errors out or will give up trying to charge those specific batteries, however it's to be expected just throw the batteries out if they get to that point. In all , this charger is perfect and gets the job done. I would buy again and suggest it to anyone who needs a great multi slot charger.

This battery charger is the best one I've ever purchased. It came with the charger, an AC wall plug, and a DC car plug. I have only two issues with this charger, and both are not with the charger itself. PROS: - The charger ACCURATELY charges a very large variety of batteries (speaking strictly of mAhs) simultaneously. - The display is very easy to read. - As the specifications show, it does charge each battery independently. - The discharge functionality of this charger helps maintain battery life and provides a clean charge. CONS: - The charger itself has no real cons. - The manual provided, in short, sucks. Nothing in this product tells you how to switch from CHARGING to DISCHARGING, and visa versa. Nothing in this product or manual tells you how to turn on the LCD back-light. The words on the display of this charger which conveys the state of the charging process are truncated versions of the words, CHARGE, DISCHARGE, and ERROR. I know it sounds somewhat dumb, but there are a lot of people who will not understand what ERR means. In fact, the word ERROR in itself is ambiguous enough. - Before purchasing this product, I spent a few hours hunting down the same brand but with a 9V battery charging slot. While this brand did have a few, it was with the sacrifice of a large number of AA/AAA charging slots. Additionally searching outside of this brand was of a different make and model where the specifications of such did not clarify what I was looking for, or I needed to accept a substantial downsize with a substantial increase of cost. As great of a product as this is, I did not like having to settle for this product. Over all, I love this product. It works GREAT with Tenergy Premium & Energizer batteries. I would definitely recommend this product, or even a smaller version of it to friends and family.

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.
