Tenergy TN480U 8-Bay LCD Display Fast Charger with 8 Pack AA Premium Pro Rechargeable Batteries

Throw away all your old chargers. Tenergy TN480U 8-slot beats them all. Small and compact, quality built, mix sizes (AA and AAA). fast, if you use "fast" wall charger. You can charge 1 battery alone if you wish.

This review is for the 8AA/charger bundle.I picked these up to use with some under-cabinet lights that were going through disposable batteries like a hot knife through butter. It's been nice to pop these out when they drain (they last far longer than the disposable batteries did), give them a charge, and pop them right back in.The charger is KISS genius—works on 2 battery sizes (AA/AAA), very intuitive, no struggling to get the batteries in or out, and tells me at a glance how the charge is progressing for each separate battery. Visibility of the charge meters is excellent. USB connection means you can plug it in anywhere (tho you'll have to supply your own AC wall wart or DC car adapter if you want to use those).There's a burr under my saddle, tho.If I had *nine* batteries, I could have 3 at the ready when I need them, then the 3 dead ones would be charged in time for the next replacement, lather rinse repeat. But no. Since it is only *eight*, I have to leave a light out of service while the batteries recharge—which is not particularly fast. (If slow charge means slow *dis*charge, I'm fine with that!) And I'm using the same 6 batteries over and over because I don't think about rotating them.The logical solution to that would be to buy more batteries. Except you can't buy the type of batteries that come with the charger. You can only buy 2 *other* kinds of batteries, with different power ratings. It's not clear to me whether it is safe to charge/use these incongruous batteries together, so I have not bought them. Not sure if the seller has discontinued these blue batteries and is just trying to offload them by bundling them with the charger, but not being able to buy more of the same has been annoying. I originally intended to give 4 stars because of this annoyance; but I'm so happy with the products overall that I didn't want to discourage anyone from buying this brand.My advice would be to buy the charger separately from whichever type of battery you prefer. Also consider buying multiple chargers based on the number of batteries you'll be using. (Yes I know they offer larger chargers, but they are AC/DC only, not USB.)

Arrived on time. Charges battery reasonably quickly. Less than 6 goes to charge all 8 batteries

This is an excellent charger especially because it has fully independent slots and does not require charging in pairs. NOTE: USB port or converter is required as it does NOT plug into AC. Even the base batteries work fine for my application: small battery-powered undercabinet lights.

This charger is great-- it can fit both AA & AAA rechargeable batteries and is way faster than the old Energizer Recharge station I originally got with the Energizer batteries. And you don't need to put them in 'in pairs'.It plugs into a USB charging port for power. And it will recharge several batteries in about 2 - 4 hours.It's has one quirk-- If you load ALL 8 slots with rechargeable Batteries and one or two of the batteries are more heavily discharged than the rest-- the device will stop charging and flash ERROR. It's like the unit cannot 'balance' the charging load if a couple of the batteries are more depleted than the others.You will need to recharge the heavily discharged batteries by themselves.Otherwise, This beats needing to have a pack of batteries for the remotes.

Got this to recharge our most common used household size batteries which are AA and AAA. We have a older charger that we never really liked. Hard to use and was a 50/50 that it was actually charging right. This one is simple and easy to use. Shows you it’s charging and shows when each battery is done. Between this and the rechargeable batteries we have saved a lot of money and are doing our part to help not fill up the landfill. We would buy this again.

This charger can charge 8 AA batteries at 500mA when you use a 5V 2A brick which almost everyone should have these days (one is not included per product page description). 500mA is an “ok” current for detecting the voltage drop at the end of charge when the battery is full. However, 700 or 1000mA would be even better for higher mAh batteries (like 2400+ mAh).I’ve ran about 60 batteries of various brands through here and the several I’ve tested with a multimeter have come out around 1.47-.1.49 volts. The batteries are warm at the end of charger but not hot which is another sign of a decent termination.Overall I’ve been impressed with Tenergy products. Their batteries average around the stated mAh that they advertise and aren’t inflated like EBL. I also have the their four slot combo charger (tn456) and like it as well. They are “good enough” products for a fair price. They don’t try to be too much and are very honest in their marketing.

I have an assortment of rechargeable batteries. The biggest selling point is that it can charge individual batteries. Other battery chargers require batteries to be charged in pairs. This doesn't work when certain devices use a set of 3 batteries. This charger can charge any combination of 1-8 of AA and AAA batteries. The display is also very useful to see if a battery is charging or full.The charger also keeps them topped up so just leave it plugged in for the next time I need batteries.Rechargeable batteries have also come a long way, in price, longevity, and performance. I use them anywhere I can as they last quite a while. Probably not as long as regular, non-rechargeable batteries, but long enough it's never been an issue.Buy this charger!
